the abs and traction control light comes on and then gos off if you turn the ignition on and off wheel bearing fault.you can hear the bearing but i can not tell which wheel it is i have felt for play on each wheel but all seem ok i dont whant to spend 70 quid at the stealers to have tech2 for a job i can do myself i only whant to know which wheel it is . i have measured the resistance of the sensors by using a ohms meters and spinning each wheel to see if the resistance changes and it does the sensors are about 1500ohms but the drivers side is only about 400 ohms do you think that this is the faulty bearing, air gap, any help or your thoughts would be great and how long do vou think i can carry on driving the car without the wheel falling off. ps all sensor leads seem to be intact.
