My ABS light has been on for a couple of weeks now, had it on vagcom and it came up with rear left sensor faulty. So last night I thought I'd try and take it off and give it a bit of clean, got the bolt out but the sensor wouldn't budge. Tried wedging it with screwdriver and soaking it with WD40 but still no joy. Ended up with sensor breaking, is there another way that sensor comes out or is it just stuck in. And will I have to take the rear disc off to get to the rest of the sensor now, and if I am taking the rear disc off will I have to take the bearings out of the old discs as they were re
