V70 Central Locking Failure

Sounds frustrating! I had a similar issue with my old Opel Astra. The door wouldn't lock remotely and the alarm kept going off randomly. The mechanic said it was a faulty connection in the door wiring harness, specifically around the door sensor. Is your car alarm also acting up?

Interesting! No, the car alarm isn't going off yet, but I'm leaning towards a wiring issue now. Where exactly was the faulty connection in your Astra? Was it easy to spot?

Okay, no alarm is a bit different, but still sounds like the same family of problems. Honestly, I didn't dig into it myself. The mechanic showed me the damaged plug, but it was buried deep inside the door panel. I would suggest taking it to a workshop and let them have a look at the wiring. They have the right tools and know where to look. Could be the cable or plug connection.

Thanks a lot for the advice! I took it to the workshop as you suggested, and you were spot on – it was indeed a faulty connection in the door wiring harness! Cost me 95€ to get it sorted, but at least it's fixed. Really appreciate your help!
