Here we have a good used complete matching key set with ecu all all the required modules as well as a METRIC cluster removed from a 2013 Audi S7 with 4.0t engine, This is everything you need to change if you have lost your key or damaged one of the important components. This should fit many 13-15 Audi S7, S6 as well as others. We are also parting out the rest of the car so If there's anything else in particular you need otherwise please send an email so I can list it on ebay for you.
