Thalia Sunroof Initialization Issue

Sounds familiar. Had a similar problem with my old BMW after ECU work. Was it full coding, or just tweaks? Does the error say anything besides 'not initialized'?

Just tweaks to the lights. The error is vague, only 'sunroof not initialized'. Is there a reset button?

No secret button, unfortunately. If it happened after coding, and the error's vague, it points to a software glitch. I had to take mine to a workshop to get it sorted.

Ugh, that's what I was afraid of. Local shop confirmed your suspicion. Sunroof needed reinitialization after the coding issue. Cost me 75€, but it's working again. Thanks!
