first time working on s4 2013
did bcm2 q5 2011 before threw obd very easy (using AVDI )
this time its a nightmare: connected the avdi via obd it showed it recognized it but didnt read the bcm2 data
so i tried my zed full witch told me to disconnect the bcm2 and reconect (my first mistake was that i didn't disconnect the connectors in order (witch i read some where that its important but only after i got on this crazy ride)
so my first question is: is it possible that i damaged the bcm2 by not disconnecting the brown connector and then the black one?
after i reconnected the bcm2 and nothing worked car stopped communicating threw the OBD
i also tried to connect the wires of the ABPROG and its giving me a Failed READ BCM2
is there a chance to get this done
any help will be appreciated
