VW Passat V6 – Engine Oil Sludge – Incorrect Oil Grade Used

Engine oil sludge does not just affect Saabs, take at look at the oil pan and lower engine on this VW Passat. That black gooey substance is not tar, but engine oil sludge. Unfortunately the car was switched over to a full synthetic engine oil too late in its life, for the first three years it was run on a conventional oil, you can see the results.

Audi A6 Quattro 2.8 V6 – Scheduled Timing Belt Service

Audi/VW timing belt replacement is a bit of a project as it requires the removal of the front nose of car. When replacing the timing belt it is critical to also replace the engine water pump and thermostat as they are located behind the timing belt, requiring belt removal to access. Not the most technician friendly design. It is also strongly recommended to replace the tensioner roller, serpentine belt and inspect the tensioner seals for oil leakage.
