'99 A4 2.8 Sounds like plane when started (air pump?)
Please help! I have a 99 Audi A4 2.8L, tiptronic that almost every time I start it sounds like a jet engine taking off. I was told by a mechanic that it is my air pump that kicks on to help warm up my engine but it is unbelievably noisy. Sometimes this pump comes on when I am driving as well (although not often). It will stay on initially for about a minute then shut off. I also have an ABS light that is flashing with the parking light. Could this be an abs pump or is it the air pump? I know others that have audis and this isn't normal. Please help as this has been going on for a long while.

Pretty common problems - the secondary air injection pump (SAI) is plastic and splits open as the plastic becomes brittle. Replacement is pretty quick. For the ABS check the obvious stuff like brake fluid level/pads/ABS wheel sensors first, otherwise you likely need the ABS module repaired. Getting codes via VCDS will help identify problems in that area.
Search for ABS Module Repair Toronto - there is some someone their who repairs those things. I've also seen a company named Modulemaster pop up in various threads on other forums.

if you have the lights on, then look and see if its a B5.
you're a 99, yep, its the ABS Module.
fairly easy to replace, its just finding one or getting yours sent out.
I just had this, and I found one in a Parts 2001 A6 with the 2.8 (same ABS module as ours) for $200 and just swapped em.
For the Secondary pump just bite the bullet and see what the stealership has.

Do you know where I can get instructions on how to remove the air pump myself?
