I've been trying for some time to clear a fault code that I've been told is an air leak.
On startup this morning I noticed a slight hissing, which on closer look was air passing through the joints on the secondary air pump (part 1 on this link https://www.realoem.com/bmw/enUS/showparts?id=CM12-EUR-04-2001-Z3-BMW-Z3_19&diagId=11_1659).
Firstly I assume that air through the joints is not normal - has anyone any experience on repairing one of these, or does not have to be a replacement?
Thanks, Paul
