Master sunroof not initialized

I've got a Master too and this sounds vaguely familiar. Was the coding specifically related to the sunroof control, or something else entirely? I'm just trying to remember if I messed with something similar before I experienced issues...

The coding wasn't directly for the sunroof; it was for some comfort settings. However, I've been reading that it might have inadvertently affected the sunroof module. Did your symptoms include the sunblind getting completely stuck?

Yeah, the sunblind issue definitely rings a bell. I remember it being stuck solid. Honestly, I never figured out the root cause myself. I ended up taking it to a workshop to have it diagnosed. Given the coding you did, it's possibly worth investigating that area or just going straight to a mechanic to get it sorted out.

Thanks for confirming. Knowing someone else had a similar issue points me in the right direction. I had it checked and re-initialized the sunroof module. Coding had messed it up. Cost me 75€ to fix. I appreciate the help!
