Mercedes Benz 272 engine reported 0810 and 0814 failures

Mercedes-Benz 272 engine reported 0810 and 0814 faults You can use 2 Siyoupu cleaning agents, which are commonly used by PetroChina to clean oil storage tanks, and the refueling tank can directly clean the oil impurities, colloidal moisture, these. My colleague can use it, and his car is also continuously idling and shaking, and now it is very smooth.

The Mercedes-Benz 272 engine shows the fault code P0016, and the occurrence of such a seepage indicates that the mixture of the engine is too thick, because of the throttle of the engine.

sludge and carbon deposits inside.

Caused by excessive accumulation for a long time, clearing this fault code requires cleaning the throttle valve of the vehicle, which can not only clear the fault code after cleaning the throttle, but also reduce the fuel consumption of the vehicle for 100 kilometers.

The specific operation steps to increase the power of the engine and clean the throttle are as follows:

First, the air filter of the Mercedes-Benz 272 engine.

Tear it down. <>

Second, after the air filter of the Mercedes-Benz 272 engine is removed, the throttle door of the Mercedes-Benz 272 engine is exposed, and the throttle door is in a closed state at this time.

3. Put a wrench.

Insert the throttle door of the Ben Gaze Rent Void 272 engine and open the throttle door.

4. Spray throttle cleaner into the throttle valve of the Mercedes-Benz 272 engine, and brush it back and forth with a toothbrush at the same time.

5. After cleaning, use a paper towel to wipe the inside clean.

6. Install the air intake of the Mercedes-Benz 272 engine air filter back to its original position and the operation is completed.

Summary. Dear, glad to answer for you! Mercedes 272 Fault 2385 and 2389:

2389 represents the position of the intake camshaft (cylinder 2) that deviates from the specified value in the evening direction during cold starting, and 2385 represents the position of the intake camshaft (cylinder 1) that deviates from the specified value in the evening direction during cold starting. If there is no abnormal sound in the cold start, it is recommended to change the solenoid valves of the two intake camshaft adjusters to test the car first.

Dear, glad to answer for you! Mercedes-Benz 272 faults 2385 and 2389: 2389 represents the position of the intake camshaft (cylinder 2) deviating from the specified value in the evening direction during cold starting, and 2385 represents the position of the intake camshaft (cylinder 1) deviating from the specified value in the direction of the evening during cold starting.

If these two cold starts or disturbs the abnormal sound, it is recommended to change the solenoid valves of the two intake camshaft adjusters to test the car first. Shirt Shendan.

Mercedes-Benz is a world-renowned luxury car brand. Considered one of the world's most high-end car brands, it is praised for its flawless technical level, excellent quality standards, innovative ability to innovate and a series of classic coupe styles. Internationally, the brand is often abbreviated to Mercedes, while Chinese mainland calls it "Mercedes", Taiwan as "Mercedes", and Hong Kong as "Mercedes-Benz".

Resistant to purity. The solenoid valve and VVT wheel have been replaced.

Dear, if this situation needs to consider the engine computer.

As soon as the cold engine starts, the hot car is fine.

Dear, you should go to the repair shop to deal with this professional problem.

Yes.

0810 is the air flow rate of the secondary air system (cylinder group 1) is too small. 0814 is that the air flow rate of the secondary air system (cylinder group 2) is too small. Mercedes-Benz 0810 and 0814 troubleshooting methods are as follows:

1.When the engine has 0810 and 0814 faults, but there is no specific fault code, the engine may not be able to start, after verification, you can check the intake pipe and its hoses, starter, high-pressure spark, fuel supply system, fuel pump, spark plug, ignition timing and other starting system components of the working conditions, and then retry ignition according to the correct ignition situation.

2.If the engine speed is unstable after starting, high for a while and low for a while, you can check the working conditions of the ignition control system such as the air intake system, air filter, fuel injection system line, fuel pump pressure, and ignition timing.

3.If the idle performance is poor or the acceleration performance is poor, the high-pressure spark, oil supply pressure, and cylinder pressure can be detected.

The faults of the circuit are: fuse blowing, high-voltage coil breaking, low-voltage circuit breaking, center ignition wire falling off, splitter head leakage, and spark plug damage. Electronic failure mainly refers to the loss of function of the computer control board.

Oil circuit failure. Oil circuit failures may occur in the following areas: oil pump failure, oil circuit failure, oil filter blockage, carburetor failure, nozzle damage, etc.

Sometimes it happens that the fuel tank is empty and the owner doesn't know about it. Add a few liters of petrol and you'll be able to solve all the problems.

Summary. Hello, the result of your inquiry here is: the vehicle self-exclusion or self-confirmation of no damaged parts, including the timing chain, is the practice of it, the timing gear confirms the ** method, and the outside of the black solenoid valve should be replaced, the fault is still not solved, and it has been confirmed that there is no problem with these spare parts, but the vehicle is still normal, it is the relevant fault of the adjustment delay, then the maintenance suggestion is to decompose the engine and clean the oil channel of the engine, If the fault of the vehicle is still not solved after the final cleaning and decomposition, please consider the quality of the spare parts that you replaced, if you do not confirm it, please replace it again, if the vehicle can be accurately and effectively evaluated, then you can directly disassemble and clean the oil passage of the engine.

Mercedes 271 fault code P001477

Hello dear, I am inquiring for you, please wait a while, I will reply to you immediately Dear Hello The result of your inquiry here is: the vehicle self-exclusion or self-confirmation of no damaged parts, including the timing chain, is practice, the timing gear confirms the Mintan type ** method, and the outside of the black solenoid valve should be replaced, the fault has not been solved, Qiao Chaixin Hui and has confirmed that there is no problem with these spare parts, but the vehicle is still normal, it is the relevant fault of the adjustment delay, Then the maintenance suggestion is to disassemble the engine to clean the oil channel of the engine, if the vehicle is finally cleaned and decomposed, the fault is still not solved, please consider the quality of the spare parts to replace yourself, if not confirmed, please replace it again, if the vehicle can be accurately and effectively evaluated, then you can directly disassemble and clean the oil channel of the engine.

After replacing the chain sprocket, there is still a little abnormal noise.

Hello dear, it may not have been replaced.
