My bogus maintenance plan claims not to cover and dealer wants $1000 to swap out the GM. Is there any special coding I need to know or is this a simple plug n' play module for the on board computer to acknowledge?
Dealer want's $200 for diagnosis, so not sure the risk of buying part at $350 to save $500 is worth it if I can't program it. Any links on how to locate/install in my 02 X5 3.0?
