ashmk3 0 Posted June 13, 2012 Report Share Posted June 13, 2012 How close should the rear sensors be to the ring. As my rear right sensor keeps cropping up even after a new sensor. But when I removed the old one it was almost touching and so is the new one but i can't see anyway to adjust it. The fronts are about 3-4mm away but the rear right you can hardly see light through the gap. And I couldn't get the left side shield off to have a look in comparison. If any one has a picture that would be great. Link to post Share on other sites
cabrioman 6 Posted June 13, 2012 Report Share Posted June 13, 2012 there should be an air gap between the sensor and pick up ring but don't think the distance matters (could be wrong) as long as it not touching and not miles away should be OK .... have you tried swapping the wires under the seats see if the fault moves to the other side if it don`t you could have a wiring fault if it don`t then the pick up could be faulty ... have you had the rear discs changed recently ????

russj249 2 Posted June 13, 2012 Report Share Posted June 13, 2012 Autodata says 'airgap not specified - no adjustment possible'As Tony says, maybe drop the rear discs off and check that the abs ring has been put on before the rubber seal for the wheel bearing.. it might have been put on afterwards so it sticks out too far. If the abs ring sits on top of the rubber seal or is loose its not right.. it should be put on first, then I use a 36mm ish socket and mallet to press the rubber seal in afterwards.

ashmk3 0 Posted June 13, 2012 Author Report Share Posted June 13, 2012 Funny you mention discs when I got the car the handbrake wasnt engaging on one side so I removed the caliper and freed the piston up and the handbrake mech. Now that works perfect but I did notice that the abs ring was able to move without much force around where it sits and I can move it back and forth.This may be the issue then as when I switch wires over it does indeed change sides. I have just finished work so will have a look won't I need new bearings if I take the disc off? Link to post Share on other sites
ashmk3 0 Posted June 13, 2012 Author Report Share Posted June 13, 2012 Just taken the wheel off and looked behind the disc and there was a magnet stuck to the inside shoulder of the disc and looks like that may be why I was getting the like coming on every now and again rather than all the time. As it looks like it has got stuck to the new sensor and dragged on the ring. Link to post Share on other sites
cabrioman 6 Posted June 13, 2012 Report Share Posted June 13, 2012 yeah if you can move the pick up ring then that more than likely the fault, take it off try and squeeze it together a bit then push it back on the disc, if it difficult to get back on then it should be OK and wont slip ....

ashmk3 0 Posted June 13, 2012 Author Report Share Posted June 13, 2012 Just took it out for a drive and it came on as I pulled up so it's not the magnet that was left from the last sensor. Will try the ring and give it a wire brush too. Link to post Share on other sites
ashmk3 0 Posted June 13, 2012 Author Report Share Posted June 13, 2012 Right disc all off and sensor and ring cleaned cleared fault went for a drive and on comes the light. And Craggsy did say that his was always the rear right so it looks like a new module as the one I have was his old one. So if anyone has one let me know. Link to post Share on other sites
