Q5 BCM2 8KO907064KH problem
Hi guys , working on a 2016 flooded Audi Q5 keyless.

I replaced all flooded modules including BCM2 (by swapping Renesas D70F3634 /1510KE428) .

I have can comunication with all modules i replaced but the car would not turn KL15 on and i have on dash error " Ignition lock faulty" (the car does not have ESL and i also replaced ignition with same partnumber )

and on diagnostics i have the following error on BCM2 : " 00003-014 Defective"

Remote control works but still car will not turn KL15 on.As far as i know this might have to do with corrupted SW inside BCM.


I will gen Poldiag in order to try to recover SW but meanwhile i wanted some opinions from you guys.


Thank you
