Thanks 180 :-). I certainly don't want to argue with someone who knows his way around the XF as you do, but I just did a search a bit ago on that Mercedes number and as I stated they showed the door lock module , in the door. I'm not trying to start any chit, just trying to get it straight. :-) Tomorrow after work I will pull my module from behind the dash and TRY to order one accordingly.Thanks again for the help and I will definately post any findings. Norm :-)
