Not to rain on anyone's parade but my '14 A6 is not happy with the box. I hope you have better luck and can educate me on what to do with it. It definitely increases the diesel noise but I don't really feel much difference in power and mileage never changed. Tried multiple settings. Keeps throwing CEL's for the DPF and NOx. Maybe after the recall of the recall it will work better.
The wife has a Q5 with the box and it loves it. Mileage up 2-3 mpg and no accelerator lag. She wanted it left at factory setting. No change in noise and no codes. Maybe its just my car. I will keep watching this thread. Thanks.
