Sunroof Problems
I've had the issue with the sunroof kicking back when trying to close from wide-open.
Here's what I've observed:
From the wide-open position, when I press the "close" button on the sunroof, it starts to close but then "kicks back" to the wide-open position after about a second of movement.
I can try hitting the button as many times as I'd like, I can try turning the car on and off for various lengths of time--all to no avail.
It only happens when I'm parked.
If this happens, the workaround I've found is to start driving down the street, get it into second gear, and press the close button and magically--it works.
I do not know what's happening, but it seems that I can do nothing when parked. Only when I'm driving will it close, and it has closed every single time i've tried this without fail. Once it has kicked back while parked, it will NEVER close while parked. Strange indeed.
I have done some coding. Specifically coding to allow things like key fob and comfort access to close and open windows/sunroof. I do wonder if this has helped create this issue. I can imagine that there are a bunch of logical conditions that create a different "state" of the car when driving versus being parked, and there could be a conflict between the logical conditions enabled by default versus the ones activated by coding. I'm just guessing.
Any ideas? Anyone else have this problem with or without coding??

Might be an issue with the pinch sensor on the sunroof. Try holding the switch to close for about 30 seconds. On the 2nd gen MINIs anyway, this would override the pinch sensor.
If that doesn't work, you may want to try coding back to stock (right click the ECU and click "Code").
If that doesn't work, you may be setting a service appointment! I had something similar happen to me when I coded my Countryman. It would never close and eventually I took it in and they just reprogrammed the ECU.

Another question -- when you say "right click and code" the ECU, is that really all it takes to go back to stock? Does it change all the coding options back to stock? Thanks a lot for you input!

I'll try holding the switch down for 30 seconds next time this happens. I'm hoping I don't have to loose my coding options. If it is a pinch sensor problem, I guess the sensor could be replaced, or could maybe the sensor threshold be increased by coding a new value?

Yes, to revert back to stock in ESYS, just right click on the ECU (ex: KOMBI or HU_NBT) and in the context menu there is a "Code" option that will revert all settings back to stock, based on the VO. Re-coding doesn't take that much longer if you need to, especially if you've done it before.

I doubt they would have to replace the whole sensor.

P.34 of the 2015 manual
Closing without the pinch protection system
E. g. if there is an external danger, proceed as follows:
1. Press the reel forward beyond the resistance point and hold it. The pinch protection is limited and the glass sunroof reopens slightly if the closing force exceeds a certain margin.
2. Press the reel forward again beyond the resistance point and hold until the glass sunroof closes without jam protection. Make sure that the closing area is clear.
