I have been searching for the last hour for a DIY on the door lock acuator for the E53.

I found a lot of discussion but no DIY. I checked the articles and no cigar.

I went out this morning 26 degrees and the driver door lock doesn't work with the key fob or the console button. The door unlocks with key, the other 3 unlock fine.

I think this should be an easy fix, right?
