I got sent home early today also, what a nightmare i got stuck in a car park, no one would help, managed to get out but the astra was really confused with all the slipping about and i lost TC and ABS both lights on solid this was great when i had to takle a 1mile of untreated roads with 20+ cm of snow.
The lights went off and i got TC and ABS back once i got moving on the motorway.
