I have messed it up - advise needed

[Helmuth]

Hi all,

seems I have messed my central locking up. What I did: I have mounted this module: http://www.car-solution.de/en/BMW-X5...5-E53-SAV.html which is connected to the iBus and all functions of the module work but:

remote locking/unlocking via key doesn't work any more
mechanical locking of the drivers door doesn't lock the other doors
lower tailgate doesn't open any more
disconnecting the module doesn't change anything

I have already checked fuses 20, 24 and 60 in the front and all fuses rear - they are fine.
Maybe anybody has an idea. With this status I am not able to lock the upper part of the tailgate - not in any way.

HELP !!!!!!!
