The car shook while Magotan was moving, and the EPC light was on

1. The EPC lamp is mainly caused by the dirty throttle body, which can be solved by cleaning and re-matching the throttle;

2. There is a leak in the air intake system, which causes the engine control unit to light up the EPC warning light after detecting the problem; At this time, it is necessary to check the air intake system of the vehicle to solve the leakage problem;

3. The failure of the brake light switch will also lead to this phenomenon; At this time, it is necessary to check the fault of the brake light switch and repair or replace it in time;

4. Leakage in the crankcase ventilation system can also lead to this failure; At this time, it is necessary to check the fault point of the crankcase ventilation system of the car and solve the leakage problem.

The car shook while Magotan was driving, and the EPC light was on The engine is very good, but the oil circuit is expensive and needs to be cleaned regularly, and the oil tank of the gas station needs to be cleaned once every 2 months, not to mention that the fuel tank of the family car is not sealed. Add a company with fuel additives in the fuel tank to complete the cleaning.

Hello, the EPC light is on the electronic throttle failure, it is recommended that you go to the repair shop to use the decoder to read the fault code and then repair it specifically, in addition, the Volkswagen car will turn on the EPC light and the brake light will also light this light. Hope mine can help you. [If you have a problem with the car, ask the car master.]

It's mine. This is also the case, tossing for half a year, anyway, the speed of more than 90km h is easy to alarm and dare not open, the low speed is normal, that is, the engine is not so stable! It lasted for more than half a year, the high speed did not dare to go up, more than 100 to keep for a while, the engine and EPC alarm, the vehicle acceleration was weak, the head of the oil car jumped violently, only to stop the engine and restart and return to normal, continue to drive for a while!!

Now I went to the repair shop to check and found that the exhaust pipe followed up the trachea with a large amount of oil accumulation, and the repair shop decisively replaced the exhaust pipe and cleaned all the intake and valves, and the problem was solved! Spent more than 1,000! Happy!

Hello car owner, there are many reasons for this fault light to be lit, the throttle is too dirty, the cylinder burns too thickly, and the brake bulb is damaged. 4S shop professional technician, 10 minutes to solve. 】

When the Magotan car shakes while driving, what is the matter with the EPC light on, and the fault light is on, it means that there may be a fault in the electronic throttle system, and the fault may affect the normal use of the vehicle. The electronic adjustment of engine power (electronic throttle), usually the leakage or blockage of the intake system, excessive carbon deposition on the throttle, substandard fuel selection, and valve jamming will cause the fault light to light up. After running the two divisions of the general fuel tank, the idle shake will disappear when the idle shake is turned off.

Hello, follow your description, this should be the phenomenon of your vehicle having a missing cylinder [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The reasons for the severe shaking of the car are as follows:

1. Excessive carbon deposition in the throttle, fuel injector, and intake duct may lead to serious start-up shaking of the car.

2. There is too much carbon deposition inside the engine, and the gasoline sprayed by the starting fuel injection head will be absorbed by a large amount of carbon deposition, resulting in too thin the starting mixture, which makes the starting shake greatly.

3. Mechanical failures such as ignition coils, spark plugs, fuel injectors, etc., resulting in lack of cylinders; The oil pressure or cylinder pressure is low, resulting in insufficient power, etc., which causes the car to shake greatly when starting.

4. The oxidation or grade of the engine oil is low, mainly due to poor low-temperature fluidity, and the cold start protection of the engine is not in place, which makes the car shake badly when starting.

Specific solutions to idle jitter:

1. The engine has serious carbon deposits. The most common cause of idle judder is excessive carbon build-up on the throttle or injector. When there is too much carbon deposit inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by the carbon deposit, resulting in a mixture that is too thin and making it difficult to start.

After landing, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the engine and burned, which will thicken the mixture. The mixture is sometimes dilute and sometimes thick, which will cause idle jitter after cold start. The lower the temperature, the greater the amount of oil required for cold starts, and the more the presence of carbon deposits affects cold starts.

The solution is to clean the carbon deposits at the throttle and injector.

2. Poor ignition system and poor ignition of spark plugs will also lead to engine idling and shaking. If there is a problem, check if the ignition system is faulty and if there is too much carbon deposited in the spark plug.

3. The oil pressure is unstable. If you have cleaned the engine carbon deposits, cleaned the throttle valve or replaced the spark plug, and there is still the problem of body shaking when idling, it is recommended to go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal. If the oil pump supply pressure is not normal or the intake pressure sensor is incorrect, it can also cause the body to shake when idling.

