I am slightly confussed about the bulb sensors in the B6 A4s, i have found two sets of HID;s from british sellers, one is just a normal kit with slim line ballasts
the other is for CANBUS equipped vehicles, but makes specific mention of bulb checking circuits
Obviously there is quite a difference in price.
I know these are technically illegal for the purposes of MOT, but i have heard of people getting through. Any of you had success at the MOT with these fitted?
