Hello, After i've retrofited Bi-xenon with lamp washers warlier last year now i want to install the auto-leveling sensors in order to haev the full system nicely retrofited. I found a great deal at a german seller, he sells me the two sensors for about 50 euros, my issue is that the part numbers for the two sensors appear to only fit Audi A3/TT starting with 2009, does anyone know if they will fit my2005 Audi A3? The part numbers are: 8J0941274E and 8J0941273G. Also what other gear do i need to retrofit it besides the usual harness and control unit. Thank you!
