Just had front diff fitted to my 1999 range rover 4.6 petrol. When I got it back it now makes a bleep from the dash and on the dash it says traction fault and the two warning lights are on. Is it possible the garage may have left some wires disconnected when they were fitting the diff.? If not any advice what may be causing this please. I can not take back to garage as I am in Bulgaria and it is Easter weekend here and will not be able to go back until Wednesday, but it will give me piece of mind if that all it may be. By the way when my diff had gone here in Bulgaria they wonted about 800 pounds for secondhand one, but got one from UK for 100 pound got it brought over by friend for nothing and cost 100 pound to have old one out and other one fitted including oil.
