RE: 200Q Exhaust Leak
I had a shop tell me that the barely audible noise I was hearing on start
up was an exhaust leak and that I might want to "check it out". When I
attempted to tighten the nut on #1 cylinder the stud snapped immediately.
That led me down the slippery slope to manifold removal - cracked in
several places, 5 broken studs, and R&R of the head for repair (but I did
it myself). Others on the list have noted that Audi considers the manifold
an expendable component, and based on my experiences I would have to agree
completely. On a positive note, replacement of the one piece swiss cheese
manifold with a gas tight two piece has led to noticeable improvements in
driveability. While only subjective, the car just works better and the
engine pulls strongly through the RPM range with no hint of hesitation.
Btw, the exhaust gaskets were toast, but that wasn't the real problem.
