secondary air pump has become very loud...
Is there something I can do to fix this, or do I have to keep driving my car sounding like a Hoover for the first two minutes of driving?
Its a 98 328i auto, and I've just noticed this to become much louder in the past month or so. Does this just need to be rebuilt?
