    Default AUDI A5/S5 bcm 2

    car doesnt want to accept the key in the slot. all i get is 3 times click and error message in the cluster.
    I changed key reader, so I figured it is bcm2 problem. or could it be esl ?
    I have read flash and dataflash from original bcm2 and from donor bcm2
    8k0906064cq are both
    I tried to write original dataflash to donor bcm2, but with the same result...3 times click...
    any help would be much appreciated.

    thanks,

    Would help to get what was the original problem and what was done to reach this point.

    hi,

    owner crashed the car, with almost no damage. just front bumper and right wing.
    from that point on car does not start. 3 clicks only and message in dashboard " do not drive the car.steering defective"
    in bcm2 modul is error message "control module defective"

    br,
