The automobile steering wheel has come a long way through history. It all started with an ordinary cast iron handle. To turn left or right, you had to spin this slow, heavy thing around its axis. The work was not easy. Therefore, at the end of the 19th century, they developed a mechanism that became the ancestor of the very modern steering wheel that we are used to seeing in the car. It was much more convenient to use and, given the gradual increase in vehicle power, became a real technological breakthrough in the automotive industry.
The steering wheel is the part of the control system with which the driver interacts. Steering wheel movements affect other steering components.
On the Volkswagen Polo sedan, the list of system elements, in addition to the steering wheel itself, includes a steering column with electric power, a steering mechanism, a pair of rods with ends that are connected by hinges to the steering knuckles of the front suspension. In general, the scheme is quite standard for a modern car.
The steering wheel of the Polo sedan is equipped with an airbag and a horn switch. In addition, happy owners of expensive car trim levels can enjoy convenient control of the multimedia system using buttons on the left spoke of the steering wheel. There is also a button on the “steering wheel” that allows you to use your smartphone hands-free.
Installation of the Polo Sedan multifunction steering wheel (Polo Sedan)
Attention! This is an informational article, results are not guaranteed. The Site administration is not responsible for your actions.
In general, so that people have fewer questions, I decided to make a report on installing the multifunction steering wheel. I would like to immediately apologize for using photos of other forum participants and say thank you to them, it’s just that when I performed this operation myself I was guided by this material. I’ll get ahead of myself and say that for ease of operation and not to get confused in the connection, it is better to use wires of 2 colors (one is the Lin bus, the other is 12V power supply)
For installation we will need: - the multifunction steering wheel itself; — wire 000 979 009 E (2 pcs.), or the pins themselves N 907 647 01 (3 pcs.) (the pins will have to be crimped/soldered to the wire yourself, but it will be much cheaper) These wires/pins are used to connect the line bus to the block comfort and to the connector of the steering column switches; — wire 000 979 135 E (1 pc.), or pin N 907 326 03 (1 pc.). Fuse 3A. (this item is needed if you take power from the fuse block. I did exactly that.) - as well as the diagram.

1. Connecting wires to the connector of the steering column switches.
First you need to remove the terminal from the battery (it is enough to remove the negative one):
Next, turn the steering wheel 90°:
There are airbag mounting latches behind the steering wheel:
We insert a flat-head screwdriver (not very small so as not to break it) into the recess and, moving upward, unclip the pillow mount. If the pillow does not snap off on its own, you need to pull its edge while working with a screwdriver:
Then we turn the steering wheel 180° and do the same with the second airbag mount.
Next, remove the pillow and unfasten its connector (yellow) from the spiral cable:
Then unscrew the nut securing the steering wheel (for this you need to use a 12-sided star, size 12):
Having unscrewed the nut, we see that for the correct alignment of the steering wheel and steering shaft, there are special marks on them. We need to pay attention to this when we install the new steering wheel:
To prevent the spiral cable from spinning, you can secure it with electrical tape:
Further. Unfasten part of the steering column cover (under the dashboard) by pulling towards you:
Take a flathead screwdriver or something similar. From the end of the steering column casing we pry up its upper part and release 2 latches (on both sides of the rotating ring):
Lift this part up and remove:
Take a screwdriver (TORX T20) and unscrew 2 screws on both sides of the ring:
then remove the lower part of the casing.
For the convenience of further work, it is advisable to remove the “dragonfly”. To do this, loosen the screw securing the steering column switch (in the red oval) and pull it towards you from the steering column. Next, pull the connector lock up (in the direction of the green arrow), and unfasten the connector itself from the switch:
Now we need to remove the casing from the connector. To do this, you need to release 2 latches (green arrows) and tighten the casing (in the direction of the red arrow):
Having removed the casing, we see empty spaces 9 and 10 contacts in the connector. This is where you need to connect 2 wires with pins: No. 10 - Lin-bus (will go to the electronics unit) and No. 9 - 12V (power supply for the buttons):
It should look like this:
After connecting these 2 wires, we assemble everything in the reverse order. When installing a new steering wheel, do not forget to put it according to the marks:
Replacing a conventional steering wheel with a multi-function steering wheel
Since the cost of the Beats and Highline trim levels with a pre-installed multifunction steering wheel is significantly higher than the ComfortLine, owners install the navigation buttons themselves. Various colors of inserts for the multifunction steering wheel are available for sale. The cost varies depending on the place of purchase.
