Fuzzy dice or LED bulbs are not a repair

Possibly helpful videos.

I think I know how to do it (I probably lost the instructions that I printed) and just needed to buy some long Torx drivers, which I now have.

Here's a solution: I bought a used lock actuator module on eBay. Came from an 07 E63 (so it has the correct amount of horsepower).

Only $47 shipped saving like $250. I think that's worth a try.

Guess I could have done a better job searching the first time.

Possible no parts required fix though it's definitely jury rigged. But it does make me glad I didn't drop $300 on a new module. This is probably what's wrong with mine.

I manually locked the latch and it opens when I pull the cable. So it would appear that this should fix my issue. Just need to pull the door panel and operate on it. Fishing the old one out and this one in is a little tricky due to the size of it and the access.

And it's done!!!

Let's call it maybe 3 hours total taking my time to look at stuff. It's definitely a bit involved but like with anything else you go step by step. I used WIS instructions do to it.

Once I got the latch module out I compared part numbers to the used one from an 09 E63. The last 3 numbers were different so I got worried.

But I believe the last 3 are just some kind of revision code because the main part number is the same. So with that out of the way I began the reinstallation process. It is, after all, the reverse of removal. Actually it went together easier than it came apart.

Random pictures along the way.

Going back together.

Before I put the door panel on I wanted to try the latch. I closed the door and pressed the lock button on the handle. Nothing happened. Tried on the front. Nothing. I noticed a red, angry warning on the dash. It said all the doors aren't closed. It turns out the door panel is what presses the door switch so because I hadn't put the door panel on, the switch wasn't getting pressed. Ha.

So I held the door switch closed and pressed the lock button on the handle. All doors locked! And when I pulled the handle all doors unlocked. Awesome. I will have Ian officially test later but all seems to be fixed. Happy to have this done.

Ian tested. He opened the door from the inside like 3 or 4 times in a row. Fixed forever!
