Bought to sort out tailgate lift on 2009 A4 Allroad after being quoted £500 by Audi. Being from a 2015 model I was confident the problem would be fixed and sure enough it was. Word of warning from Audi is to replace in pairs (£1000 easy money??!!). Seeing as I wasnt sure which motor was faulty I replaced both and glad I did as both tested faulty.
