2002 Audi A4 1.8L Exhaust Type Noise
Posted to European Driveability on 11/5/2012 14 Replies

I have an exhaust type noise coming from the air filter housing after starting the [...] lasts for about 15 seconds. It's coming from the secondary air pump,noise goes away when pump shuts off, has no codes present. Is this noise normal?
