Hope you don't mind me jumping on your thread. I'm having a similar problem with my V70, no lights coming on but it feels like the abs is cutting in. It's making the horrible scraping noise on and off and your description of the pedal feeling gritty matches mine. Front drivers side ring is corroded and got a bit better when cleaned up a bit but still there. No codes stored so I think it is as you described and the car is getting the wrong signal for the wheel speed. Only thing that's a bit odd is sometimes I brake and it's not there at all but 90% of the time you can feel and hear it while braking.

Did you manage to change just the ring? 2 local garages are saying it will have to be a replacement cv joint at around £180 as the ring is welded to the end of the joint but the rings are available to buy on their own online so I'm a bit confused.

Thanks
