Just bought a 2000 TD5 auto, 138k on the clock, driving it to my work to check it over pulled up to a junction and m and s lights started flashing and engine light came, no throttle response at all, engine idling fine. Switched off a couple of times still on, switched off for a bit longer and it was fine, drove it for quite a distance with no issues, gave the car a quick check over at work, on the drive home exactly the same happened, once switched off was fine, seems to be heat related. I have looked at other posts but none seemed to be while driving along. Any ideas please. Simon
