Today I was driving the car as normal and the esp light came on. I tried to use the indicators and the green arrow just stayed on but they wouldnt work. My climate control was flashing going on and off and windows wouldnt work. I turned the car off then it was ok. But I was driving along and it happened again. Now the central locking wont work the light work on the car but nothing comes on the dash now. Any suggestions would be a great help. Would this be big money to fix??
