Left Rear ABS sensor/bearing

tonygreen1966 · Nov 28th, 2019, 20:22

Hi folks

Please see attached jpeg with Vida Dice fault codes. I have Left rear ABS issue. Looks like sensor(0031) and bearing/inductor ring(0032). Had tried SNR bearing before as I was told they were SKF but I now know different. So I'll go for genuine volvo part for bearing anyway.
Think I'll cut and solder on the sensor this time rather than remove seats. Has anyone does this and have any advice. Local Volvo Indie offers the cut and solder route and the seats out route-vastly different prices of course.
The BCM 0136 I've never seen before- can anyone help with that?

Thanks

I’d change the bearing first, clear the codes and then see how it is.

The sensors are simply a coil and very rarely go wrong unless they have been physically damaged.

I've had to change the sensors on both rears, one side twice. Every time it is not the side face of the sensor that faces the inductor wheel that is worn, but the lower face that gets a groove worn in it by rust build up on the driveshaft just under the sensor. There's always loads of rust on the driveshaft just under the sensor- I try to remove most of the rust each time. It's either rust on the driveshaft or debris/stones occasionally getting in there. 3 sensors with the exact same wear. I never go off road.
I'll check out the sensors first as that's easy.
Its a bit coincidental that I get the BCM 0136 at the exact same time as the ABS codes so I think I'll check a common wiring point- perhaps the DEM connector. Anybody any other ideas?

Just to close this off. I changed the sensor only and everything wheel/brake related is now fixed. Been ok now for 4 months.
