Eseries Keyless Access Door Handle Error

Sounds familiar. Had a similar problem with my old Opel Astra. The central locking went haywire. Have you checked the door switch?

You mean the door switch in the door jamb? What did you find when your Astra had the same issue?

Yeah, that's the one. In my case it was easier to bring the car to the workshop, as it was tricky to get to the faulty part. Best if you have it checked.

Thanks for the tip! I looked at the wiring, and the cable was faulty. Replaced it for 95€. Everything is working again.
