C70 Hall Sensors

Escy · Dec 1st, 2013, 14:14

I've connected up vida on my C70, the "load assistance" feature doesn't work on my car. It's showing up as a hall sensor, number 3. This is located behind the passenger side rear door card (if the car had rear doors). Due to the location i'm speculating it's unlikely to be a wiring fault (as that loom won't be subject to movement like with the other sensors). I'm thinking it's probably the sensor itself.

My question is, how much are these sensors typically from Volvo?

Are all the hall sensors on the C70 roof the same?

Anyone have a part number?

Also, how are they fitted, it wasn't clear on the workshop manual if they had a removable connection or if they needed the loom cut and then re-wired. If I need to rewire, can they be soldered or am I best to use connectors? I have heard that soldering can change the resistance sometimes which can give issues.

Spoken to Volvo, the part number is 1385262. Not cheap at £95 VAT.

Has anyone ever had a good look at one, got any part numbers from the manufacturer?

How did you go with fix? I have same problem including roof not closing after pressing the button and roof failure message displaying. Mine also does not start on first attempt after pressing the button, but it does "fix" itself after about 5 mins.
