Most VW/Audi engines from 94 and on utilize an electric operated air pump. On a 1.8t its usually mounted under the intake manifold. You should see a corrugated plastic hose running from the pump to the air cleaner housing. All 1.8t engines are prone to torn vac and intercooler hoses. I worked on a new VW Jetta the other day and at a cold start, you would hear the air pump activate for about 10 seconds. I swear that pump was so loud and high pitched, it literally sounded like a twin screw supercharger at full bore but without the engine noise to match! Raj In a message dated 7/30/2008 5:26:56 P.M.

He mentioned it was no were near the timing belt and on the back of the engine so I'm wondering what it really was.

SOLVED I don't know why, but the Germans do like to put vac pumps on to boost the signal to the brake booster. They failed back when I still worked on Audis, guess nothing has changed. Back then we would just bypass them and the cars stopped just fine on the engine vacuum.

SOLVED I'd like to see the pump and be told why it has a vacuum pump on a non-diesel. Now if it was an air pump for emissions control purposes that's different.

I have no idea why it has vacuum pumps except to make general comments about the design of German cars. :) --Ian _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower **************Get fantasy football with free live scoring.
