• Renault - 94 2.5 Master T35D Leaking Diesel 12 Jul 2009 (Forum)
  Hi there, I don't know if anyone can help me but I've a 1994 Renault Master T35D camper van with a non-turbo 2.5 diesel engine. Recently it's been getting air in the fuel system to the point that I can't start it from cold without first priming the fuel filter by pressing the plunger pump around 30 times. After that it starts ok. Last weekend while on a cycling trip I noticed fuel dripping out from under the engine.
• Peugeot 406 (1999 - 2004) - 01 2.0 Strange non starting fault 2 Jun 2009 (Forum)
  Did the same again and it started again. Got about 100yards and it stopped again. Decided to call AA. He checked tank fuel pump, was fine. Fuel getting up to filter no problem. Plugged computer in and it showed cam shaft intermittent fault. Changed cam shaft, started no problem. Left idling about 3 mins, cut out. Still struggles to start.
• Peugeot - Expert 2002 2.0 HDi - Failing power/boost/pick up 20 Jan 2009 (Forum)
  Symptoms: Struggles to get to 60 on a flat piece of road No pick up when foot pressed flat. Feels like boost from the turbo. No acceleration. Can barley get up hills. Eccesive fuel consumption. It doesn't get hot ever. Oil levels fine. No smoke No tapping No Knocks No warning lights apart from the usual Peugeot Airbag Light. The only bad thing I've done is running out of fuel which of coarse made the Engine management light come on, 10 months ago.
• Ford Focus (1998 - 2004) - 02 1.8TDCi car cutting out at speed 10 Dec 2008 (Forum)
  My reason for this lengthy post is that others may have similar problems so before spending loads of cash (which others have done only to find the problem persists)make sure you have a quality fuel filter fitted. I know nothing about filters (and I don't work for vw) but I think there is some additional item incorporated in the fuel filter for the focus but no doubt others more technically minded can enlarge on this subject.
• Volkswagen Passat (2001 - 2005) - 03 1.9TDi S 130 - intermittant non starting 17 Nov 2008 (Forum)
  Having called the AA out a couple of times when it broke down, on both times they thought it would be a fuel problem such as a fuel lifting pump or the like. The car has been to a vw dealer, they found nothing as its intermittant. It then went to a non dealer who replaced a fuel pump priming circuit, as this was one error code brought back from the AA.
• Peugeot 106 (1991 - 2002) - 1995 1.5 diesel - air in fuel system 15 Apr 2008 (Forum)
  I can push the pin into the plastic body against a spring pressure and by gripping the pin with a pair of pliers it can be completely withdrawn from the housing. The pin is about 1" long and 1/16 in diameter. When I operate the fuel priming pump diesel fuel is emitted from the join between the housing and the pin; so presumably air can also be drawn in here. What is this 'valve'? and can anyone venture an opinion as to what could have caused it to fail?
• Ford Mondeo III (2000 - 2007) - Oil leak on '05 TDCi (130) - fuel pump replaced 28 Jan 2008 (Forum)
  And I'm not aware of any other fuel pump on this engine. This, and everything else has been warranty work. So, has mentioning a slight oil leak won me a new common rail pump? I tend to think it has!

  Low Sulphur diesel is causing a higher incidence of fuel pump failure due to the decrease in lubricant. Discuss.
• You can't turn a pig's ear into a silk purse. 16 Jan 2010 (Forum)
  If you're a high mileage company car driver who'll get a car for 2 or 3 years, blast it up and down motorways and then throw them away, the only concern is diesel biased BIK and fuel costs (if you have to pay them.) again diesels win that argument. The bottom line is the compression ignition engine is a rough old dirty beast running on rough old dirty fuel, successive generations of diesel cars have ever increasing layers of complexity to try to make a silk purse out of a pig's ear:- Complex or active engine mounts, DFP filters, anti-pollutant additive systems, ever increasing fuel injection pressures, dual mass flywheels, the necessity for a turbocharger.
• PSA C5 Eolys additive for FAP filter 28 Feb 2006 (Forum)
  A detector in the additive reservoir with low fluid warning ? An injection system to load the main fuel tank ? A dedicated calculator to manage the additive process ? A fuel cap with microswitch,. When the cap is removed, the system detects the additive level before and after filling, and dispenses the proportional amount of Eolys additive into the fuel tank.
• R56 Mini Cooper S 2011 - Fault Code P0087 5 Aug 2024 (Forum)
  A friend's Mini is showing fault code P0087 - Fuel Rail/System Pressure Too Low. A garage diagnosed an issue with the fuel pump, sent it away for repair, and refitted. It has a slight misfire when started, but it quickly clears, however the MIL is on and the only fault code is P0087.
• Citroen dispatch 2007 1997cc 120 deisel - Lift pump relay image and location 13 Mar 2024 (Forum)
  Van cut out whilst driving.After rest started again,but not anymore .Can't hear pump when I listen at open deisel cap.Also disconnected feed pipe to fuel filter and turned ignition, no fuel coming through.

• Citroen Berlingo Multispace 1.6/115 2013 - Fault Code P000E 30 Oct 2020 (Forum)
  Car went to limp mode and will not rev over 3,000rpm.  Fault code per generic OBD II reader is P000E which apparently means Fuel Volume Regulator Control Exceeded Learning Limit The fault clears but re-appears 15/20 seconds after re start.  May be relevant that it first appeared half a mile or so after topping up fuel tank from approx. half to full.
