Model Year 20/21 Cupra Formentor Electrical Issues

[Browter]

I have a 2021 Formentor VZ2 in the UK. Yesterday I went to unlock the boot and it wouldn't power open but it would unlock. I unlocked the car and the driver's side door wouldn't unlock but the passenger side would. When I started the car basically every error message possible came up. It looked like every electrical assistance system had stopped working. There was a message saying brake servo restricted and engine could not go above 3800 RPM.

I drove it home in limp mode and called Cupra breakdown. A VW technician came out and ran diagnostics. They could see the error messages in the logs but there was nothing further coming up at that time.

Has anyone had a similar problem? I've taken it to my local SEAT garage but there's no service department in until next week.

Had it happen once. Similar issue, drivers door would not open using the keyless entry drivers door, but would on the passenger side, I locked and unlocked the car several times using the key fob and after that it worked again. Never happened again since.

Hello, I have 73 plate formentor. Have owned it 4 weeks now, about 2 weeks ago I had a dash cam fitted by halfords. Since then, I've had random error messages popping up but not every day. Including parking brake failure, ACC unavailable, hill hold failure and driver door contact failure. On one occasion, it wouldn't let me open the driver door until I put the physical key in
