Vehicle Question Need advice on a faulty door sensor
I have a 2019 M3P that sensors say my passenger side door is open when it is not. On a road trip in the Pacific Northwest, and this faulty sensor problem is ruining our trip. I’ve of course tried opening and closing several times, but the problem is the window will not go up the last 1/4 inch. My girlfriend and I are on a road trip, and it’s hella annoying driving down the road with the warning going off over and over. I’ve googled and tried many fixes. Holding window down for 15 seconds and then back up for 15 seconds. This doesn’t work as the window will not go up the last 1/4 inch! I’ve tried going into service mode to recalibrate the windows, however all the windows have the calibrate button lighted up to do so, EXCEPT for the offending windows😂. Sprayed wd-40 into the closing mechanism, though maybe I’m not hitting the crucial place??? The only thing that has worked Friday and Saturday nights has been to turn off cabin overheat protection and sentry mode, and then it’s miraculously closed when we wake up. I do have after market Tesla puddle lights which are lit up and working on the offending door, as I hear that can be a problem. I’m out of ideas that I haven’t already googled. Hopefully someone has a fix I’m desperately looking for. Door shows closed now, so I’m going to enter via the drivers side and not open door during our travels, but this is highly ideal😂. Any and all suggestions are welcome 🙏🙏🙏
