Audi A6, turbocharged air diverter valve, mechanical failure. What to do.

1, too much carbon deposit in the intake system and intake valve roots, resulting in too lean mixture concentration during cold start. ?

Solution: Clean the air intake system.

2. The throttle is dirty and the air intake is insufficient. ?

Solution: clean the throttle. ?

3. The speed of the starter can't meet the requirements. ?

Solution: increase the speed of starter.

Turbocharging maintenance method

1, the oil and filter must be kept clean to prevent impurities from entering, because the fit clearance between the rotating shaft and the shaft sleeve of the turbocharger is very small. If the lubricating ability of the oil decreases, the turbocharger will be scrapped prematurely.

2. Clean the air filter on time to prevent impurities such as dust from entering the high-speed rotating compressor impeller, causing unstable speed or aggravating the wear of the shaft sleeve and seal.

3. Be sure to check whether the sealing ring of turbocharger is sealed. Because if the sealing ring is not sealed, the exhaust gas will enter the engine lubrication system through the sealing ring, making the oil dirty and the crankcase pressure rising rapidly.

In addition, when the engine runs at low speed, the engine oil will be discharged from the exhaust pipe through the sealing ring or enter the combustion chamber for combustion, thus causing excessive consumption of engine oil and "burning engine oil".
