Could anyone tell me if there is anyway that moisture could trip the abs and associate services warning lights.  Since fitting a new battery everything has been fine,then I washed the car ,since then the warning lights have come on randomly, the battery shows 12.6 volts. This morning all was well on start up,drove about three miles and as I stopped the lights came on, drove off and the lights went out after a few yards ,reversed unto a drive and lights back on. Battery reset and all out except EML .

Hi Mike,

I have not had the experience myself but others have reported that use of a pressure washer can sometimes cause problems associated with the ABS sensors. My understanding is that this is due to water ingress to the cable connectors on the sensors themselves and can be quickly resolved by popping them off and applying some DW40 to the interior and exterior of the connector - making sure to spray the cable sheathing as well - and also the sensor itself. While you're about it, it is also worthwhile checking to see if the ABS sensor head is clean and free of rubbish (they have magnets inside and can gather flakes of metal) and also to check and clean the reluctor ring and remove any heavy 'rust scabs' that may have built up in the slots.

After leaving the DW40 to do its job you will hopefully find the sensors are behaving themselves again but you may need to get hold of a suitable OBD2 code reader to reset the EML.

Hope this helps.

Cheers,

Steve

Jaguar do mention somewhere that pressure washers too close to the car can get water into a few spots on the car.

Thanks both, Although I have not used a pressure washer in this case,I do have the habit of rinsing the wheels with a bucket of water , cleaning the abs sensors will have to be the next job I think ,then give all the wires a smear of WD 40 grease (Liberated from Concorde )

In truth I have been looking for excuses NOT to take the wheels off,but needs must. I used to enjoy whipping the wheels off and on but no more I am afraid.

If you get one of the spray cans of DW40 with the little tube on top you may not need to take the wheels off.

All the best Mike.