Preparatory stage: steering wheel of a new modification, electrical wire, Pins (Lin-bus), central 12V voltage supply cable, 3A fuse if the old one is no longer suitable for use.
- to avoid a short circuit, disconnect both battery terminals;
- turn the steering wheel 90°;
- On the rear side there are two latches for the standard airbag. Insert a flat-tip screwdriver and remove the cushion latches. Gently pull the edge of the plastic insert;
- We repeat a similar procedure by turning the steering wheel 180°;
- remove the pillow, disconnect the standard electrical power connector - the yellow cable;
- Using a “star” to “12”, unscrew the central nut that secures the steering wheel to the axle shaft. There is no need to mark the places of coincidences; the manufacturer took care of this in advance and applied the markings to the products. When assembling, it is enough to align the marks at the same level;
- To prevent the central power cable from twisting, it is fixed with tape or insulation;
- partially dismantle the casing of the lower casing of the steering column, slightly tilting it “towards you”;
- By analogy, we disconnect the upper part of the casing;
- Unscrew the screw securing the contact board. Among motorists it is called “dragonfly”;
- on the contact connector there is a free cell No. 9, 10. This is where we connect the ends of the electrical cable: one for 12V power, the other for the Lin bus;
- final stage: assembly and installation in reverse order.
- We follow the marks mentioned earlier.
But, even after successful installation and starting the engine, navigation on the steering wheel will not work properly, since it must be correctly connected to the central electronics unit. It is located on the driver's side, where the brake and accelerator pedals are.
To ensure maximum access to the unit, we remove the front driver's seat. There are two connectors inside the block: black and white, we need the latter. We find contact No. 17 (extreme position), insert our wire into it. Ready.
The final stage: connecting power to the buttons. We connect the second end of the wire of the steering column switch to contact No. 9. Now we enter data about the multifunction steering wheel into the electronic control unit of the Volkswagen Polo sedan. We enjoy the full operation of the multifunction steering wheel.
Connecting the wire to the central electronics unit
The block itself is located under the dashboard, on the driver's side, in the area of the clutch/brake pedal. A flashlight may be required for ease of use.
This work is carried out in a “not very comfortable body position.” It is necessary to position yourself so that your head lies on the floor near the pedals.
Personally, for the convenience of work, I removed the driver’s seat (the work took 10-15 minutes, but in the end, due to more convenient work, it took much less time) and lay down on the floor, with my head in the pedals.
So. We stick our head under the dashboard and see two large connectors, white and black (these are exactly the connectors of the electronics unit). We need white. Move the connector lock in the direction of the arrow:
and disconnect it from the block:
The tourniquet is very short and cannot be pulled out much. You will have to work in such conditions, wriggling like a snake
Now we need to remove the protective casing from it. To do this, release the latches (green arrow) and pull the casing off the connector (in the direction of the red arrow):
Next, we disconnect the connector into 2 halves and find contact No. 17 (it is the outermost, but all contacts are labeled, you can figure it out). We insert into it the second end of the wire with the pin (which was connected to pin 10 of the steering column switch). It should look like this:
That's it, when the wire is connected, we assemble everything in the reverse order.
Power connection for buttons (12V)
It remains to connect the second wire (the other end of the wire, which was connected to pin 9 of the steering column switch). We need to supply it with 12V. This can be done in different ways: take 12V from the radio power supply; take contact No. 15 from the light switch; as well as from the fuse block (unused socket). That's exactly what I did.
Let's consider this option.
