hi, im collecting all the parts together to fit an rns-d into my 2001 s3, the only part im having trouble with is the tmc tuner there are a couple on ebay, but one is from an a8 and the other doesnt say what model car its for, will any tmc tuner fit my car or will i need one specifically for an s3, any help would be appreciated, thanks
