Hi I bought an Audi A4 2.0 TDI avant (2009) in the summer, and now need some new pads/discs. The service book was missing (although Audi confirmed a full service history) and there's no sign of the sticker in the spare wheel well either. Can someone tell me the best way of finding out the discs/pads I need? I have measured the discs and they are about 345mm (front) and 300mm (back) but I dont want to order the wrong ones from an online retailer. I'm even more confused with the various pads that are available! The cars an Sline on 19 inch alloys if thats any use? I can stick up the VIN if thats gonna help anyone? Thanks for any help or advice in advance!
