Yesterday at one point my DSC light stuck on, I managed to reset it by switching off ignition and then using the DSC switch to toggle it off. I thought that this was a one off problem, but today after washing the car, (maybe a clue there), the DSC and the Tyre Defect lights are on and won't reset. Checked tyre pressures and all OK. Anyone else seen this fault ? - looks like water got in somewhere it shouldn't have.
