Just bought an 07 three door S line TDI quattro. Very pleased with it except perhaps the firm ride from the 18" wheels. I was thinking of trying to trade them for smaller diameter wheels with higher profile rubber, but the BBS split rims (I think) look very good, so I'll probably stick with them. I am considering a remap, but I'm wondering if it is worth the additional expense of having the DPF removed, bearing in mind that this is more expensive on a quattro than FWD. Anyone got thoughts on the extra work.
