Hi there have a 51 plate 307 1.6 16v and have had an abs fault for 6 months now I replaced all wheel sensors with no success, cleaned the back plate on the rear wheels and checked the gap, had a guy from Hull with Peugeot Planet call and he said its giving off different voltages and he couldn't fix the fault and finally the car has been in a garage twice on one occasion they said they fixed the fault of which the abs light did stay out but when braking at slow speeds the brake peddle jumped and the brakes sounded like there was no pads left. Eventually the abs light came back on and the braking returned to normal where I can pull up without judder but once again no abs. I have paid out in excess of £300 to mechanics and diagnostic people and still in the same situation where it all began no abs and the orange light lit up. I have on a couple of occasions drove a few miles before the abs light warning comes on but this is very rare. I am not prepared to waste more money paying people who simply don't have a clue what the fault is but still charge me for their services. Any help would be greatly appreciated I have heard there is a Yew Sensor could this cause the fault or could it be the abs pump even through no diagnostics have shown it to be the pump, my gut feeling is it has something to do with the front near side wheel as when i've felt things it seems worse from that wheel.
