I just had the oil changed for my 2001 Audi A6 Quattro. They stated that I had a major engine oil leak, major trans pan leak and rear differential leak. There is also a strong burning smell when the car is idling. For example when I am stopped at a light or when I am heating up my car in the mornings. What exactly is the problem and how much will it cost to fix all of this?

 

These engines leak from everywhere.

Go see a qualified European auto mechanic. Have him check it out. The trany needs to be serviced ASAP or you can just throw the car away!!!

The trans will take a service-Filter, Pan gasket, and fluid
The rear diff is one of the seals.
The other leaks need to be looked into. Oil can be running down from the valve cover gaskets and rear seals, cam adjusters etc. or it could be the oil pan as well or all of the above unfortunately
