98 A6 quattro, leaks oil, the car's been in the shop 4 times for this issue(in 2 years time frame), the lower pan gasket has been replaced twice as well as the oil cap. Last time I had the Audi service check it out I have been told they need to take the whole engine apart= huge bill. I see I am not the only one having the "hard to fix" oil leak.
