That should be a relatively cheap test. They use a device that injects smoke
into one of the vacuum lines. When the see the smoke coming out somewhere they
have found the leak.

I had a 17544 code and a bad, fluctuating idle.
Mine was caused by a clogged "PCV" valve due to sludge. $17 part fixed it.
It was causing an internal leak (crankcase gasses into intake manifold).

http://members.***.net/ambox/audi_sl...inePeripherals
story here:
http://www.audifans.com/pipermail/a4...ry/001680.html

Probably not likely to be what's wrong with yours, but an easy way to test
for this would be to remove the hose (part #10 in that picture) from the
valve where it connects to the manifold and plug that manifold hole and see
if the idle improves.

Also to check for vacuum leaks I had read online that you can remove the big
hose that goes into the air cleaner housing and blow into it. I have no idea
whether that really works. When I blew into it, it took about 10 seconds for
the pressure equalize (hissing of escaping air to stop). (I didn't have an
external vacuum leak.)

well got the car back and yes there was a leak.
80.00 for the test
80.00 to replace the host and of course + taxes......

just wanted to say thank you everyone
