Hello and Happy’s New Year ahead. Got a problem with my Espace 3.0dCi, automatic, diesel, built in 2006: At acceleration, or at gradients the power drops. The speed drops, the car starts to jerk easily, then calms down again, sinks again, etc. When I try it with a kickdown it goes completely to the knees, but not out. When driving evenly, you megt that the car accelerates slightly at intervals and then slumps again. t no error message, also the workshop analysis has found no errors. The whole for the first time half a year ago > guess fuel supply > filter replaced > everything ok again. Then 3 weeks ago the same problem > after about a week without treatment everything normal again. And now again. error analysis again without finding. Last guess of the Renault workshop: Bad diesel fuel: Due to the ecological parts bacteria can exist, whose waste products filters, nozzles or sons twas clogged with deposits. This is especially the case with cheap fuel stations. Recommendation: use only Aral Diesel ultimate (the most expensive, mmh of all). I’m a little skeptical about this, it would have to go like this innumerable (i.e. millions) other cars, the min oil industry would have reacted to this in order not to lose market shares, or is there only the Espace particularly sensitive? Does anyone have an idea or corresponding information? Thank you
