I have a 2005 reg A3, the engine code is BKD and it had the DSG gearbox (incase that makes a difference). My problem is that all Audi garages and even the Audi Customer services only have record of a 'B' revision head as the newest. My car already had a 'B' on it, and if a C does exist, i'd rather be replacing it with that. I also asked Audi to search on their system for that part number but ending with a 'C' and they told me that its an invalid part number.
Could it be that the C head isn't compatable with all BKD engines?
If not, which Audi garages are aware of the newest C revision as I want to order one.
