Re: '91 200Q Problem - Wastegate Valve

["Mike Miller" <MikeMilr@email.msn.com>]

I believe the culprit could be the Turbo Bypass Valve - not the WGFV. First
thing I would check is the hose coming from the Intake Manifold (drivers
side) under the heat shield (passenger side) to the Turbo Bypass Valve. This
is famous for burning thru under the heat shield.

Subject: '91 200Q Problem - Wastegate Valve


My '91 200q will occasionally stall when decellerating or downshifting.  I
know that the turbo wastegate valve has on a number of different posts been
the culprit.  My question is was is the best way to articulate this to my
mechanic (independent Audi master tech) who wants to "check out everything."
I appreciate the fact that he would not want to replace a good part however
I don't want to pay him to troubleshoot a problem which has alluded many
mechanics (both Audi & independent) that he may not find.  Any "hard facts"
(TSB etc..) that anyone knows of would be greatly appreciated.  TIA
