Electronic Power Control, or more simply EPC, is electronic control of motor power. This system does not exist by itself; it works in conjunction with other systems. Together they optimize engine performance.
The advantage of cars with the EPC system:
- Fuel economy. Cars with the installed system have average fuel consumption.
- The system has an adjustment function. The car owner can independently adjust the sensitivity of the sensors to suit his requirements through a special program on his laptop.
- Compact and ergonomic. The system is quite compact and can be installed on any car.
Today, the EPC system is installed on Volkswagen, Skoda, Mercedes and Audi cars.
What is epc system in car
Unfortunately, or fortunately, not all automakers supply their cars with it.
The EPC system is installed on VAG and Mercedes cars. From the moment they began to be equipped with electronic throttle valves, the concept of Electronic Power Control appeared. This is an electronic control of engine power, which, in combination with other systems, helps optimize engine performance. If you don’t yet know what it is about Audi EPC, now is the right time to get to know it. If the EPC lamp comes on, check the brake pedal sensor - the “frog.” If we consider it from a purely physical point of view, then it does not exist as a system, because the warning lamp signals malfunctions that directly affect traction control. Often the warning light comes on due to a faulty brake pedal sensor.
Is it safe to drive with this indicator?
Considering that the warning light can come on even from a banal burnout of a light bulb or relay, then in some cases you can drive and not worry.
For example, a faulty rain sensor for many will not be a good reason to contact the service and pay 1000 rubles or more. for diagnostics. It’s another matter if the “Check Engine” light comes on along with the EPC and there is no “drive” of the engine. In this case, you cannot delay diagnostics. Otherwise, serious mechanical damage (piston replacement, timing belt, etc.) cannot be avoided in the next 100 km.
Why is the check engine light on? There are several reasons for this:
- Spark plug problems. For polo sedan, spark plugs are replaced every 60 thousand km.
- Refueling the car with low quality fuel. Fill up at trusted gas stations; using low-quality gasoline quickly clogs the fuel pump mesh and fuel filter. Additives used to dilute low-quality gasoline destroy the metal and lead to severe overheating of the engine.
- If the light comes on while driving, it means it's time to check the oil level. Change fuel oil for polo sedan according to the service book - every 15 thousand km.
- The engine compartment needs to be checked. The service will help you.
- Damage to the lambda probe. The lambda probe is a sensor of oxygen supplied to the engine. Most cars have 2-4 sensors. A car error scanner will help you find out which one is broken, if you have one.
- Catalyst failure. The exhaust system on polo sedan must be checked every 15 thousand km
- Need to clean injectors. To the service, check every 30 thousand km
- The need to check the fuel filter. Replacing the fuel filter on polo sedan every 60 thousand km.
- The need to replace the fuel pump. Replacement of the fuel pump on polo sedan - every 60 thousand km.

What do you mean by constantly - the EPC light comes on and stays on when the engine is restarted?

Yes, this applies to any critical errors. If something blinked at you, didn’t show up, or doesn’t appear again, don’t worry about it. An error has been recorded, the officials will most likely simply erase it and won’t even tell you about it. At the next maintenance, point this out, if it bothers you, ask.
You bought a good reliable car, enjoy it (one hundred thousand exactly
)

, You are meticulous. Your EPC blinked because a wheel rotation speed that was illogical to the nature of the movement was recorded, this is possible when the wheel goes around a large unevenness or rotates freely during a short-term separation from the road surface due to a jump or hanging out. It is likely that if you read the error right away it will be something like: failure of the rotation speed signal of one of the wheels. The control unit algorithm lights up the pictogram when an illogical speed signal is repeated within one driving cycle (until restart).

