V Klasse parking assist malfunction

Parking assist giving you grief? I've got a V Klasse too, and I remember something similar. Is it completely dead, like no beeps when you put it in reverse or approach an obstacle? Did you check the fuses? It seems basic, but I chased a similar problem before realizing a fuse had blown. Also, have you looked at the sensors themselves? Sometimes they get caked in dirt and grime, which messes with their readings. Which sensors did the error memory point towards?

Thanks for the quick reply. Yes, it's completely dead, no beeps. I did check the fuses, all seem to be okay. I visually inspected the sensors, they appear clean, but I haven't tested them individually. When you had a similar issue, did the error memory specifically point to a sensor, or was it more of a general parking assist fault message?

Right, completely dead, sounds familiar. Mine was giving a general error, didn't pinpoint a specific sensor. I messed about checking wiring looms, but honestly, after a while I gave in and took it to a workshop. They diagnosed it as a corroded connector on one of the sensors. The connector was replaced. If you've checked the obvious things, and the error is still there, it might be worth getting it properly diagnosed before you start replacing parts.

Appreciate the insights. Sounds like a corroded connector is a common issue. I will take it to the workshop next week. They quoted me around 95€ for checking the cables and connectors, which seems reasonable, so I'll get them to investigate. Thanks again for sharing your experience!
