The error doesn't specify a particular door, unfortunately. It just mentions a general malfunction in the door electronics. Did you have any luck diagnosing the problem yourself, or did you take it straight to a workshop?

I tried a few basic things, but eventually, I took it in. Turned out to be a faulty connection in the door wiring harness. Best to get it checked properly before you start replacing parts.

Thanks for the insight. I had it checked, and you were spot on, it was a defective plug connection in the door. Repair cost me 95€. Appreciate the help!

That sounds familiar. I had a similar problem with my 2018 Opel Insignia. The door handle sensor went haywire. Does the error message point to a specific door or sensor?