The same thing happened, after a restart it disappeared, for 20 thousand it did not happen again. The dealer threw up his hands

1.4 125hp Error EPC - Boost pressure regulator mechanical fault
Good afternoon Tiguan 1.4 125 hp Manual transmission. In 2 weeks the EPC error appeared 2 times. It was treated by restarting the engine. The car is new - the mileage is less than 2 thousand km. Diagnostics showed the following. errors (if necessary, I can post other parameters: Intake air temperature, Ambient air pressure, Terminal voltage, Boost pressure regulator, etc.)
What can you say - how critical?
3 Faults found: 18948 - Boost pressure control P0299 00 [096] - out of control range (less than lower limit)
Intermittent - Not confirmed - tested after deleting records Freeze frame: Status bits: 00000001 Priority: 2 Occurrence counter errors: 1 Mileage: 793 km Date: 2022.04.28 Time: 16:30:01 .
Volkswagen polo why the check engine light came on
The check light came on, what should I do? Firstly, this is always noted by experienced diagnosticians of the specialized car service "PIK", there is no need to panic. An indication of improper engine operation does not mean a major breakdown. And you shouldn’t prepare for expensive repairs. You need to contact a specialized service center.
The “check” lights up for various reasons. For example, misfires, it is possible that the matter will get by with a banal replacement of spark plugs. There are worse problems, for example, the valve timing is disrupted or the fuel injectors have died out. There's no point in guessing. A diagnostician from the specialized car service center “PIK” connects a scanner to a Volkswagen POLO.

EPC - what is it in a car?
One of the indisputable advantages of introducing the maximum number of electronic units into the design of a car is the ease of self-diagnosis - the car can inform the driver about most faults immediately at the moment they appear. But, of course, no one will turn the instrument panel into something like an airplane cockpit - and in some cases you have to regret this, trying to decipher on your own the meaning of the indicators that light up on the dashboard. Perhaps the most confusing thing for the driver is the EPC indicator, which is proven even by search engines: this abbreviation provides links to many forums dedicated to discussing the same question: “EPC - what is it in a car?” Well, let's try to figure it out.
Epc Volkswagen Polo sedan
Volkswagen POLO The check light is on. The owner of a Volkswagen POLO contacted the Pobeda specialized car service center. The “check” lights up for various reasons.
Is this made by VW or not? Replaced the valve and everything went away! Search titles only. Marelli, it’s a pity that they can’t be swapped, although it may be possible, but you need to know what signals from it go to the ECU, or if they exist at all, maybe it will be possible to swap another DZ with a CFNA motor. I look in the BZ, the throttle valve can’t come to an end -since there is nothing to break at all!
EPC on the Volkswagen dashboard
One of the main advantages of automotive electronics is the ability to self-diagnostics of the vehicle.
About Volkswagen: Buy Volkswagen Polo in Yekaterinburg
With the help of special systems and software, the car informs the driver about emerging malfunctions much earlier than a person could notice them. In this case, complete information is not displayed on the dashboard - usually only the indicators light up.
In order to find out exactly what problem caused the light to turn on, you need to carry out further diagnostics by connecting a laptop to the car.
What does the EPS financial indicator show - formula, calculation examples
Earnings per share are the most important factor determining the investment attractiveness of a company. One of the key indicators of net profit is earnings per share. In this article we will look at what the EPS indicator is and the features of its calculation.
What is EPS
EPS (from English “Earning per share”, translation - “Earning per share”) is a financial ratio that reflects the ratio of the company’s net profit to the number of shares.
EPS is quite popular when comparing the investment attractiveness of companies in the stock market. This is often the key foundation of investment strategies.
Additional information about the components of the formula:
- Net profit is equal to the measure of the same name in the report (Net profit). In some variations of EPS, such as weighted basis, preferred stock dividends are subtracted from earnings.
- When calculating the average number of ordinary shares, all changes that occurred during the specified period are taken into account.
Thus, EPS shows how much profit is generated per share, and the figure can be negative. In the latter case, it will no longer be a profit, but a loss per share.
In addition to the classic indicator, there are several modifications to the EPS calculation using additional data in the formula. Please note several variations of the coefficient:
- Basic (primary earnings per share) - When calculating the average number of shares, includes not only all shares outstanding during the calendar year, but also additional shares that were paid as dividends.
- Forward earnings per share: The calculation uses net earnings expected by financial analysts.
- Weighted - as already mentioned, implies the deduction of dividends on preferred shares from profits.
- Diluted (from the English “Diluted” - “reduced”) - takes into account the change in the number of shares due to the conversion of various securities. For example, bonds can be converted.
The total number of common shares may be considered either primary (primary earnings per share) or diluted (diluted earnings per share). The primary number includes those shares that have already been issued, are currently on the market and can be purchased or sold.
Diluted EPS: This is diluted earnings per share and is a more labor-intensive calculation that takes into account not only common stock but any other convertible security as well. Diluted EPS is one of the most accurate and conservative estimates available.
In this formula, the value of the denominator may also change periodically, but often the data presented in company reports is taken from Forms 10Q and 10K to facilitate calculations. Chief executive officers are required to report current data on both primary and diluted earnings.
Different types of EPS help you choose the most correct and accurate ratio for analyzing a specific situation.
EPS calculation example
For clarity, let's calculate Apple's earnings per share. Let us immediately note that for the American market you can get the EPS calculated on the Morningstar service in the Financials tab:
To calculate the metric manually, we need to look at Apple's annual report and find the earnings (net income) information. This figure is one line higher than EPS.
Common Mistakes
The codes and their interpretation will be the same for all Volkswagen cars, be it Polo or Sedan.
The most common mistakes:
| Climate control | |
| Errors 510, 511 | These are malfunctions of the temperature sensors in the central and, accordingly, in the foot compartment. |
| Errors 311,313 | problems with the temperature sensor in the panel or in the air supply duct. |
| Engine | |
| P0016 | says that the engine shafts are positioned incorrectly relative to each other. |
| The oil pressure sensor or its wiring is faulty. | |
| R2002 | indicates that the particulate filter has become unusable |
| Wiring | |
| U111300 | an error that occurs when there is a problem with the wiring. |
| Malfunction of contacts responsible for airbags. | |
| occurs when there is a simultaneous high electrical load, most often in traffic jams. What to do when it occurs? Restart the engine, reduce the load on the network. Then you should check the battery charge and all its wiring. If the error occurs systematically, the battery will most likely need to be replaced. |

