Hi mate, did you figure out what it was? I’ve a 2010 discovery 4 hse tdv6, just this morning I’ve had the exact same message, goes off when I restart… sometimes comes on when I start… never had this issue before, was only dropping the kids off at school, the car is high mileage but had no issues with engine or gearbox before… can’t afford a heafty bill right now as lost my business in lockdown and been holding on to my car as I love the stupid thing, got handbrake disengaged at the moment as the gears need rebuilding in the hand brake module which I’ve got the parts few days ago
