Question about 1998 Audi A4
1998 audi a4 1.8t has lost take off acceleration,also does not seem to accelerate like it should at highway speeds. no warning lights, idles smooth. could this turbo problem?
It's possible that the diverter valve (DV) has failed. The OEM valve has a plastic diaphragm inside and it can crack. If this happens, the car will leak boost air and will lose power as a result. Go to www.audiworld.com, click on Resources, then Tech, and then go to the engine article about replacing/upgrading the diverter valve - it'll show you where it is and how to do it.
