This might be a stupid question, but since im new to the Audi scene i hope you will forgive me. The S Line/S3 etc badges etc; what is the difference in them and what do they stand for? Are they only for the quattro or can other fwd cars have them? Mine for example is a 2002 1.8T Sport and it has a small S line badge under the A3 badge at the rear i didn't put it there it was there when i bought the car. I was under the impression it was because of the spec of the car ie full leather etc am i wrong? Should i take it off?
