2012 ML 350 (W166). *Sunroof (or sliding roof) will open smoothly and then close smoothly using the selector switch, but as soon as it fully closes, the rear edge opens to the tilt position. *Does this every time. *You can coax it down a tiny bit at a time, but it is very difficult to get it perfectly closed (no wind noise or water entry). *If you go too far, it tilts fully open again.

I have looked at reset procedures in other threads and in Youtubes, but the only ones I can find are for other models that have a 4 function switch (push up to tilt up / pull down to lower from tilt /push rearward to open fully towards rear / push forward to close). *This model has only a 3 position switch (push up to tilt up / pull down to lower from tilt -- also pull down to close from rear open position / push rearward to open fully). *The owners manual is no help.

​​​​​​​Anyone have the same problem and know how to fix it?
