XZBMW  Bmw 520D immo problem
Hi all, this car belongs to a friend,  it is intermittent non starter, immo is flashing on the dash, it doesn't even crank, he's checked almost everything,  keys are fine and the car is recognising the keys, if it is left sitting for a while it starts again OK, is immo off possible on this car ? Cheers all.

Thanks, I noticed your response to the other bmw immo thread, if he gets a matching numbers ecu will swapping the eeprom be ok to start the car ?, cheers

If possible full BDM is always prefered (i.e.: Used ecu is tuned etc)

In my opinion, if you are not sure, you should diag ECU and CAS first, specially when car fails to start, and do a test on the comms lines with ISTA for example.
