Peugeot 406 2.0 HDI 110 (2002) - Intermittent ABS fault - Grandad Bod

The "ABS Fault" message comes up on my 406 HDI whenever I go round a long, sweeping left hand bend (eg joining the M11 from the M25. If I stop and turn off the ignition then re-start, the fault returns but clears itself after I drive about 50 yards. The fault doesn't come up when I turn left at a junction or roundabout.

As the fault clears it looks as if the sensors etc are OK and the ABS works fine (I tried it on a wet road). Any ideas?

The connectors from the sensors to the loom sometimes give trouble, if you follow the lead from the sensor you will find them, unplug and plug them in a few times with a squirt of WD40 should help.

Otherwise it could be the space between the sensor and reluctor ring changing as a result of movement in the wheel bearing.

Thanks Peter.

I thought it might be a duff wheel bearing but they're all fine, no noticeable play or roughness and the car's recently passed its MOT. Weather and holidays permitting I'll have my head under the wings soon and give the connectors a good clean up.

Hi there

I checked and cleaned all the sensors and on the last wheel (off side front) found the reluctor ring was loose (fault suggested by Honest John). I don't know what's supposed to hold it in position - there's nothing obvious and I wasn't about to take the whole front hub assembly apart to find out as it just looks like poor design.

I put it in about the right position in line with the centre of the sensor and ran a bead of superglue round it - seems to hold fine (maybe that's how Peugeot do it) and no more fault.

Quite likely. Well done anyway.
