Not sure if this belongs in this thread but it is TT related so I thought I would give it a shot. I have a 2001 225 TT with an AMU ecu part number ending in 018AT. The car does not have an immobilizer, I know this because I installed a remote starter and it did not need an immobilizer bypass to work. This question is 2 fold:
1. Will an AMU ecu whose part number ends in 018K work with my car which has an 018AT
2. The 018K has an immobilizer built in, will I need to have this bypassed or will I be fine since currently my car does not have an immobilizer at all?
