Hi
I did buy a Q7 S-line 2009, I have had it for 3 months now and the catalyst broke. I did change them and the car is way smoother and quieter now. My question is whether there is a setting that defines the sound of the exhaust that might have been changed as well. As I used to remember the car had a "nicer" roar coming out of the exhaust even before any issues appeared with the catalyst. So was it just the end of days for the catalyst or is there a setting for the 2009 model "even through VAG" that defines the exhaust sound. I just want to make sure I have my facts straight before I revisit the workshop about this.
Regards