I have comfort and fuses 49-52 (constant 12V) and 28-32 (appear during ignition) are not used, and if you look closely (circled in green), they have contacts:
I decided to use socket No. 49, but you can also use the top row of fuses (12V appears when ignition). Here you need to look at each specific case, because the circuit has changed and the location of the fuses has changed accordingly. Schemes can be found here
To connect, you need to remove the fuse box.
Remove the fuse cover (on the dashboard under the steering wheel), climb under the dashboard (with your head near the pedals). We unscrew one self-tapping screw of the air duct (everything is intuitive there) and remove the air duct itself. Next, unscrew the 2 screws (from the fuse side) securing the block and take it to the pedals. We move the protective cover to the side on the back side of the fuse box and we have access to the contacts:
12V is already connected to row B. In row A we find the contact socket that we will use and insert into it the second end of the wire that was connected to pin 9 of the steering column switch (you must first attach pin N 907 326 03 to it or connect it to wire 000 979 135 E). Next, insert a 3 A fuse and assemble everything in the reverse order.
All is ready. All that remains is to register the multifunction steering wheel in the electronics unit.
1. Before removing the negative terminal, it is advisable to turn on the ignition so that the airbag malfunction lamp does not light up. 2. There are already punched marks on the steering wheel and shaft, so you can safely sim and not worry about correct installation in the future. 3. When turning the steering wheel, it is advisable to leave the key in the ignition switch so as not to break the steering wheel lock (as written in the ElsaWin instructions) 4. After removing the steering wheel, if suddenly the return spring turns to an unknown number of revolutions, then before installing the steering wheel you need to make sure that it is in the middle position (the wheels are turned straight along the axis of movement), then we turn the return spring to the extreme position to the left until it stops, and then turn it to the right 2.5 turns. This will be its correct position. 5. Power to the Lin bus must be taken, as already mentioned, from any source, but it is desirable that power appears on that source only when the ignition is on, since this is exactly the case according to the scheme. Otherwise, a small current leak may occur while the machine is not in use. 6. On high-end vehicles without a premium package and without a multi-steering wheel, the Lin bus can be connected to the driver's door block (16 pins, purple-white wire), which is much more convenient and faster.
Some installation tips and tricks
- before resetting the battery terminals, turn on the ignition so that the system does not identify errors;
- when dismantling the steering wheel, leave the key in the keyhole;
- We align the steering wheel in the center if it was previously displaced during the repair process;
- It is advisable to supply 12V power so that it is supplied after the ignition is activated on the Volkswagen Polo;
- In case of difficulties with the cable connection, you can get power from the driver's door block.
Steering wheel
1. Open the hood, loosen the fastening nut...
... and disconnect the wire from the negative terminal of the battery.
2. We wait 15 minutes and, having unlocked the mechanism for adjusting the position of the steering column, ...
... we pull the steering column as far into the interior as possible and lower the steering wheel as low as possible. Then we block the steering column adjustment.
3. Turn the steering wheel to the left by 90° (the steering wheel spokes should be in a vertical position).
4. On the back of the steering wheel, use a flat screwdriver to unclip the airbag module fastening.
5. Turn the steering wheel to the right 180° and...
... unclip the second airbag mount on the opposite side. The airbag module should move away from the steering wheel.
6. Turn the steering wheel to the middle position (the wheels are straight). If this condition is not met, the airbag system may fail in the future!
Note
: Removal and installation of the steering wheel must be carried out in its middle position (the front wheels are in a position corresponding to straight-line movement).
7. Remove the driver's airbag module from the steering wheel.
Attention
: Before touching pyrotechnic components (for example, before disconnecting a connector), you must remove your “electrostatic charge”. To do this, you can briefly touch, for example, an unpainted metal part of the door lock.
8. Using a screwdriver, pry up the latch and disconnect the electrical connector of the airbag module. We finally remove the airbag module and place it to the side with the elastic padding facing up.
9. Take a key with a 12-sided star for 12...
... and loosen the steering wheel bolt (hold the steering wheel from turning with your second hand).
10. Check whether there is an installation mark on the steering column at the height of the marking. If it is not there, you need to mark on the steering column the position of the steering wheel relative to the column.
