E60: Side Window Anti-Trap Function Disabled - easy fix!

This is a very common fault - the chime tells you that 'Side window anti-trap' is disabled and reminds you of it every time you start the car. Each window has height sensors and if something stops it from closing smoothly or it gets stopped half way up then the auto open/close is disabled for that window until reset. Literally anything can cause this, it is way over sensitive, even a bit of dirt or tree-sap in the window runner is more than enough. Sadly, it is not self removing and requires the up and down position for the window to be reset manually, but thankfully this is an easy task and does not require plugging-in to remove the fault message.


* This must be done from the affected window switch itself, not the driver's door panel. *

1. Locate the affected window by testing the 'one-touch' up and down function for each window separately.

2. Open window so it is in the fully down position, release the switch, then press and hold the window-down button for 5 seconds.

3. Close the window so it is in the fully up position in the frame, release the switch, then press and hold the window-up button for 5 seconds.

The window will now auto-open / close again and the message will have gone!

** FOR E39: **
This fix does not apply to E39 models with anti-trap function. The E39 has a crush-sensor in the window frame and will not show a message on the console, so if you have a window that has lost one-touch functionality then the sensor is faulty and will need replacing.


  1. Did not work for my e60. I had to end up testing the window anti-trap on each window and then the control message was replaced with all systems OK.

    1. I'm pretty sure that is what the guide says to do, but I am glad the problem is now resolved :)