4. The best way is to clean the oil circuit, clean it regularly, there is no specific experience in the research and development parameters of the clean engine from the beginning of the new car, coupled with the continuous improvement of emission standards, can not adapt to the change of fuel, all manufacturers of the engine are unable to solve this jitter problem in the short term, plus the fuel quality is not very good or the initial fuel of the new car is stored for too long, resulting in a rapid increase in the colloidal composition of the oil circuit, which will continue to pollute the fresh fuel and lead to no good fuel can participate in combustion in the later stage. The occurrence of excessive carbon deposits is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits. The use of PNF dope fuel additives can solve the problems caused by carbon deposition.

Hello, the Magotan EPC light is on because the intake and exhaust system is faulty, which may be caused by carbon deposits and other reasons, it is recommended to check.

In this case, it is recommended to go to the repair shop in time to check and find the faulty ** for maintenance, so as not to affect the overall safety performance of the vehicle.

Hello, it is recommended to go to the local 4S store computer to detect the specific fault, and then deal with it according to the fault

VolkswagenThe faults that occur when the EPC light is on are as follows:

1. If the battery is low, the EPC fault light will be on.

2. The brake light is not on, and the brake switch and circuit need to be checked.

3. It is a throttle.

If it is dirty, it should be cleaned.

4. If there is a problem with oil, the EPC fault lamp will also be lit.

What does it mean for Volkswagen EPC lights to be on

Volkswagen's EPC light is an electronic power control fault light, which indicates that the engine and electronic systems are malfunctioning, usually due to spark plugs.

If carbon deposition is caused, it is necessary to check whether the spark plug is seriously carbon deposition, and then clean the throttle valve. The throttle valve is a controllable valve that controls the entry of air into the engine, and the gas enters the intake pipe and mixes with gasoline to form a combustible mixture, thus combustion. EPC stands for Engine Electronic Power Control System, and many people call it Electronic Throttle.

The EPC indicator is more common in Volkswagen cars, and the indicator light is on to indicate that the vehicle is malfunctioning.

EPC indicators are more common in Volkswagen cars. When the key door is opened, the vehicle starts self-checking, and the EPC indicator lights up for a few seconds before turning off. If the vehicle does not turn off after starting, it means that the vehicle's mechanical and electronic systems are malfunctioning.

Generally speaking, there are two possibilities for the EPC light to be on. First, the throttle is dirty and should be cleaned. Another situation is that the brake light is not on, and you need to check the brake switch as well as the wiring.

Also, due to oil problems, the EPC faulty lamp will also be lit.

There are the following reasons:

1. Failure of the air intake system, such as leakage or poor blockage;

2. The throttle body is dirty and has too much carbon;

3. The selection of fuel is not up to standard;

4. Abnormal cylinder pressure and poor working conditions;

5. Valve failure, stuck or carbon deposit, etc.;

6. ECU failure;

7. Occasional failures and false alarms.

Solution: 1. Troubleshoot the intake system, select the fuel up to standard, and clean the throttle body;

2. Remove carbon deposits from relevant parts;

3. Re-flash ECU-related data.

When the EPC indicator light is on, the owner can first try to turn off the engine and restart to see if the EPC light is still on, if it is not on, it means that there is no problem, but the EPC light is affected and false alarm; If the EPC light is still on, or it is frequently lit, then the owner will have to take the previous solution.

Hello, this suggestion to check whether the throttle is too dirty, EPC is the engine throttle fault light, I hope my answer can help you, if you don't understand something, you can continue to ask me! Have a great day! [If you have a problem with the car, ask the car master.]

The battery light on the car meter is on the battery problem:

1. The motor power generation voltage is lower than the battery voltage, the generator does not work or the power supply line is faulty, and the vehicle is powered by the battery, so the generator and charging line should be repaired in the repair shop.

2. The battery light on the dashboard is a warning light that the generator does not generate electricity, and the light should be lit when the ignition switch is turned on to the ON gear normally, and it will be extinguished after starting the engine, and the light is still on after the car indicates that the generator may not generate electricity, or there may be a problem with the line, and it is necessary to check the maintenance station immediately.

3. The car can still operate normally when the battery indicator light is on, because the car can continue to use the electric energy stored in the battery until the electricity in the battery is used up. Once used, no part of the car will work. When the battery indicator light is on, the car can still be driven to the garage without damaging any parts.

However, you must rush to the garage before the battery runs out and the car turns off.

The car instrument keeps flashing:

1. Generator failure, line failure, charging regulator failure, loose components, etc. It is recommended to use a testing instrument to check the charging capacity of the generator (turn on all electrical settings). Minimum above.

Check the relevant circuits of generators and electrical equipment, and if the above inspection is normal, it is recommended to replace the generator assembly.

2. There is a problem with the wiring on the back of the instrument. It is recommended to go to the repair shop, remove the instrument to check whether the instrument circuit is loose, and whether there is poor contact on one side of the circuit board.
