Hi all,
I've got a problem with my 2000 A4 1.8t ATW. With in the last couple of days the secondary air injection pump will start running for a minute or so then stop for 5-10 minutes then start running again. The happens for several hours even when the engine isn't running.
I used my VAG-COM to check for codes and readiness tests. There were no codes for any system and all readiness tests passed including all emissions tests.
Any ideas as to what is happening and what next to check to solve this problem?
Thanks
BTW: I also posted this in the VAG forum at AudiWorld.