About types of codes
The error designation indicates problems with airbags, particulate filter devices, camshaft or crankshaft meters, and rotary sensors. Coding of such a series confirms power system failures. There is no reason to worry when you see a light come on when you start the ignition. In this position, the electronic stabilization device is activated to indicate its operating status. Stable burning of the lamp - here you have to involuntarily think about “illnesses”. Periodic switching on/off indicates interruptions in contacts.
Special programs
Of all the existing programs for car diagnostics, the most common are:
- Vasya Diagnostic. This is a Russian-language program that is suitable for all operating systems. Works with all connectors and cords.
- VCDS is the original version of the Vasya Diagnostic program. Works only with a specialized cord.
- VAG EEPROM Programmer is a highly focused program with a small set of options.
- VAG K CAN is an improved version of the previous program.
- VDS-PRO is a program that works only with MS-DOS. Powered by a special cord.
This is a small list of common diagnostic programs. In addition to them, there are programs that diagnose a narrow area - electrical, transmission, etc. Such programs perform detailed analysis and are highly accurate.

Features of self-diagnosis of VW models
On the dashboard of Volkswagen cars, when problems occur, the EPC (Electronic Power Control) indicator lights up. Diagnostics allows you to obtain an error code, which should be compared with the table value, identifying the malfunction and making a decision on how to correct it. You can do this in a timely manner, restoring the car’s performance before the problem leads to more serious consequences, by contacting a car service center immediately after the light comes on.
If you have the appropriate software, you can try to decrypt it yourself. To do this you will need a laptop, a special adapter and a program. Typically the software comes with the kit itself.
