Hi guys new member here (hello) I'm currently on the lookout for an A4 estate (diesel). I've currently got my sights set on an 06 a4 2.0 tdi avant s-line. It's the 1986cc which afaik is the 140bhp model? and has 55,000 miles on the clock. This is where you guys come in.. are there any common faults for me to look out for on this car? Service history musts to look out for maybe? Hope you guys can help, I've been wanting to join the audi crew for a while now!
