We replace the engine on a 2002 745i BMW and we took it to the dealership and they can't make the cart start:
Here is the work that was done on the car:
1. Engine was replace with used engine
2. Engine wire harness was replaced new
3. Intake replaced with new intake
Here is what the dealer has done to the car:
1. Got rid of all the codes
2. Check all the recalls this car had
3. Made sure the DME was working, they put mine into another 745i bmw and it started.
