I've seen various testimonials on non-Audi sites for BG44K as a way to 
clean up carbon deposits and address the associated high NOx readings in 
emissions tests. If your car has high mileage (like your typical UrS), 
this product may help. Turbo Ovlov owners seem especially smitten. No 
experience personally, but I may give it a try. Website has list of dealers:
