Hi, Sorry if I've posted this in the wrong section, Was driving to work last night, glow plug warning light starts flashing, car goes into limp mode, stop at traffic light, switch engine off/on, light gone, ?odd smell from exhaust. Drove home this morning with no warning lights, no noticeable issue, not sure if I had a little less power in high revs or if I was imagining things. This something to worry about? Anyone had a similar issue with a known cause? Seen very mixed and unhelpful results online. Just a bit of info, for the last 2 months car has only been driven short 3 mile journeys, had no long runs for that duration, not sure if that would affect things Thanks for any help chaps.
