Notes on initializing power windows (M5 2018-2022)
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2023 BMW M5, 2022 BMW M5, 2021 BMW M5, 2020 BMW M5, and 2019 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Initialization
is performed on the power window switch of the relevant door.
Initialization comprises:
With scaling, the mechanical end stops of the power windows are recorded and stored.
The characteristic curve is learned immediately after standardization.
When the characteristic curve is learned, the mechanical closing forces of the power windows are recorded and stored for correct operation of the crush guard.
Initialization, i.e. scaling and learning of characteristic curve, is performed in a continuous operation.
Initialization comprises:
- Normalization
- Learning characteristic curve

NOTE:
An initialization
must be performed:
- In the event of malfunction, e.g. no onetouch mode, no opening or no convenience function possible.
- After the power windows drive or door module has been replaced.
- After work is carried out on the power windows mechanism.
WARNING:
There is no crush guard during initialization.
Preliminary work needed:
- Vehicle stationary
- Sufficient battery voltage available/connect charger if necessary
- Terminal "15" switched on
- All doors closed
Operating procedure for initialization (manual):
Deleting the initialization:
- Shift side window into lower end position.
- Press and hold switch in "Open one-touch mode" position (second switch position) for between 15 and 25 seconds.
NOTE:
Deletion of initialization was successful if toll function and crush guard have been rendered inoperative.
Performing initialization:
- Shift side window to upper end position
- Pull and hold switch in "Close one-touch mode" (2nd switch position) during the entire process.
NOTE:
Re-initialization was successful if toll function and crush guard function flawlessly.
Alternatively, initialization of the power window regulation can also be carried out via the Service function in ISTA.
