I want your faulty electronics
you got the fixed key or flip key?
When you lock the car with the key, does the pump carry on a bit longer than normal?
I got any issue where mine randomly locks and unlocks. That only happens If i plug the rear boot latch in. with that unplugged it all works fine.
It might that causing your issue.
I also had the passenger window opening randomly. replacing the remote battery and recodding worked fine.
