• Skoda Octavia - diesel or petrol reliability 16 Nov 2012 (Forum)
  I am seeking some advice on whether its better to buy a petrol Octavia  over a diesel. My main worry with the diesel is the usual dpf, dmf and injector problems. I do about 40k a year and get paid 20p a mile fuel plus a monthly payment. I can't afford the new CR diesel and so it would be a PD if I bought one.

• BMW 530d E60 - Winter Operation 27 Mar 2006 (Forum)
  Noise appears to be coming from behind the dashboard/front of car. Noise eventually goes when the engine has warmed up. Any ideas what this can be? Viscosity of diesel at low temperatures or something else in the fuel system or controls? I use Shell, BP or Texaco diesel - no supermarket fuel.
• Volvo 440 diesel cuts out 11 Jan 2005 (Forum)
  My son's 440 diesel (1995) makes an awful screeching sound when it is started in the morning. It cut out completely yesterday, but re-started ok with some more diesel even though the gauge was well into the black. Is this noise the symptom of a duff fuel pump?

• Citroen ZX 1.9TD - need to prime fuel before starting 1 Nov 2010 (Forum)
  Had this problem a while. So far have changed all pipework in engine bay, leak off pipes, priming bulb and O rings on fuel filter housing. Even so, after about 4-5 hours standing it needs to be primed before it will start. When priming I can hear the fuel filter housing refilling with diesel. Can anyone give me any pointers on this one?
• Fuel filter change - 1.8D Fiesta 1996 2 Feb 2007 (Forum)
  How difficult is it to change the fuel filter on a 96 Endura engined 1.8 diesel Fiesta? I have done oil & filters on the car several times, next one due in a couple of weeks, and thought I'd stick a new fuel filter on at the same time. I don't have any hose clamps though - can I make do with pliers or a small pair of grips?

• Dodgy Esso diesel? 9 Jan 2012 (Forum)
  Anyone had what they might consider a slightly dodgy batch of Esso diesel recently? Filled up in Devon (almost empty tank) and fuel economy has dropped from 52mpg down to 39. Same journeys, same driving style, more or less the same conditions. {made non make/model specific}
