Re: 156 2.4 JTD Eratic Idle and stalling when cold
Mines had the glowplug light on since I bought the car, april 2006. Did all last winter with no problem. I don't think it is the actual glowplugs that have failed, otherwise it wouldn't have started so perfectly and ran absolutely fine from cold, if it was on 3 or 4 cylinders?
Funnily enough, when I bought it the light ALWAYS came on, even if it was restarted after, say fuelling, when the engine was still warm.
Now though, the glowplug light doesn't always come on. Only just started doing it a few months ago.
