When diagnosing an engine oil leak or a coolant leak on turbocharged V8 engines, it is necessary to use a borescope to identify if the source of the leak is from under the turbochargers.
Do not remove the transmission before performing this inspection.
Insert the borescope to the inside and outside of the induction pipes.
Incorrect readings can be avoided.
With the recent changing of seasons, it is possible to see a 20- to 30-degree temperature change from when the car is parked in the evening and driven again in the morning. Some customers may say they think the ambient temperature is not reading accurately. To achieve a "smoothing" effect of the displayed outside ambient temperature, the value shown does not instantaneously follow the temperature sensor measurement.
The system provides great ride & handling, but it can be complicated to service if you do not have the right training.
Technical Service Bulletins can be valuable in helping solve vehicle problems. But sometimes, it takes multiple TSBs to find a pattern failure or the “root cause” of a problem. In the case of the Audi/VW 2.0L Fuel Stratified Injection (FSI) engine introduced in 2006, three problems related to engine carbon and fuel issues are connected
Taking a guess can get very pricey if you can’t return the part.

This leads to perceived lower cooling power. The customer may also notice that external odors enter the vehicle. Related Articles –
