BCM-0042 Wheel sensor right rear. Mechanical fault

[colinbos]

Happy New year chaps.

2008 XC90 2.4 SE Manual.

Im 'front' loading this thread - the car is going to the mechanic on Monday. I don't think its a huge issue.

I've had the yellow ABS/Anti Skid service warning triangle and a 2nd dash warning message of Brake Assist service required for a week or more now.

DTC shows, BCM-0042 Wheel sensor right rear. Mechanical fault.

Cleared it, washed the sensor areas on all 4 wheels, still appears.

I have reluctor rings which I bought for the front... BUT, are the the same size for the rears ?

Anyone else had any experience of this code ?

Cheers

From VADIS:

On the front wheels, the pulse wheel is pressed onto the outer constant velocity joint and the wheel sensors are located radially in the shaft housing relative to the pulse wheel. On the rear wheels, the pulse wheel is pressed onto the hub and the wheel sensors are located axially relative to the pulse wheel. The rear pulse wheels can be replaced. Both the front and rear pulse wheels have 48 teeth. In the event of a fault in any of the wheel sensors the following systems will be disengaged or will not engage.

I don't know if they are the same size.

This eBay ad seems to show that the rear rings look very different from the front.
