• Vauxhall Astra CDTi 2013 - Vauxhall Astra CDTi frequently running regen 23 Oct 2024 (Forum)
  crud in the DPF from when it was over injecting, and this also caused the regen to be interrupted on most occasions (pre the injectors being changed) so the DPF wasn't actually getting a good clean out. Does this sound right? Possibly it's actually okay and it's just residual soot / ash / diesel

  ?? " If not, the root cause is going to do the same again after I have paid a fortune to get the car working again. I have read on some of the forum about the DPF problem.

• BMW 320D Touring - Petrol vs diesel. Small estate 12 Jun 2016 (Forum)
  bet. KIA cee'd 1.6CRDI SW or Hyundai i30 1.6CRDI SW both delayed fitting DPFs until they absolutely had to. In the future, such cars may be banned from any city centres, but you wrote A road and country lane driving so that should not be a concern

  popping up every time I start it, I've since done about 800 miles and still there are no symptoms of any kind. The car still drives as if nothing is wrong. Any ideas? I would have thought the mileage is low enough for the DPF / Eolys to be ok unless the DPF can age without mileage
