• Ford Mondeo III (2000 - 2007) - 05 2.0 TDCi - Change it or keep it? - comments wel 14 Apr 2008 (Forum)
  Noticed advice on the perennial Mazda 6 diesel thread, to a guy who has bought a Mondeo - "get rid of it before the warranty expires", but remember earlier on the original Mazda 6 diesel engine failure thread 'Screwloose' saying that only a small percentage of TDCis give trouble but in his experience every Mazda6 diesel will come to grief given time.
• Forte diesel engine treatment 31 Mar 2007 (Forum)
  Having been given a jar of Forte's "Advanced" diesel treatment and quite willing to try it and see what happens I would still be interested to hear the views of anyone who has actually used it and come to a conclusion one way or another. I would much prefer to hear opinions from users (if any) rather than speculate on the psychological effects of the firm's advertising, or placebo effects, or the fact that it claims to be good so it can't be.
• 95 1.8 Diesel Fiesta bad starting 18 Mar 2005 (Forum)
  My 1995 MK3 diesel Fiesta has been a bad starter from cold, so I invested in 4 new NGK glowplugs a couple of weeks ago and it is still just as bad. It turns over fine and will go after about 15-20 secs emmitting a cloud of smoke when it fires up.
• Extended Services/Tuning Boxes 1 Jun 2004 (Forum)
  Is there any wonder that buyers of ex fleet and many privately owned turbo diesels run into turbo and fuel pump problems at less than 50k miles on the used car market, and then get an adverse opinion of the vehicle as a result of abuse by the previous owner/driver.??? After visiting BMW forums for some years, it is now common practice for most turbo diesels to run 17k to 20k before oil changes, which (Like H.J.)
• Developments 20 Mar 2017 (Forum)
    All are able to compete with petrol or diesel fuelled cars with respect to range.   The only new technology is in the fuel cell, all the other features are taken from battery electric or hybrid vehicles.    A local manufacturer has announced the production of an HGV tractor unit that can travel about 1,200 km between fill-ups.
• ford mondeo - Another dodgy mondeo tdci, wont start 24 Aug 2011 (Forum)
  I just took a 2003 Mondeo tdci, 130bhp model in p/ex. It came as a non runner (kind of) with 2 sets of injectors and 2 HP fuel pumps. the car would tow off and run fairly smooth at low revs, anything over 2500 rpm and it would cut out and need towing / bumping again. Immediate thoughts are fueling issues. I sent both pumps and all injectors to a well respected bosch and delphi diesel specialist.
• 2005 Mondeo TDCi (2.2) - Frozen Fuel Lines/Filter 23 Dec 2010 (Forum)
  Both last week and this week (temperature below -10oC) when trying to open her up (past about 2000 revs) coil light will come on, she'll splutter, cough and die a death, although if I'm lucky she will go into limp mode and I may just be able to get home. I'm convinced it's frozen fuel lines or the filter as the exact same thing happened the other week and when the thaw set in and temperatures rose above freezing she was ok.   Done the usual, that is keeping the fuel tank as full as possible, warming her up for at least 15-20 minutes first thing in the morning but this has not mad a difference.
• Ford Fusion (2002 - 2008) - 04 1.4tdci - unreliable starter..any ideas ? 30 Jan 2010 (Forum)
  the aec fail light has never cam on again but the car doesn't always start. Sometimes pumping the fuel pump gets it going. the pump is now never hard. the other thing is that when the car doesn't start i wiggled an electrical connection attached to the fuel lines, maybe the fuel cut off sensor, and the car burst into life. now every time the car refuses to start, a quick wiggle and it starts again or starts when it feels like it without me touching the wiring.
• Vauxhall opel combo 1.7 dti 2003 reg - None starter 25 Jun 2024 (Forum)
  Got a van I've had problems with. Changed fuel filter topped the the filter up with diesel, ran for a few weeks now won't start. Been told it doesn't have a lift pump only a high pressure pump in the engine. No faults have come up, tried using a hand primer pump on the pipe that goes into the filter with a blue tag believe that comes from the tank?

• insignia elite ecoflex 2.0 160bhp - Insignia knock 5 Sep 2016 (Forum)
  I have a 2012 insignia 2.0 diesel with 35k on clock and get knock/pinking/rattle sound when engine is cold and accelerating at around 2000rpm , as soon as temp gauge hits its normal position the knock/pinking/rattle goes, This only seems to show when weather gets colder as during summer its not there, no fault codes or warning lights have ever shown up,  The car is mostly used with shell diesel, engine oil and filter changed recently as it was happening before I changed it.
• Porsche Macan - not sure which to get 1 Jan 2015 (Forum)
  I think diesel is going to get taxed a lot in the future due to its excessive particulates. Have driven the diesel Macan which is v g. Did not like to see the extra pipe under  the fuel filter cap which has to be charged up every 12K miles and costing £125 each time though.

• Vauxhall Zafira Tourer - DPF on Zafira tourer and S-Max 17 Feb 2014 (Forum)
  Hi all, I currently have a 2007 Mazda 5 2.0 diesel which I am planning on replacing with either a Zafira tourer or Ford S-Max. One thing I have never liked about my Mazda is the fact that it dumps un-burnt fuel from failed DPF regens into the oil sump.

• Now what? 20 Sep 2011 (Forum)
  I've had it 10 years. I'm now doing 60 miles a day mainly on A roads it's showing its age and the fuel costs are biting. I'd made up my mind to spend somewhere around 7 or 8K and get a 2 yr old used fiesta or focus diesel (possibly an econetic) as seeing as how I intend to keep the car 8-10 years I assumed the better economy and lower tax would be beneficial in the long run.
• Ford Focus c-max - focus c-max buying advice 25 Sep 2010 (Forum)
  Your buying advice is very welcome. I've only done about 6000 mile/year over the last 3 years, so am unlikely to get a diesel unless persuaded otherwise. But I'd be interested to hear diesel feedback.  What is your experience of the petrol -- particularly of fuel economy on the 1.6 and 1.8? And any thoughts on the trim level?
