After a brief drive over some very icey/snowey lanes with the diff lock engaged this evening, I disengaged diff lock (light went out) and then when I set off the lights for the ABS, yellow hill, and TC all lit up and stayed lit until I got home. Engine off for an hour, jumped back in and everything fine. Should I worry or should I ignore? Any helpful suggestions welcome.

I did the search for u......u just have to be patient enough to read everything Land Rover Zone - Search Results

Oooooooh! Seems I'm in a popular predicament with that then. I only picked up the car from the garage on Monday. I think I'll drive it around for a bit over the next few days and if they come back on then at least I can point the garage in the right direction. Many thanks for that.
