• Merc vs BMW vs VAG reliability 19 Feb 2015 (Forum)
  Another car I would consider would be the Accord with the 2.2 IDTEC but have heard about some DPF issues with these, and the economy seems to be poor
• Fiesta 1.4 tdci- Revs fluctuating when cruise control on 18 Aug 2014 (Forum)
  I also noticed a pattern where it always occurs when going down an incline. When this happened before I thought it was the DPF regenerating. I am taking it back to the garage in 2 days time and I have made it clear that I refuse to pay the standard charge for another diagnostic when the last one did not solve the problem.
• VW Polo 1.6TDI 90BHP 2011 - Warning lights - loss of power 11 May 2014 (Forum)
  I've told her to use my car and we'll take hers to the VW dealer when I get home (I'm working away for the next 10 days) Could this be a problem with the DPF? or some other electronic glitch. Car has done 18000 miles. Any ideas? I'll also phone the dealer tomorrow but would be good to have some idea of the problem beforehand and how much it will cost to fix!
• Sprinter;Transit;Transporter - Which - Hi Top Van for local Deliveries 10 May 2014 (Forum)
  The new van needs to have a Hi top, wide access for loading ride on mowers via a portable ramp. The van will be used on these local runs so we have concerns about DPF 's blocking as the van will not benefit from a long run except on the odd occasion. Understand the Vauxhall/ Renaults have a poor reliability record and have no knowledge of the new Transits.
• Mazda 3 1.6 D Tamura 53 plate - fuel in Oil warning light ( MZ-CdD1.6 ) 3 Apr 2014 (Forum)
  The drive home is a bit more of a crawl, it was tonight but there is a 3 mile blast in the middle of it. Is this a DPF problem ie, should I take it for a 20 minute blast..or should I get it into the dealers ASAP tomorrow morning ?   Cheers
• Ford Mondeo 1.6 petrol vs Honda Civic 1.8 25 Feb 2014 (Forum)
  Hi Guys, I'm thinking of getting rid of my golf tdi for something petrol with less to go wrong. I.e no turbo, dmf and dpf. I've narrowed down my search to the 2 cars in the subject. Does anyone have any experience of these cars? Especially the mondeo, how do you find it with it having a 1.6 petrol engine, what's the mpg like and reliability?
• Volkswagen Golf V - Choice between Golf V or a A-Class 16 Feb 2014 (Forum)
   What I'm not sure about is does any of them have the following: DPF Dual mass flywheel Injector issues  They may also have one or both of the first two. but may not be problamatic....

• Ford Focus CC diesel - £942 for a service and work - pants pulled down? 7 Oct 2013 (Forum)
  Guy phones me after two hours and says (a) front and rear discs and pads need replacing (b) wipers need replacing (c) fuel additive needs replacing otherwise the DPF could fail and land me with a £1500 bill (d) brake fluid needs changing   Total bill came in at £942. Any opinions as to whether it's reasonable?
• Audi A4 diesel saloon - Low-mileage turbro failure 28 Aug 2013 (Forum)
  It then used a litre of oil in about 6 miles to the garage and subsequently the turbo, exhaust system and DPF had  all to be replaced, fortunately under warranty as estimated cost was £6,000. The car has engine auto-stop as a default and a journey to the office is 13 miles of motorway, the  off slip has lights and at red the engine usually stops when the car is stopped.
• Fiesta 70ps 1.4 Tdci - Chipping a diesel? 30 Jan 2013 (Forum)
  The car is out of warranty in November 2014 and I would like to keep it for a while. I have also taken into consideration the cost of changing a DPF. The car is 15 months old.   Thanks
• Budget Automatic Run Around - Help!! 15 Dec 2012 (Forum)
  Could get quite a bit of stop-start traffic on certain days hence the requirement for automatic. I will do the odd motorway run on weekends which should clear the DPF if that's a factor. - Budget 4-5K max  - Need something nippy and capable of not frustrating the heck out of my speed wise. - Size wize - prefer a hatchback but not averse to a saloon.
• Lexus Gs or Mercedes E class - Next car??? 17 Apr 2012 (Forum)
  Head says Give up car and use taxis when needed and/or hire car for any longer journeys Heart says Luxo barge at 2/3 year old to last next 5/7 years then will be 75 and driving will be hell by then.   Budget can be p to 20,00 Realise issues with diesel and DPF so wondering if Mercs are good/bad in this respect. Would not welcome £2000 bill after 2 years low mileage. Option is GS 300 with petrol Obviously MPG will be worse but on 4000 per year not really an issue.

  Buying a cheap to tax car for commuting 8 Feb 2012 (Ask HJ)
  I need a new car 1.3-1.6 for commuting 60 miles a day with good mileage and low road tax. Needs to be value for money?
• Watchdog 20/10/11 26 Oct 2011 (Forum)
  Anybody see Watchdog this week with the segment about the DPF's? If you didnt see it there was nothing that we hadnt heard before and was essentially the same thing we've been saying for ages to all buyers who come on here asking for advice. Its interesting how its taken the nations foremost staple of consumer advice programming so long to pick up on it.
• Vauxhall Astra Twintop 1.9 150 Design - Spanner warning Light 23 Sep 2011 (Forum)
  The peddle test revealed trouble code relating to the PDF P2452. I took the car out for a few long journeys to give the DPF chance to regenerate to no avail. Long story but I've been back and forth to Thorney Motorsport, they have carried out diagnostics, regenerated the PDF, changed a PDF sensor and updated the ECU.
• Peugeot 307 2.0 HDi 110 - Peugeot 307 2.0 HDi 110 down on power 18 Jun 2011 (Forum)
  So far I have replaced the MAF, MAP sensor on the intercooler, air filter, oil filter and oil and cleaned out the DPF. All of this has improved the performance but its still slow! I'm all out of ideas now, has anyone else got any suggestions? I have a Peugeot planet diagnostic and the engine is no longer reporting any faults, is there anything I can test using the diagnostic?
• Vauxhall Insignia - Faulty Flywheel on Insignia CDTI 160ps Ecoflex 30 Apr 2010 (Forum)
  I left it to a dealership to look at and they tried at first to tell me that it was an issue with the DPF, however, after driving it in traffic, they agreed that it was definately clutch related and stripped out the clutch and gearbox. I got a call earlier this week to tell me that the Dual Mass Flywheel was faulty and would need tobe replaced, however it seems that they are now on back oreder all across Europe.
• Skoda Octavia I (1998 - 2004) - 03 1.9 Tdi... solid? 28 May 2009 (Forum)
  He has found an 03 1.9 TDi from the same specialist garage (clearly an excellent place) that supplied the T, fsh and clean as a whistle but nearly 100,000 miles. Is the 1.9 Tdi unit decently solid or not? I doubt if the car has a DPF, but does it have one of these absurdly fragile dual mass flywheels, and is there any risk of the fuel pump going? It will spend quite a lot of time not being used, and most of the use it gets will be pootling.

  I have a 2011 Nissan X-Trail I have owned since new. It's approaching 130,000 miles and on long journeys I've noticed my MPG has dropped considerably....
