Hi Folks

I've got an ageing (1996) Merc 300d estate which has just decided to throw a minor wobbly with the ABS. All seems to work OK but if the speed is increased above about 80mph - on a private road, of course - the ABS warning lamp comes on and won't go off unless the ignition is switched off. It then remains off until the speed goes over 80 mph again. The only other symptom is a couple of light taps under your foot just as the car comes to a halt, ie at about 1mph, or less. Nothing locks up, though.

Have I got a duff wheel speed rotation sensor?

Regardless of that, is there an on-line source of spares anyone can recommend?

First thing I would check is to make sure you have the correct size tyres front and rear.If these check out ok, then a diagnostic will be reqd.Also possible that the stator teeth on the rear drive shafts have corroded away,thus giving a poor signal to the sensor.
