• Mazda 6 2006 - No power/turbo 15 May 2015 (Forum)
  I have changed oil and filter as it was due and thought this could of affected it, fault still there. Done a DPF forced regen and reset. Still no power. After doing the oil change I was sure the turbo kicked in for a very short period and I have just taken the car out again and no turbo. With foot flat to the floor just a slow gradual increase in speed as though is wasn't a turbo car.
• Will I get away with a diesel? 13 Dec 2014 (Forum)

• Volvo V50 2.0 Diesel - Volvo V50 2.0 Diesel Model year October 2009 22 Sep 2014 (Forum)
   I was thinking maybe the fuel filter requires draining but it has taken 4 months for the fault to reappear so this would seem unlikely. I have read reports of DPF sensor but the engine is not fitted with a particulate filter. Other comments have been the ERG valve whatever that is.   Many thanks for attention Robin Grimmett              
• Vauxhall Vectra V6 Diesel 2007 - Engine struggles on acceleration 3 Jun 2014 (Forum)
  As this is an Isuzu 3ltr engine inspection at Vauxhall concluded it is not an engine they are familiar with and responded that it "could" be the DPF. Mileage is 57,000. The engine managment light comes on almost immediately after 2nd gear. It struggles going up a hill big time. A little bit of history....The oil light came on a few months ago and it resulted in a new oil switch, which was duly repaired.

• Ford Mondeo - Mondeo/Vectra 2005 - petrol or diesel? 24 Jan 2014 (Forum)
  in the age range we are looking at (about 2005 reg) the diesel cars are the same price or cheaper to buy, which means that with lower fuel consumption a diesel may be a good idea. We know that for low mileage we don't want a car with a DPF, but everything seems to be turbo diesel.Does that matter? Anything particular to look out for? thanks!

• Golf Mk 7 Diesel - Golf Mk 7 mpg levels 18 Apr 2013 (Forum)
  The real world number will be under 45 mpg. This is much worse than my 170 bhp Mk 5. (After VW sorted the dpf and injector problems.) Do not buy this car for its mpg!!!
• Peugeot 307 - aftermarket particulate filter additive 13 Oct 2012 (Forum)
  I was looking on the net at  JLM PAT fluid DPF Cleaner. It says it replaces  EOLYS 176 and DPX 42. Haynes manual mention that EOLYS 176 and DPX42 are not mixeable or interchangeable so wondered if that EOLYS replacement can really replace both, hence asking if anyone has used it.
• All diesels - Which driving style produces the least diesel soot 24 Jan 2012 (Forum)
  Soot is a clear enemy of the modern diesel as it blocks EGR devices and DPF but how do you avoid making the soot in the first place? I have heard four theories: 1.Soot is mainly generated when a car is being driven hard which is why drivers accelerating hard from roundabouts get the characteristic black smoke but not at steady speed.
• Seat Leon 1.9TDI FR - Seat Leon 1.9TDI FR 17 Oct 2011 (Forum)
  My 'new' car is a Mk 1 (2004 model) Seat Leon 1.9 TDI FR 150hp, 1 owner, 52k miles and FSH. I decided to buy an older diesel to avoid problems with DPFs and the later piezo injectors fitted to VAG diesels.  The 1.9TDI also seems to be a fairly fuel-efficient diesel. Does anyone on here know what problems are likely with this engine/model, any preventative maintenance to prevent problems, etc as I'm conscious the car is 7 years old already and I've never bought a car this old before?
• Skoda Octavia - 1.9PD injectors 2 Aug 2011 (Forum)
  The answer was Siemens. So, the HJ car-by-car has it correct. (I also asked if it had a diesel particulate filter (DPF) and they said it didn't.) Having read a lot of bad things on the net about Siemens piezo injectors on VAG diesel engines, my impression is that the Siemens injector failures are way more common on the 2.0 engines (e.g. in the Passat) than on the 1.9 ones, the 1.9 seeming reasonably reliable.
• Ford Focus II (2004 - 2007) - Focus Car Manual / Maintenance Guide? 8 Sep 2009 (Forum)
  All, Following advice from HJ I purchased on Friday a 56/07 1.6 TDCi (non-DPF) from Car Giant. Having previously been a one owner company car I got the computer print out history from the leasing company but NO service book / manual etc. I am looking for the basic maintenance guides / service book etc that you would get on the purchase of a new car and wondered if these are available to download or purchase from Ford.

  What is the ideal diesel hybrid annual mileage? 30 Oct 2024 (Ask HJ)
  I know that if you drive less that 10000 miles a year, a diesel isn't the right choice. What about a diesel hybrid engine? Does that have a minimum recommendation?
