I've a 2001 206 1.9 Diesel I've had what can only be described as a miss fire on gentle throttle at just under 2000 rpm for some time now. I've been told it is a possible ECU fault. Yesterday the car started (cold) an run with no problems at first, but later it would not start (warm). It eventually started after about 4 attempts, on the way home the amber engine light kept coming on and off roughly every 30-40 seconds. When I got home I switched off the car and re-started it with no problems. This morning it will not start at all. I've changed the fuel filter and bleed the system and it still wont start (Not even trying). Can anyone help?