11. Using both hands, pull the steering wheel toward you to pull it out of its seat on the steering column.
12. After the steering wheel is pulled off, finally unscrew the fastening bolt and remove the steering wheel.
13. Installation is carried out in reverse order, and the following must be observed:
- Before installing the steering wheel, make sure that the front wheels of the vehicle are in a straight-ahead position.
- When installing a removed steering wheel: check that the marks on the steering column and steering wheel match.
- When installing a new steering wheel (without marks): the steering wheel should be put on in the middle position (the steering wheel spokes should be horizontal and the front wheels should be in a straight-ahead position).
- The airbag module electrical connector must be inserted all the way and click into place. Avoid pinching wires.
- Place the driver's airbag in the steering wheel and press it with both hands along the edges until it clicks into place.
- The battery must be connected with the ignition on. If pyrotechnic components (e.g. airbags, seat belt pretensioners) are not properly repaired after connecting the cable to the battery terminal, they may trigger spontaneously. Before connecting the battery, make sure that there are no people inside the vehicle.
- If, after installation, the airbag warning lamp indicates an error, you must interrogate the event recorder, reset it, and then interrogate it again.
14. After installing the steering wheel, take a test drive. If the steering wheel is not level, it must be removed again and rearranged on the splines of the steering shaft.
Volkswagen Polo sedan steering, features, faults
Volkswagen Polo sedan cars in all trim levels are equipped with electric power steering, a safety steering column, adjustable in height and reach, and a rack-and-pinion steering mechanism. The car's steering system consists of a steering wheel, a steering column on which an electric power amplifier is installed, a steering mechanism, two steering rods and their two ends, connected by ball joints to the steering knuckles of the front suspension. The control device in the electric power steering system is the electronic power steering control unit. Based on information received from torque sensors, vehicle speed and steering angle, the electric power steering control unit activates the gear motor to provide additional torque to the steering wheel.
Steering column Polo Sedan: 1 - lower universal joint of the intermediate shaft; 2 - intermediate shaft; 3 — upper cardan joint of the intermediate shaft; 4 — steering column mounting bracket; 5 — lever for adjusting the position of the steering column; b — ignition switch (lock); 7 — steering shaft; 8 — electronic control unit for the electric power steering system; 9 — electric power steering gearmotor
Steering Polo Sedan: 1 — left tie rod end; 2 — left tie rod; 3, b - protective covers; 4 — gear shaft; 5 — steering gear housing; 7 — right steering rod; 8 — right tie rod end
The electric power steering system, along with the electronic control unit, includes sensors, actuators, connectors and fuses.
The electronic control unit for the electric power steering system is connected by electrical wires to all sensors in the system. The electric power steering control unit determines the direction and value of the additional force depending on the vehicle speed and signals from the torque and steering angle sensors. As a result, the electric power steering ECU adjusts the steering force depending on the vehicle speed: the lower the vehicle speed, the less force; on the contrary, at high speeds the force on the steering wheel is maximum. This characteristic of the electric power steering provides ease of maneuvering when driving at low speeds and a feeling of feedback on the steering wheel when driving at relatively high speeds. The electronic power steering system control unit, mounted on the steering column, detects a malfunction in the system, identifies and stores its code. The control unit puts the system into emergency mode, turning off the electric amplifier, and at the same time, the warning lamp for a malfunction in the system lights up in the instrument cluster. The steering angle sensor is located in the electric power steering control unit. The torque sensor detects the angle of rotation of the steering shaft, converts it into an electrical signal sent to the electric power steering ECU, and enters the electric power steering control unit. The electronic engine control unit transmits engine speed and wheel speed data to the electric power steering ECU.
