Hi Philip, it is unacceptable for your dealer not to treat this as urgent, on the basis that illumination of the EML is an MOT Failure - classed as a "Major Fault". Technically, your car falls into that category and MUST be given some urgency by the supplying dealer. I would avoid plugging an OBD Reader into the car to avoid any potential accusation that you created the fault and, also, I'd worry about Warranty implications. I'd give the Dealer grief - tell them you refuse to drive the car with a Major Fault and ask for emergency recovery to their Workshop. If no joy, I'd speak to the Finance Company for help!Hope you get it sorted.
