Hi my A4 b7 2008 2.0tdi is leaking oil from the exhaust what might be the problem. When it's running and riches 100k/h it starts smoking white smoke like a power station,then I stop and cool down the engine, after that when I try to start again its not starting I don't if it's the power from the battery or not

Could be worn internals or turbo.

 

[realslimshaver]

turbo oil return or supply line perhaps? also this is for "A4" or mkiv generation Volswagen jettas. that have the 1.9ALH or 1.9PD not audi A4s but your engine is simalar to the jetta mk5 mk6 mk7 2.0 tdi so you might have better luck posting there. or the vw passat tdi section

Bad turbo oil lines should not end up in exhaust. They can however trash the turbo internals which could pass oil to exhaust.