The electric power steering gear motor, mounted on the steering column, creates additional torque when voltage is applied to it according to signals from the electric power steering system control unit. The steering wheel is equipped with an airbag and a horn switch. Depending on the vehicle configuration, an audio system and telephone control unit may be installed in the left spoke of the steering wheel. The steering column is injury-proof, adjustable in tilt and reach, equipped with energy-absorbing elements that increase passive safety, and an anti-theft device that blocks the steering shaft 7. The intermediate steering shaft 2 is connected to the steering shaft 7 and the steering gear shaft by universal joints 1 and 3. The intermediate shaft consists of upper and lower parts connected to each other by pins. In the event of a frontal collision of a vehicle with any obstacle, the lower part of the intermediate shaft enters the upper part as a result of the pins being cut off. which makes it possible to reduce the length of the intermediate shaft and thereby cause less harm to the driver.
The steering mechanism is installed in the engine compartment. The steering gear housing is mounted on the front suspension cross member. Steering rods 2 and 7 are attached to the steering rack with ball joints. The tie rod ends 1 and 8 are connected to the steering knuckles of the front suspension using ball joints.
Checking the steering of Polo sedan
Check the condition of the steering regularly, as driving safety depends on it.
When inspecting the steering, pay special attention to the condition of the protective covers and threaded connections. Be sure to replace torn, cracked or lost elastic rubber covers, otherwise water, dust and dirt that get into the units will quickly damage them. Check the location of the steering wheel spokes, which, when the front wheels are in a straight position, should be located symmetrically relative to the vertical axis. Otherwise, determine the cause of the problem and correct it. Turning the steering wheel from lock to lock, check visually and aurally: — the reliability of the steering mechanism and steering wheel; — no play in the steering rod joints and ball joints of the steering rod ends; — no jamming or interference that prevents the steering wheel from turning. If you notice knocking or binding, disconnect the tie rods from the steering knuckles and recheck. If the knocking and jamming continues, remove the steering gear from the vehicle and have it repaired. 1. Check the condition of the protective covers of the tie rod ends. Replace covers that are torn, cracked, or have lost their elasticity. 2. Turn the steering wheel sharply in both directions (this should be done by an assistant), check visually and audibly for the fastening of the steering mechanism. Movement of the mechanism and knocking are not allowed. 3. Check for play in the ball joints of the tie rod ends. Replace the tips whose hinges have noticeable play. Also check the tightness of the tie rod end nuts. 4. Check the condition of the steering rod protective covers. Be sure to replace damaged covers.
CHECKING THE FREE MOVE (BACKPLAY) OF THE STEERING WHEEL With increased free movement of the steering wheel, it becomes difficult to control the car, since it reacts late to the driver’s actions. In addition, increased travel, which cannot be eliminated by adjusting the steering mechanism, indicates a steering malfunction (looseness of the steering mechanism, tie rods or wear of their parts). Check the steering wheel play with the vehicle parked on a level, non-slip surface. The play should not exceed 5°. You can also determine the play in linear units (mm) using the formula L = (5/360)пD, where L is the steering wheel play, mm; l = 3.14; D — outer diameter of the steering wheel, mm. For a steering wheel with an outer diameter of 370 mm, the play should not exceed 16 mm. You will need: a ruler, chalk (or tape) for marking.
1. Set the front wheels to a position that corresponds to the straight-line movement of the vehicle. 2. Install the ruler so that it is firmly fixed on the instrument panel, and the plane of the ruler touches the outer surface of the steering wheel rim. 3. Without changing the position of the ruler, turn the steering wheel to the right until the front wheels begin to turn. In this position, apply a mark to the steering wheel rim.
4. Without changing the position of the ruler, turn the steering wheel to the left until the front wheels begin to turn... 5. ...and in this position put a second mark on the steering wheel rim. 6. Measure the distance between the marks along the rim. It should not be greater than the calculated value. If the distance (steering wheel free play) is greater, the cause must be determined and eliminated.
How to remove the steering wheel of a Polo sedan
You will need: a 22mm socket, a screwdriver with a thin flat blade.
