My EML light has been going on and off for a few months. My mate ran a diagnostics and the result was a EGR valve fault. While the light stayed on the car ran fine. But when the light goes off is when the problems start, at first the car would judder at cruising speed, but was fine under acceleration.
But today as i was driving home from work i came up to a set of traffic lights, so i stopped and the engine cut out. It started straight back up again though
Now everytime the car tries to idle it cuts out.
When i start the car again the revs hover at just over 1000 for about a second then it dies.
Is this a common fault caused by the EGR, or has my car got a more serious/expensive problem?
