Was out in the Synergie last week. Drove it about thirty miles at a good speed in heavy rain, stopped it outside daughters house, came back out after ten minutes, turned the key and it wouldn't start. Cranked over ok, wanted to go, but just wouldn't. Coughed occasionally as if it wanted to but would not go. Sounded like a fuel problem. Breakdown service thought it was the glowplugs not heating but as I had had no previous hints they weren't I don't think that is a possibility, and the weather was quite mild anyway. Got towed to a garage, who after three days are still scratching their heads over it. Their fault tracing device throws up a number of options apparently (but not the glowplugs) and they are struggling. The latest offering is that it might be the fuel pump. Anybody had a similar problem, and if so, what was the culprit. The van has been performing faultlessly up to this minute and mucked up a days shopping to France, so not very pleased at the moment.
