2008-2010 Audi TT Quattro Haldex Rear Differential Assembly. This assembly will ONLY fit the AWD Quattro models. Will NOT fit FWD base models. This was removed from a 2009 Audi TT Quattro that only had 65k miles and was equipped with the 3.2l VR6 and the S-tronic DSG transmission. The differential is stamped with the "KMC" code. Please verify your existing unit is also stamped with KMC on the underside prior to purchase. This unit will ONLY work with vehicles that also came equipped with the KMC unit. Includes the differential, housing, haled control module and input stub shaft as shown. Differential is in good working condition, fully tested prior to removal from the vehicle. Differential made no odd noises or grinding. We did notice some fluid seeping from the axle seals. These seals will need to be replace prior to installation. Differential has some typical cosmetic wear and discoloration throughout. You will need to reuse some of your existing hardware for installation.
