Smelly CQ

[John Cassidy]

Greetings!

Has anyone ever had suspicious smells in a Coupe Quattro?  Patient is a
late build with 140 kmi.  We've been trying to locate the cause for
months.  Smells like smoke, but not really like oil, not anitfreeze, and
not even exhaust smoke, to my old car nose anyway.  It's at its worst at
idle with the climate control on heat, A/C or defrost.  I cannot find
any noticable fluid leaks, and the exhaust appears tight.

My mechanic (really good guy) found an oil leak at the back of the valve
cover, so he steam cleaned it and repace the VC gasket, but to no avail?
It's going to the muffler shop tomorrow for an inspection.  In the mean
time, if anyone has a BTDT, I'm all ears!

Thanks in advance!
