V60 Parking Aid Fault

I had a similar issue with my V60. Parking assistant without function, and a corresponding error code. Have you checked the wiring harnesses and connectors to the sensors themselves? Especially around the rear bumper – road spray can get in there and corrode the pins. That's where I'd start before digging deeper.

Good shout. I'll check the harnesses. Is it likely to be the sensor wiring rather than the sensors themselves? I'd assumed a faulty sensor would flag up a specific sensor error, or is it more subtle than that?

In my case, it was the wiring. A broken wire can cause a complete system failure. The control module detects the lack of signal from all the sensors, and shuts down the whole system. Worth a shot checking the connectors before condemning the sensors. I was quoted 95€ for diagnosis, which seemed reasonable if I couldn't fix it myself.

Thanks for the advice. It was indeed a corroded connector on one of the rear sensors. Cleaned it up, applied some dielectric grease, and it's working perfectly now. Appreciate the help!
