Hi Gareth
Apologies for the bad punctuation and grammar as Im typing away on my phone. Reading from the log book it describes the car as an A4 SE S LINE QUATTRO. That you would believe would be the end of it. I contacted Audi spec check again and they have stated the car is as described using reg and vin number but also then added ( Special Edition). This is what is listed on their system. So being still rather confused I continued my search. A few people on the Audi sport forum believe the SE part refers to Standard Equipment. The other half drives a little Skoda citigo sport and it has all the bells and whistles. Yet while shopping for one the SE citigo was the second from bottom in terms of specification. This appears to be the same with the Seat mii which is an identical car. Its a minefield of different terminology set to confuse I guess. So looking again I found this little paragraph on wikipedia.
In 2007 Audi introduced a version of the B7 named the 'Special Edition', which built on the S-Line specification and also included the black optics pack, the RS4 style 8J X 18 '7-arm double spoke' design alloy wheels, Two-tone Graphite/Black Volterra leather, 3-spoke sports leather/Alcantara multi-function steering wheel with gear knob and hand brake handle in Alcantara with silver stitching, ventilated cross-drilled front disc-brakes, black tailpipes and black roof rails (avant model only). It also had a power increase of 20PS, giving an output of 220PS on the 2.0T model.
All of this apart from the Avant model roof rails I have, so ties in with what Audi are stating. Again I appreciate all your information and help
