Re: Exhaust Resonance
i sopke to a guy at audi about his TT, he had a boost leak and it made his exhaust sound different.....he was getting more fuel less air......is was the diverter valve sticking open....guess that would be venting to much boost?
also i think i might have a boost leak it comes and go's they cant find it?? on the scan/log its shows its 8lbs-17lbs also the engine light come on/off....but the exhaust sound is still the same?

Re: Exhaust Resonance
Thanks guys:
The exhaust system is stock which for 225 has dual rear outlets, and the performance is fine. I just bought the TT and am not too familiar with it. The resonance is only present at 3200 RPM doesn't matter if I'm shifting up the gears or down. What other symptoms would appear with sticky diverter valve? How can I tell if that is it?

Re: Exhaust Resonance
I get the exact same problem in my 2001 225 TT, 140000km. It is only at 3200 rpm. It has been present for over a year. I had Mechanic trouble shoot it. They looked under the car and seem to think the vibration from heat shroud/shield up near the front of the exhaust system. They said there might be a small crack in it. It doesn't affect engine performance and they think it is not worth spending money on it. I am in Vancouver.

Re: Exhaust Resonance
its too deflect exesive heat from the exhaust to the cab...they do rust out then rattle...will not hurt the car, you might find inside the car to be a bit warmer +1degree...but its like a $600 pary plus labour.
