Hi, i have a 2002 laguna 1.9dci. over the weekend it had an intermittent fault with the glow plug/ computer warning light coming on and then going into limp mode. when it was off the car was running perfectly however now the light is on constantly and in limp mode. I booked it into renault at wakefield for a diagnostic check, they said it showed code df125 which is an analogue-digital fault. they had never seen this fault before so contacted technical department who said it is the injection computer and needs replacing at a cost of £880. does anyone know if this sounds right or if theres a cheaper fix. i know its a long shot but ive now got the dilemma that cars prob not worth much more than that.
