The Audi A6 has automatic rapid acceleration with the engine

It seems that this situation is quite common, recently I saw the same situation on the car quality network is not a few, and there are recent feedback from riders: "After the vehicle starts at low speed, it decelerates in advance when it encounters a red light, and the gearbox D2 gear automatically accelerates after releasing the accelerator, it is really strange to release the accelerator, how can it suddenly accelerate automatically without stepping on the brakes, this phenomenon has great potential safety hazards." I also pay attention to the fact that as long as the start of the 1st or 2nd gear automatically replenishes the fuel, it lasts for about a few seconds, and you need to brake in advance to control the speed of the car, "If you also have such a problem, you still try it in the car quality network feedback, only in this way can you hope to solve the problem."

Hello, rapid acceleration and shivering is not good for combustion, it is recommended to do oil circuit maintenance, check the spark plug, gasoline grid, clean the throttle, and clear the engine carbon deposit [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello. This should be an unstable idling. Clean the throttle. Check that the replacement spark plug will do. Thank you [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

What is the reason for the rapid acceleration and trembling of the Audi A6L You can use 2 Siyoupu cleaning agents, which are commonly used by PetroChina to clean the oil storage tank, and the fuel tank can be directly cleaned with impurities and gum moisture in the oil circuit. My colleague can use it, and his car is also continuously idling and shaking, and now it is very smooth.

Hello car owner, rapid acceleration trembling, may be the throttle valve is too dirty or the intake tract has carbon deposits, the spark plug gap is too large, it is recommended that you go to the repair shop to clean the throttle and intake tract carbon deposits, check the spark plug clearance, use the computer to read the fault code of the engine electronic control system, according to the fault code to specifically analyze the fault point, I hope to help you, I wish you a happy life!

The main reason for the Audi A6 idle jitter;

1. The most common cause of A6 jitter is that the throttle valve is too dirty or the fuel injector has too much carbon.

2. When the carbon deposition inside the engine is too much, the gasoline sprayed by the cold start fuel injector will be absorbed by a large amount of carbon deposition, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get started, 3. After the car is adsorbed, the gasoline adsorbed on the carbon deposition will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, resulting in idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Severe idle vibration is generally caused by engine cylinder failure, aging or loose foot rubber, carbon deposits, fuel system failure, etc.

Solution; The best way is to clean the oil circuit, clean it regularly, and use PNF fuel additives to solve the above problems caused by carbon deposits. 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 cause no good fuel to participate in combustion in the later stage, and the carbon deposition exceeds the standard, which is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

Regarding the problem of unstable idling, the main fault reason is the increase of carbon deposits in the combustion chamber, air intake, valve and other parts, which adsorbs some gasoline when the car is cool, and the mixture will be too thin when the engine is idling, resulting in unstable idle speed of the cool car. Therefore, you need to check whether there is too much carbon and dirt in the intake duct and intake valve, if it is too much, it will cause the cross-sectional area of the air passage to change, so that the control unit can not accurately control the idle air intake, resulting in the mixture is too thick or too thin, so that the combustion is abnormal or the engine shakes or even cannot start after starting. At the same time, it is also necessary to check the working status of the fuel injector and whether the pulse width of the fuel injection volume is up to standard.

It is also necessary to spark plugs, ignition coils and cylinder wires, whether there is a lack of cylinders. As a reminder, you should also pay attention to whether the canister is malfunctioning.

What is the reason for the normal speed of the Audi A6 engine shake throttle Engine fault diagnosis generally has several situations, the most common reason for the severe formation of car flutter in the engine carbon deposition is the engine internal department has a general cleaning agent, which can remove carbon deposition without disassembling the oil to clean the carbon sludge, which is very convenient to use, suspension differentiation does not clog together, and miscible with the oil will not lead to delamination, better and safer cleaning of your engine.

What is the reason for the normal speed and throttle of the Audi A6 engine high power is the large compression ratio, and the shake is obviously not the same thing, the fuel and the engine do not match, and it will naturally burn badly and shake. Especially in areas where ethanol fuel is used, ethanol fuel is not capable of targeting engines with large compression ratios. Especially after long-term high-speed operation.

The easiest way is to clean the oil circuit and return to the state of the new car, and the new car does not shake the handlebars, which is the reason. The Si Youpu refueling tank is normal to drive, and after a tank of oil, it will be cleaned, and it will be smooth. It really has nothing to do with the engine.

1.The solution to the weak acceleration of the Audi A6L is to clean the intake air and check the throttle, air intake, ** coil.

2.Test whether the vehicle can accelerate properly in manual mode. If it is normal, there is a high probability that there is a problem inside the gearbox, or the mixing ratio of combustible gases in the engine may be incorrect.

3.The Audi A6L2020 is based on the advanced MLBEVO platform, with a richer design space and a more advanced chassis structure.

4.The logo of the German luxury car brand Audi is four interlocking rings.

5.Today, it is a subsidiary of Volkswagen AG with its headquarters in Gstadt, Germany, and branches in China and other countries.

