Just had Geoffrey checked out for the ABS error I've had for a while and the software used says is a missing tooth on the sensor ring.

Any idea how much that should cost to sort out?

 

I think as far as weather it's front or rear will have an impact on labor costs ,it would be a couple of hours work . but as far as a rear reluctor ring it self goes ,is surprisingly well priced , not sure about the front , qualety after market one on eBay here ,
