Hi, The engine diagnosis light has suddenly come on, permanently, on my Seat Leon, 1.9 diesel, 04 reg. Everything else seems as normal on the car, it drives the same as ever, no smells, etc. It was serviced, including fuel filter, 1,850 miles ago with no problems.
All fluids and lubricants are as they should be and there doesn't appear to be any odd free wires etc in the engone area. I won't have access to a computer diagnosis for at least two weeks.
Should I be worried, (as in new ECU slit-my-wrists job), or is it liely to be something trivial pertaining to this model of car?
Any helpful suggestions would be greatly appreciated.
