If your BMW 5 Series (F10/F11/F18, 2010–2017) has the electric glass sunroof and its one-touch open/tilt has stopped working — typically after a battery disconnection, a flat battery or a fuse change — the roof needs re-initialising (BMW calls it normalising) so it relearns its end positions. It is a quick no-tools job from the cabin. This guide shows how.

Why the Sunroof Needs Re-initialising
The sunroof motor stores its closed, tilted and open positions so the one-touch and anti-trap (pinch protection) functions work. Losing power clears that memory — the roof still moves while you hold the switch, but automatic operation stops until it is re-taught.
How to Re-initialise (Normalise) the F10 Sunroof
Do this with the ignition on (engine can be off):
- Turn the ignition on.
- Operate the switch to bring the roof to the fully closed position.
- Press and hold the switch in the close/tilt-up direction (at the maximum position) for around 20–30 seconds. The roof will tilt and move slightly as it relearns.
- Keep holding until the roof completes its cycle and stops moving.
- Release the switch and test the one-touch function — a single press should now tilt/open the roof automatically.
If It Still Won’t Operate Automatically
- Repeat the procedure — the hold must be long enough for the roof to run the full normalisation cycle.
- Let the cycle finish — don’t release the switch until the roof has stopped on its own.
- This is the step BMW lists after reconnecting the battery, so run it alongside the window initialise.
Frequently Asked Questions
Why did my sunroof stop auto-opening after the battery was off?
Disconnecting the battery wipes the roof’s stored end positions, so one-touch and anti-trap switch off until you normalise it with the routine above.
Do I need any tools?
No — just the overhead switch and the ignition on.
The roof reverses when closing — what’s wrong?
That’s the anti-trap protection reacting because the limits aren’t learned. Re-run the normalisation and make sure nothing is obstructing the channel.
My F10 doesn’t have a sunroof — does this matter?
No — only cars with the electric glass roof need this step. If yours has none, skip it.
