• Ford Focus III - Diesel Pariculate Filter Problems 4 May 2010 (Forum)
    I bought the car from a well know national car supermarket.  In January the engine management light came on and it turned out that the DPF needed repenishing.  As this was not covered in the entended warrenty I paid for, I had to bring it down to Ford and paid £100 for it.  Now the light has come back on and having taken it back to Ford they have said the DPF needs relacing completely and have quoted £850!!!!
• Mazda Mazda 6 (2008 -) - 08 2.0d Extreme Diesel Dilution - DPF 11 Nov 2009 (Forum)
  To cut a long story short the problem i had of the car over-accelerating on it's own was appartently due to a DPF problem which let diesel in the oil. I had my full oil test report back today, my self & the garage were stunned at the result. Analysis: Diesel Dilution testing Result: 62 Units: % I had to make sure with the testing company that they never made a mistake with the readings, they assured me that there is 62% diesel mixed with the engine oil.
• Car with Good MPG 17 Oct 2020 (Forum)
    I would ideally want MPG of around 50 plus.  I have been thinking of Fiesta 2009/10 1.6 tdci non DPF or a Megane 1.5 dci 2011(unsure about dpf).  For me after MPG, reliability and holding as much value is most important.  Advice would be great.  Thanks

• Peugeot 307 - Fault 9 Sep 2015 (Forum)
  My Peugeot as recently had a fault with the dpf and the mechanic cleared it out and as he did not have the software could not reset the onboard computer. After awhile white grey smoke started to come out of the exhaust and a burning smell. Took the car to a diagnostic garage and they ran tests and reset the dpf but noted that the glow plugs stay on and do not switch off.
• Range rover petrol or diesel? 26 Aug 2014 (Forum)
  However, I drive only about 5 miles a day and about 4000 miles a year in total. I have a xf at present which is struggling with dpf issues. Porsche dealer said that cayenne diesels do not have dpf issues. Is that right? I am keen on range rover though and not sure whether to go for diesel or petrol.
• any - acea grade c3 17 Sep 2011 (Forum)
  acea c3/c4 are stay in grade high performance fully synthetic oils for petrol and diesel engines with diesel particulate filters and Three way catalyst systems. These oils will extend the life of thw DPF and the Catalytic converter.   So is this why dealers are not putting in the correct grades, so that further down the line we will have no warranty claim if we don't notice the "wrong" type or gade of oil is in the engine, and then we have to pay for a very expensive DPF filter at our own expense.
• Honda CR-V - Correct Oil for Honda CR-V 2.2 CTDi 9 Sep 2011 (Forum)
  The amber oil level warning light has just come on my 2007 CR-V 2.2 CTDi (the first of the new shape April 2007) I have visited the Castrol website and apparently the oil I should use depends on whether the car is a DPF version or not. Is there anyway of knowing if my car was fitted with a DPF? Any thoughts on which oil I should use to top up greatly appreciated.
