S90 Sunroof Initialization Error
Summary of the thread
A 2023 Volvo S90 displayed a 'Sunroof not initialized' error, causing the sunblind to get stuck and the sunroof to become inoperable. The issue arose after recent coding adjustments, although none were directly related to the sunroof. The problem was identified as a corrupted configuration file in the central control module, likely due to the coding. A reset and re-initialization at a workshop resolved the issue.

The coding adjustments covered various modules, but none were directly linked to the sunroof. Based on your experience, do you suspect a specific module or coding parameter? It seems unlikely, but the timing is suspicious.

It's baffling how unrelated coding can cause these issues. I spent weeks troubleshooting. It turned out to be a corrupted configuration file in the central control module after the coding. A reset and re-initialization at the workshop fixed it. I'd suggest visiting a dealer to save diagnostic time.

The workshop visit was helpful. It was a corrupted configuration file in the central control module from the coding, just as you said. Re-initialization cost 75€ and restored everything. Thanks for sharing your experience and saving me a lot of time and money.

Sounds familiar! I had a similar sunroof malfunction on my S90: sunblind issues, complete shutdown of the sunroof system. What coding work was done? Was it related to any sunroof system modules or anything seemingly unrelated?
