It’s not often that I laugh out loud at P-H posts, but I did when I saw this one. I will be forwarding the link to a few others, for sure…
But on a more serious note, my ageing silver Citroen (diesel HDi) is not enjoying the -20s we are getting in Nancroix overnight. Yesterday it started OK (coughs a few times when it’s below about -8) but stopped after about 30 secs. Would only run for 4-5 seconds at a time whenever you re-started it. I had the same problem about 6 years ago in La Plagne and put it down to a dodgy batch of diesel I’d bought in Intermarche in Albertville. Co-incidentally, the current tankful is also from Albertville, but this time Casino. (If it’s anything like London, it’s probably the same depot / distributor for all the local filling stations).
I tried rolling it downhill to see if it would stay running if switched on and engaged in gear, but not much luck. Eventually after a few kilometers and a few more attempts at re-start, it got going and stayed going.
Given that the injection warning light stayed on thereafter, I put yesterday’s incident down to ‘cheap’ diesel again, waxing/gelling in the system. In Bourgoin-J I finally got some anti-gelling additive (three previous garages I tried had run out, I guess because of demand caused by the current cold weather) and finally the injection warning light went out and it seemed to run a bit more happily.
BUT… does anyone have any tips for preventing this sort of trouble (serious ones please, no wood-burning stoves)? Heated garage is not an option. I’ve heard that adding a couple of pints of petrol to each tankful of diesel is one fix. I’m sure I can keep buying additive (when available) but that’s expensive and I can’t predict the weather (ie when to treat the tankful of fuel and when not to bother). Are other cars less prone to gelling (eg maybe thay have a heating coil around the fuel line in advance of the injection system)?
