hello i have a problem. after been in the snow and bad weather,i now have on dash panel -abs-traction control-hill decent- all 3 lights on.i know that abs and hilldecent are defently not working but not sure about traction cotrol. all fuses look ok.can any members come up with any help.for this would be very helpfull.thank you all.

hi mate they are all linked and the best place to start if not allready done it is disconecct each abs sensor plug in turn (rears just above rear wheel on clip and fronts on a clip inside inner wing) and check for resistance i thimk they should be about 260 ohms but if three are the same and one is different then thats the knackered one. if not could be more serious let me know how you get one. how olds your disco mines a2001 and been told the tax is going up from £210 to £435 in april!!!
