Door handle not lighting up/comfort access not working

[TheRealMoleman]

Wasn’t sure how to title this post, hope it’s sufficient.

So I bought a 2015 BMW 750Li (F02) a couple weeks back, and one of the (minor) issues I’ve discovered is that the LED courtesy light inside the exterior door handle of the left rear passenger does not light up. Additionally, the comfort lock/unlock feature doesn’t work on that door, either (it does on the other three doors however.) Also, the courtesy LED that shows on the ground (can’t remember what that’s called exactly) only lights up intermittently, usually not lighting at all. I suspect all three of these issues are obviously related. 🤷‍♂️

Any idea where I should start trouble-shooting this issue? 🤔 The BMW dealership wanted $259 just to *look* at it. 😲

I’m in New Port Richey, FL, so if anyone knows a shop (or even an individual) local to me I’d be happy to compensate them for helping me to address this issue. I’m a fully disabled vet so I can’t really tear things apart or bend over/get on the ground for very long. 😩

I have an issue with my driver's comfort access door handle. I should have thought this through more before just picking up a used handle on eBay. But I saw an video that had luck with a $40 one from eBay. I should have went that route to see if it fixed my problem. $40 is cheap vs diagnostic fees or a used one that might not solve the issue. If it did solve the issue, buy the used one in the right color. There's always a small chance the $40 part is complete crap, so there's some risk. Still cheap.

You only need 2 tools and some patience with the wire connectors.

I did, and that mostly fixed my issue. The convenience light at the bottom still doesn’t come on 100% of the time when the door is open, but that’s a minor issue I can deal with later. 🤷‍♂️
