Hi, when I brought my A4 a few months back I ended up being given two service record books, one for my car and one for GF55 SXT, I asked the person who I brought the car from and he had no idea who's it was. If this is your car (or know the present owner) and you want it please PM me and we can get it in the post. I also have the Audi Navigation System Plus (RNS-E) Operating instructions manual too (Has a serial number and pin in it). If there are no takers the Nav operating manual will go on a popular bidding website and the service one in the bin. Cheers.
