Hi,
I have a 2020 DS7 Crossback.
I keep waking to find that, during the night, the rear drivers side (Im in the UK) window has opened.
This is after locking it and ensuring that all windows are closed. The car remains locked and all of the other windows remain closed.
Any clues ?
Bit of an odd one this .
Is it fully open ?
I know the windows can be operated off the key fob, but I would imagine if there was somehow a signal being sent from the fob to the car it would effect all windows not just the one.
Perhaps try locking everything up and removing the fob further away from the car or remove the battery just to see if the issue resolves.
Does this happen only in the rain ?
Maybe water getting into the electrics on that door ?
Perhaps the window switch on the door is faulty/sticky causing it to operate, or the one that’s one the drivers door for the rear door.
Is it only at night ?
Very odd.
In my old Audi TT (2 doors car) that was an indication of a low battery voltage that requires replacement. Not sure if this is a similar function.
Thanks for the responses. I’m going to test and change batteries and check switches. It has not happened for a few days now (It hasn’t been raining either). So Ill see if anything happens next time it rains.
Has not happened since changing batteries and checking the switch, so thanks for the advice.
