Hi all. Today came back from day out . Not in my car a C350E and the sunroof and windows where open.
This is the 3rd time in as many weeks. Any ideas?
 
Many car have a feature that opens all the windows and sunroof if you press and hold unlock.
If yours does this then it could be a failing key.
 
I might be talking out of my hat here (nothing new there then) Did certain MB's have a feature when internal cabin temp went WAY high the sunroof and windows would open up a bit automatically as a safety feature. If so there could be a fault in the sensor 🤷‍♂️

Or am I dreaming again ? 🤔.
