Hello ,first Time Here , Trying To Learn The Ropes I Have A 1997 A4 1.8 Audi 69000 Miles . On The Morning When I Start The Car Its Smokes For A Minute Then Stops , A Local Mechanic Told Me I Must Be The Turbo Leaking Oil. Any Comment To Help Make A Dessicion Since The Turbo Is Very Expensive. Thank You In Advance. Joe Maxi
