The dealership replaced my battery on my F26, and now the sunroof no longer performs the one-touch open or close when fully pressed. I looked online and found that recalibrating it by holding the switch in the vent position should fix it. The issue is that mine begins the cycle, opens most of the way, then stops. I’ve tried it a dozen different ways, but it never finishes the cycle. I’ve attached a photo showing how far it opens during the recalibration attempt.

Does anyone have any ideas, or should I bring it back to the dealership?

After many attempts to fix it myself, I ultimately brought it to the dealership. For anybody who finds these posts, some notes on what they said:

- They said they tried the recalibration step with the tilt, and it didn't help
- They then said there was another calibration from the diagnostic mode that didn't fix it.
- They finally did fix it, and in the video they sent, the repair person stated that the FZD module was not initialized. They did that, and it seems to have fixed the issue.

The good news is they didn't charge me for the diagnostic or the fix.

Not sure if any of this will help since I have no idea if anybody but the dealer can initialize an FZD module, but I thought it was worth sharing since I tried for many hours to fix it myself before giving up.
