  What are the manufacturers doing to improve DPF technology? 21 Apr 2012 (Ask HJ)

• DPF-Short trips-alternative solutions 14 Aug 2008 (Forum)
  As Screwloose outlined yesterday. DPF and short trips don`t go well together. What`s the answer for those of us still running diesels without DPF? Hold on to the current car? even taking an approach that would see a major expense such as a new engine- or other several thousand pound repair- preferable to a new car with DPF?

• Renault Clio - dpf cleaning on a renault clio regeneration 7 Sep 2021 (Forum)
  We Have a 2017 Renault Clio 1.5 diesel with 26,000 miles on the clock which we bought new. The car isn't giving us any issues but I do read about the dpf and the damage that short journeys can do to the dpf. What is the best way to give the filter a good clean out?  I have read that the Clio has a regeneration system that will clean out the filter on a long run, but unsure how this works.
• Hyundai Tucson Diesel 2019 Plate. - DPF ISSUE 12 Aug 2025 (Forum)
  Hi All I bought my 2019 Tuscon when it was 6 months old, despite doing on average 10 miles a day during the week and longer runs at the weekend and on holidays etc, it had zero issues, I broke my ankle last September, the Car  was stationary for 2 months and has been a nightmare since, essentially around 15-20 miles the dpf light comes on, and then the Engine warning light, a few months ago the Engine light went out and obviously the dpf light goes out/resets when the car is turned off, i use nothing but Esso premium fuel and have tried a lot of different dpf cleaners, a friend who's a mechanic has looked at the car and he cannot see why there's a problem, and that the dpf maybe faulty, I suspect that the 2 months the car was sat still caused a soot build up, can anyone recommend a solution please.
• VAG 1.9 TDI - Procedure for re-connecting DPF back to turbo? 14 Jul 2020 (Forum)
  It seems like the V band clamp is almost too small to clamp onto the turbo AND the lip of the DPF, however this is the one that was removed....Should I be using a new V band clamp?  Does the dpf connect 'into' the turbo itself or does it simply line up with the face of it? If anyone has a link to any clear images it would be greatly appreciated!

• Ford S Max 07 2.00 Titanium - dpf limp mode 12 Nov 2014 (Forum)
  Limp mode happens rarely but car can be driven again after 15 minutes. Will a hard drive (how hard?) regenerate the dpf. problem - hardly any dual carriageway in my part of Norfolk. Can I use A roads in a lower gear?  
• Nissan Note DPF 25 Oct 2010 (Forum)
  The new 1.5 Diesel Nissan Note from November is Euro 5, 110g/km and has a DPF.Can anyone advise if the current model, Euro 4, 115g/km has one? I realise all Diesels will have DPFs fitted before long, does that mean that they will all be unsuitable for town driving due to regeneration issues? Many thanks

  For the DPF I've seen other places advertising a similar service "from £99"  but whether this is actually true or not I don't know. Does anyone know what it would normally cost and is £300-400 excessive?
• EGR / DPF failure rate 6 Mar 2017 (Forum)
  I understand people are having issues with the EGR/DPFs etc, but without knowing the failure / issue rate I don't know if it's similar to being struck by lightening at one end of the spectrum, or getting grey hair at the other.

• Citroen DS4 2.0HDi 165 - elm327/Torque app for DPF data? 2 Sep 2016 (Forum)
  Has anyone used a OBD2 ELM327 coupled with Torque Pro app and managed to access DPF data such as pressure (that one at least) or even saturation %, last regen... Or maybe I cannot see the sensors available to view on the Torque app because citroen ECU management is not allowing it?
