Please can someone with ETKA look up the part numbers for the following: - 12volt power supply for 2005 (55 Plate) 8P A3 instead of the cigarette lighter. - aero rear wiper arm for 2009+ A4. - S-Line spoiler for 2005 (55 Plate) 8P A3. I'd like to go and order these tomorrow but unfortunately the parts department are hopeless in my local stealers so would like to have part numbers before I go. Cheers guys!
