Hi all,

I'm looking to buy an A3 and so am doing as much research as possible - essentially around all the acronyms!
So far I understand about DPF, but have no idea as to what DSL and SS stand for - unfortunately Google is being less than helpful with results and the site search didn't turn up anything either.
If anyone could enlighten me, I'd be very grateful!

Very much looking forward to the new car

Many thanks,
