01 a4 b5 sai failure?
Normally when I would turn my car on from a cold start it would make a loud vacuum noise coming directly from the secondary air pump. Recently I got a new battery so no codes are able to come up yet. But now when I start it from a cold start it goes straight too 800rpm and no loud noise. Does anyone think the pump has gone out? Thanks in advance