1. Disconnect the wire from the negative terminal of the battery. 2. Set the steering wheel to a position that corresponds to the straight-line movement of the vehicle. 3. Remove the driver's airbag module. 4. Loosen the bolt securing the steering wheel to the steering shaft, holding the steering wheel from turning. Do not unscrew the steering wheel fastening bolt completely, otherwise, when removing the steering wheel by hand, you may injure yourself if it suddenly detaches from the steering shaft. You can prevent the steering wheel from turning using the locking mechanism of the anti-theft device of the ignition switch. To do this, remove the key from the ignition switch and turn the steering wheel until the shaft is secured by the anti-theft device. After loosening the steering wheel bolt, disable the anti-theft device by inserting the key into the ignition switch and return the steering wheel to the straight-ahead position. 5. Use sharp blows to knock the steering wheel off the steering shaft splines. 6. Completely remove the steering wheel mounting bolt. 7. Remove the steering wheel. 8. Install the steering wheel in the reverse order of removal, aligning the mark on its hub with the mark on the end of the steering shaft. 9. Tighten the steering wheel mounting bolt to the required torque. 10. Install the airbag module in the reverse order of removal.

In addition, happy owners of expensive car trim levels can enjoy convenient control of the multimedia system using buttons on the left spoke of the steering wheel. There is also a button on the “steering wheel” that allows you to use your smartphone hands-free.
Checking the steering operation
The steering system on the Polo sedan, like on any other car, is subject to the influence of external factors. The steering mechanism, as well as the steering rods, tend to wear out. In the steering wheel itself, free play may gradually increase, which will negatively affect the operation of the entire system. Therefore, it is necessary to periodically check the condition of the steering.
Both knitting needles at the edges of the steering wheel should be positioned symmetrically. There should be no jamming when turning the steering wheel. The device must be held firmly on the axis.
If the car reacts late to the driver's actions when turning the steering wheel, then this is a clear sign of play. An increased stroke may be caused by loosening of the mechanism fastenings, rods, or wear of individual elements of the system.
The procedure for checking play on a Polo sedan is an important step that guarantees safe driving and increased service life of steering components. The test should be carried out on a flat, non-slip road. The maximum mark that the indicator should not exceed is 5 degrees.

During the installation of the alarm I encountered the need to remove the steering wheel.
And the dancing with tambourines began. Turn the steering wheel 90 degrees. There are latches on the back of the steering wheel that need to be pressed and the airbag should snap off. No matter how it is! After suffering for some time, I decided to ask the Drayvovites for help. I thank everyone who responded, shared advice and photos of the process.
Typical steering wheel problems and their solutions
- deformation, damage from an accident, traffic accident;
- short circuit of contacts, terminals, friction;
- malfunction of mechanical buttons due to wear or defect;
- Steering wheel jamming when turning from side to side.
To avoid many breakdowns and malfunctions, you need to systematically carry out a technical inspection of the Volkswagen Polo sedan, lubricate rubbing surfaces, and monitor the condition of the wiring insulation. If wear is detected, replace with new parts, contacts, and terminals.

Removing and installing the steering column trim. The device must be held firmly on the axis. If the car reacts late to the driver's actions when turning the steering wheel, then this is a clear sign of play. An increased stroke may be caused by loosening of the mechanism fastenings, rods, or wear of individual elements of the system.
The test should be carried out on a flat, non-slip road. The maximum mark that the indicator should not exceed is 5 degrees. The formula by which free play is calculated is as follows: A steering wheel with a diameter of mm can have a play of 16 mm, but no more. For the procedure, you will need a regular ruler and chalk to create marks: The ruler must be installed on the dashboard and placed so that it rests on the outer part of the rim.
We turn the steering wheel to the right and stop at the moment when the front wheels begin to move. Place a mark on the wheel rim. We measure the distance along the rim.
If it exceeds the figure obtained from the calculation using the above formula, then the backlash exceeds the permissible value. There may be several reasons for the malfunction: To fix problems, most often you just need to tighten the nuts.

However, if everything is much more serious, then in such cases the rod ends and other parts that have been worn out are replaced. One way or another, to get to the root of the problem, you have to disassemble the control system. And the first obstacle on the way is the steering wheel. Remove the negative terminal from the battery. If you do not turn off the power, the airbag may deploy. We wait 15 minutes until the capacitor that activates the airbag is discharged.
