So yesterday fitted a new BCM or "convenience " module as VW call it , the original one went to lunch and as recently posted we lost tail lights and interior lights .I did manage a temporary work around to restore tail lights but wanted the new module to keep things correct . Any way my German tech place firstly copied all the codes from the old module then fitted the new one and transferred the codes back onto the new module , I did,t bother to check when I picked it up but later noticed the doors would not lock unlock via the remote keys but the central locks do work from the key in the door . I read my manual where it tells of resynchronizing the remotes if this issue occurs but I,m buggered if VW,s wording in the manual makes sense . Its says press the unlock button on the remote while standing close to the vehicle then lock the van with the key in drivers door , next it says to switch on the ignition and that's it . Ok so how do you switch on the ignition during the process if the damn door is locked ? It makes no sense as it does not outline the actual steps clearly . Now as a matter of interest was even after fitting the new module the interior lights still weren,t working , the tech found that there was no power to connection pin 66 and it was suspect of an open circuit between Fuse 17 and pin 66 . Now I,m no rocket scientist but how can a wire suddenly not work when the time before the lights were lost it was obviously working fine . So another work around was to use a jumper wire from a constant supply at the same connector on the module and connect to the wire on Pin 66 using a fuse in the wire for protection . I just don,t get why this wire suddenly stopped supplying power from the fuse box to the connector . PS in case anyone can clarify the instructions for the key it is on the bottom of page 39 in your manual .
