Question could a wheel bearing cause a faulty reading on the ABS system?

[chris_h]

Could it be a wheel sensor?

I have heard of wheel sensors playing up when they get damp in them.  Try resetting the ECU, can you disconnect the battery for twenty minutes on the R to do this?

Sounds strange that they diagnosis the most expensive part on the system first.

We had ABS light come on last year, dealer disconnected (I think LHF) wheel sensor sprayed plug/socket with WD40 and ABS light has only stayed on twice since for about 15min's of driving each time

Give Junks a call / U2U to start with? He may have a few ideas for a good second hand unit?

[a7esk]

Yes that's a good idea any local ones around

[MrSimba]

Is the current one a 2 channel or 4? Definatly not worth putting a 2 channel unit back in whilst it's all apart,

[a7esk]

Yes goes to all 4 and manage to buy one today so next weekend work begins .
This unit does not normally fail was the first for a lotus dealer to see it happen to,
And lotus Engineer has only seen this once so they replaced the complete unit to fix fault as well .

[a7esk]

Almost started but bleeding brakes with ABS unit calls for Lotus bit of kit to make the ABS work to get the air out off the system or can it be done with out this .

[MrSimba]

Bleed brakes then take the car out for a blast activating the ABS a few times & then re-bleed system again, this usually does the trick