There are several reasons for engine shake:

1. The engine has serious carbon deposits, and the most common car with serious shake is that the fuel injector throttle valve is too dirty or too much carbon;

2. Ignition system problems, check the working conditions of spark plugs, high-voltage wires and ignition coils;

3. The oil pressure is unstable, if the first pressure of the pump is abnormal or the error and poor work of the inlet pressure sensor will cause the body to shake;

4. Aging of engine parts; Excessive chain carbon deposits in engine emissions absorb carbon from the gasoline of the cold-start injector, which results in a dilute cold-start mixture and difficulty starting.

Specific solutions to idle jitter:

1. The engine has serious carbon deposits. The most common cause of idle judder is excessive carbon buildup on the throttle or fuel 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. When the mixture is thin and sometimes thick, it will cause idle shaking after the cold starter. 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.

Solution; 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 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 factory 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 cause no good fuel to 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.

Analysis of the causes of car shake:

1. Suspension system problems.

Body shake is also related to the aging of the suspension system. It is mainly responsible for filtering out the shake of the engine when it is running, and if there is a problem with the suspension, these vibrations will be transmitted directly to the steering wheel and cab, affecting the driving. When the engine is idling, it is easy to cause shaking when the electrical system in the car is turned on.

The engine will increase the load when the electrical appliances are turned on, causing the idle speed to drop, and to compensate for the jitter caused by the idle slip, the engine will automatically increase the speed by partially. Therefore, when the electrical system is turned on, especially when the orange is rotten, the engine will often shake. This jitter is likely to be caused by the aging of the shock absorber and needs to be replaced in time.

2. Tire problems.

For tires, the tire must be balanced once when the car is replaced with new tires and new steel rims, otherwise the steering wheel will be prone to shake when the counterweight is uneven. If you find that the tire weight is not equal, you need to add lead to the inside of the rim to average the weight of the tires on both sides. Whether it is a general steel ring or a lightweight aluminum ring, it may deform or crack when subjected to a certain external force.

Deformation of the rim can cause shaking when driving, uneven weight of the rim can also cause shaking when driving, and incorrect angle of the rim can also cause shaking when driving.

3. Throttle problems.

The most common cause of car shake may be a dirty throttle valve and excessive carbon build-up in the fuel injector. After the car travels for a period of kilometers, the throttle valve will be too dirty and the throttle will not close tightly or the idle motor will be stuck, resulting in the engine idle speed is too high, and the carbon deposits generated by the engine in the process will also cause the vehicle to shake, especially when starting the car, the engine will shake more than normal, and even sometimes there will be a phenomenon that can not be started at one time. Therefore, when the body shakes, the first thing to do is to check the throttle and fuel injectors.

If you find that the throttle valve is too dirty or the fuel injector has too much carbon deposit, you should clean it with fuel injector cleaner or Yuanwei throttle cleaner in time.

4. The oil pressure is unstable.

If you still find that the body shakes after these are finished, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is not normal, the intake pressure sensor is wrong and improper work will cause the body to shake.

Look at the fuel injectors and spark plugs. Hope, thank you!

The common problem of the 10 Audi engines is still in the chain.

The reasons why the car cannot accelerate are carbon deposits, fuel system, air intake system, engine overheating, etc.

1.Carbon deposition.

The carbon deposits here include cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, intake carbon deposits, etc. These good or positions happen to be closely related to the power output of the engine. When the engine deposits too much carbon, the ignition energy of the car will be reduced, and the air intake efficiency will also be reduced, which will eventually lead to a decrease in engine power, resulting in weak acceleration and muffled sound.

2.Fuel system.

Adding an inappropriate fuel label (such as 90 plus 93) leads to a decrease in the output and power of the car; Or because the breather hole of the fuel tank cover is blocked, resulting in the fuel tank switch, fuel filter and the oil pipe bridge sock between the fuel tank and the carburetor partially blocked, which can not meet the required oil supply, resulting in the mixture being too thin and the engine acceleration is weak.

3.Air intake system.

Empty gas is one of the engine's powers**. If the air filter is not cleaned in time for a long time, it will lead to blockage, insufficient air volume, and the combustible mixture will be too thick, which will reduce the engine power. If it is a vehicle with a turbocharger, once the supercharger fails, even if the throttle is given, the engine will still be sluggish and will not **.

4.The engine is overheating.

Insufficient oil, insufficient engine coolant, faulty engine radiator, etc. It will increase the load on the engine, resulting in poor engine heat dissipation. Overheating of the engine can lead to poor lubrication, increase mechanical wear, reduce engine power, and cause the engine to accelerate weakly.

The throttle is too dirty, and there is too much carbon in the fuel injector and air intake. The user can simply clean the throttle.

In the case of a cold car, carbon deposits will absorb a part of the fuel, and if the fuel does not completely enter the cylinder for combustion, it will produce unstable idle speed and difficult starting.

The other condition is more serious, which may be caused by the deformation of the steel rim, which requires the owner to go to a professional repair shop for inspection, which generally occurs in vehicles with a long service life. Generally, when the car is replaced with new tires and new steel rims, it is necessary to do a tire balance, otherwise the steering wheel will be prone to shake when the counterweight is uneven. Body shake will have an impact on driving comfort and handling judgment.
