Even if the system is down.. Can't offer any insight but I recently started getting start stop needs service and Park assist temporarily unavailable. It's going to dealer tomorrow. It was fine parking sensors beeping when parking in garage, and the next morning both errors.. SwedeSpeed - Volvo Performance Forum. 4.1M posts 183K members.. The Volvo park assist system is an amazing feature that makes parking much easier. The system makes use of a lot of components, especially sensors. In addition, a PAS can use as many as 12 sensors located in strategic positions around the vehicle. It gives the system an all-around capture of available space and obstacles.
I also get a message that parking assist is temporarily unavailable. They both appeared at the same time. What do these mean? Mechanic's. Mechanic's Assistant: What's the year and model of your Volvo? Customer: 2020 XC 40 Mechanic's Assistant: Is there anything else the Volvo XC 40 Mechanic should know before I connect you? Rest assured that.. I work as a Volvo tech and I have replaced/ repaired several wire harnesses for the parking brake on early S90 and V90 models. The protective tape over the wire harness absorbs sand/ mud and when the suspension is constantly moving it slowly eats away the wire isolation and then water gets in and the wires corrode.
