Hi everyone and thanks in advance for any help. I recently purchased a 2013 S4 at Copart and initially had a issue with the steering lock module. Code was 02811 I believe. Also had no ignition acc when pushing the key in. I could only manually put the vin in and was able to connect to multiple modules but not the engine and trans.
Anyway I was unable to auto connect with my launch x431 pro. Checked all the fuses and can hear the aux water pump kick on when I opened the door.
I decided to try a used steering lock control module. Initially I gained the ability to auto connect. Then the only lock control module code was for the immo adaptation. I was in the process of pulling the info from the old info with my scanner and it instructed me to remove the connectors from the bcm2 in the trunk. I was doing all this with the forways on to keep it all awake.
When I unplugged the bcm2 for 5 seconds and hooked it back up I lost the rear flashers and lost connection to the module 05.
Of course the programing then failed and it wiped the long coding.... I did screen shot it before so I have it but it won't go in says trans not in neutral ....
I fear that I was not to unplug all the plugs from the BCM2?
I think I blanked the bmc2 it and am not sure what to try now?
Any help would be appreciated
Thanks
SG
