hi guys! audi a4 b8 2010 came in none start
found bcm2 had been opened and damged
i managed to read pflash and dflash from the original bcm2 and got a donor with same part number (8k0907064cc)
wrote files to donor
with donor bcm2 in i get fault- control module defective in (46) central conv and central conv check dtc memory in (05) acc/start auth.
key is none smart
with donor in i now have a response from central locking on key and also steering elv locks/unlocks when i put key in(only when i erase faults then all faults in bcm2 are gone . remove battery and put back and then faults reappear and no response from elv untill i clear all faults again )
but no ignition lights no crank
client was trying to fix this car himself and i suspect he tried to fit another ecu set so i also have comp protection fault in bcm1 and cluster but from what ive read this shouldnt stop car from starting
i suspect maybe my original bcm2 data is maybe corrupt?
if anyone could please check for me
also i should add bcm2 donor and original same part number but mcu has different numbers
original d70f3634
donor d70f3381
