Preheating a misconstruction? Dear community! I had now some times the problem that the preheating started (dirketstart/timer), but it did not ignite. A mistake was written in the memory, which was then extinguished with mine. It was nice cold, but can it be that lt. A friendly the preheating only works up to approx. -17 degrees, because then it is too cold for a ignition? Somehow paradox! I think back to my trucker times, In Belarus everything went at -30 degrees also. OK, was something more special diesel, but nevertheless! Here also OMV winter diesel, which goes up to -22 degrees (acc. to OMV) in the tank! And at the sale of the € 1233,84 expensive heating nobody told me that this then from 17°C does not go…. And then still the overhammer of my , I should fuel on 50 liter diesel approx. 2-3 liters of petrol! Was so stupid and did it, and only then read and made me smart! But still he drives… Do you think? Do you also have problems with such temperatures? Remember: My S40 was always in the carport with these problems and never had direct wind in there!
