• Audi A6 2.7 tdi - Warranty - Petrol Contamination 24 Sep 2011 (Forum)
  At this point the car was taken to an Audi dealers who diagnosed petrol contamination in the diesel (requiring a filter and fuel change and fuel tank clean but...."This isn't under warranty as it's not a failure of the car! " It was interesting that when I tried the car out, it was extremely low on fuel and the salesman put a very small amount in whilst on the test.
• Honda Accord Tourer (2003 - 2008) - 2005 2.2 Fuel Problems 5 Feb 2009 (Forum)
  Took it back to the garage, same problem low fuel pressure, so they looked in the fuel tank, apparantly it was full of black sludge, by full I think they meant there was a considerable amount at the bottom, that was being drawn into the fuel filter.
• Escort Van 1.8 Diesel (non turbo) - Escort Van 1.8Diesel Cold Stat Problem 10 Oct 2011 (Forum)
  I have noticed that one of the diesel injectors has a leak, could that cause the fuel to creep back??? It seems that i am running out of "cheap" options. The pump timing has been checked, could it be the pump itself? but it does run ok once started, abeit a bit smokey these days and not very quick (bluey/whitey smoke...related?)

• Fuel prices California style 11 May 2008 (Forum)
  The folks out here are starting to hurt with the fuel prices. Here in Placerville the cheapest regular unleaded is now $3.98, with premium at $4.45...diesel is also $4.45 US gallon. There was a front page article in USA Today yesterday about how the latest increase is having a major impact on how people are changing their driving habits...big trucks sales are taking a hammering, and even my friend with her 2.5 Outback now remarks on how expensive it is to gas up.
• Supermarket Fuel 30 Nov 2007 (Forum)
  There are 3 diesels in the family - and all of us have nnoticed that when we use supermarket fuel (especially Tesco) we get 3 to 5 mpg LESS than we do when we fill up with Shell. Fortunately, our Shell garage sells at the same price (sometimes cheaper - even with Tesco 5p off a litre) than the local Tesco and Morrisons, but I've tended to use Tesco simply to get Clubcard points.
• Customs casts net wider for fuel smuggle 8 Sep 2005 (Forum)
  Interesting article on how Customs are tackling fuel smugglers who are removing the red dye from diesel. (Today's Daily Telegraph). http://www.telegraph.co.uk/money/main.jhtml?xml=/money/2005/09/08/cnfuel8.xml Sounds as if you could do far more harm to your engine than the money that might be saved. -- Roger I read frequently, but only post when I have something useful to add to the thread.

• Mazda Mazda 6 (2002 - 2007) - 04 2.0 Smoke on start up 22 Aug 2015 (Forum)
  I have seen this fault mentioned on forums before, but there has been no suggestion as to the cause. Being reasonably familiar with diesel engines this is the sort of smoke you get when there is excess fuel at start up i.e. it is effectively unburnt fuel, and this would be consistent with its smell. The car always starts very quickly so it is not due to diesel building up due to long cranking before starting.
• Ford S-MAX - White smoke from under bonnet. Losing the will! Please help :-) 25 Feb 2023 (Forum)
  It was a perished O ring on the fuel line. Driven car again and white smoke still coming out from under the bonnet. My question is... could this simply be the diesel that had leaked burning off or should I take it somewhere else for investigation?

• Honda CR-V III (2007 - ) - Who sells the most economical diesel for my car? 18 Apr 2008 (Forum)
  Is this because I am now through the 1500 miles mark, because I am using Shell rather than Morrisons or Tescos(amongst others) or is there another reason. If it is the Shell fuel, is there any other make that will give me even better fuel mileage?
• Ford Escort (1993 - 2000) - 93 diesel starting problems. 4 Dec 2007 (Forum)
  It would not restart so i tryed to bump it it started but immediately died and still wont restart. It turns over fine but just wont get going. I changed the fuel filter and plenty of fuel came out, but now it doesn't seem to be getting fuel thru it when i press the self prime button. It did do this once before in the same spot lol but managed to get it started about an hour later after just leaving it it did take awhile of cranking tho but started and ran fine since.
• Rover 420 SDI 2 litre turbo diesel fault 31 Jul 2007 (Forum)
  Interestingly, if the engine is turned off for a short period (say 5 mins) after even just a mile or two from cold, it runs perfectly when re-started. The coolant temperature sensor, fuel filter and the glow plugs have been renewed. I only use Shell diesel fuel, never supermarket products. Any ideas? Thank you,
• Air leak in fuel system [Diesel] 3 Mar 2003 (Forum)
  Xantia 1.9 TD 1995 92000m NB. Same Xantia as in Smokey start thread. I'm pretty sure I've got a leak somewhere in the fuel lines, when the engine is cold is runs rough for 5-10 seconds before smoothing out. After that its fine. Filters, oil etc & glow plugs are fine (brand new Beru), theres no major smoking though if you rev it while its having its coughing fit it will puff white smoke but not a great deal.

• Astra diesel cold starting 3 Dec 2002 (Forum)
  Once warmed up slightly -no problem. The glow plugs are new so there should be sufficient heat. I have a new air and fuel filter to fit in case there is a blockage in the airflow or moisture in the fuel but would appreciate any advice as to other potential solutions Allan

• Non-ECU Diesels 5 Oct 2001 (Forum)
  Cavalier Replacement? thread, David Woollard made the point: ?It is still a point everyone has to learn that ECU fuel injection in old cheap cars is going to be a major problem in years to come, often they aren't worth fixing.? He went on to suggest a (non-ECU) Xantia diesel. This is a point that is regularly made, for the benefit of those of us that don?
• Fuel (What do you do?) 28 Mar 2008 (Forum)
