Dear Volvo friends, I have often read helpful information here – thank you to all the good hints here – but now I have a problem that it is not possible to settle satisfactorily even after several workshop visits. Out of the blue the diesel went out during the last vacation, but then jumped again and also stuccoed more than 300km back home. At the external check of the machine still on site I have a diesel leak in the return line of the Einsp I had hoped that this was the cause. At the following workshop visit line renewed and everything went out first. Then he went out again after approx. 15KM spontaneously – error code said: fuel quantity faulty – next time: fuel quantity control faulty … diagnosis of the workshop: probably the pump is defective(?) – exchange may not be worthwhile – with the old car with 326TKm … Long research on the Internet has me suspect everything possible – but I should let Vo… read out the errors more precisely, then I would be smarter. Since the same thing: probably pump defective, 1500.- without installation, the next please … I drove completely down with it home and decided to continue researching and just continue driving to see how sluggish the pump can be: My results so far: it consumes 6.3 L as always, accelerates normally (up to 3000U/min – I have never kicked the old machine) and goes – > Before going out for the first time, I drove over a track with a washboard, then after five smooth kilometers it went out, so I first examined all the plugs, contacts or loose parts and found nothing. Where should I continue with the search, the ideas go out and I can’t believe that a defective pump is working so “normal” and then it is turned off. I hope that one of you also scho n experienced and can help me on the jumps – I don’t like to give a nice, though old Volvo little on the scrap – just because the rep is not worth it… Thank you in advance
