Oil leak need help to locate source 2006 TT

Recommended Posts

The leak is leaving a smear of oil; on the top of the fresh air hose where it enters the box on the drivers side of the front valance and . Needless to say it is a pain in the butt to see anything up there without taking off either the front valance or the front drivers side wheel liner. I had the car on a lift and used a strong light but I cant see where it might be coming from. My suspects are a hose to the oil cooler or (heaven help me) a turbo. Not a serious leak but I would rather find it and fix before it becomes a problem. Any ideas ?

There is a TSB on an oil leak at the charge hose for the left turbo. It's very difficult to see in the area as you stated so maybe best to have the system smoke tested for leaks to help pinpoint the fault.

Perfect - the TSB shows exactly where I am seeing the problem and now I know I dont need to worry about it. When I get a chance I will check the Henn coupling as described. Many thanks!!
