Door Lock Actuators Are Self-Cleaning
I thought I would share my experiences with our fabulous door lock actuators.
A few years ago I had the classic symptoms of failing door lock actuators on my passenger side rear door - slow to unlock and lock or outright refusal to move without cycling the locks multiple times. Soon after that I started to have the same symptoms with the passenger side front door as well. I was about to bite the bullet and dive into replacing both passenger side door lock actuators when a thought occurred to me - I was always able to get the door lock actuator to start functioning correctly if I cycled the actuators back and forth many times. What would happen if I started cycling all door locks any time I got into or out of the M5? After making this my routine the passenger side door lock actuators started functioning much better - no more sticking or slow actuation - and were soon functioning as new. They still are today and are the original units installed in my M5.
So my recommendation to all is regularly cycle all four door lock actuators to prolong their life and possibly save one that is starting to fail.
