So driving home tonight and I've had several lights come on whilst driving, firstly the abs and esp came on together then a few mins later the heater coil lamp started flashing,, I've recently had new discs and pads on the front and I'm hoping its just a sensor fault or the switch on the break pedal but don't know what to make of the heater coil lamp flashing..car starts and drives perfect but the book says engine management fault!, service immediately!! Anyone shed any light on this for me? Thanks..
