• Leon FR tdi. No thanks 16 Mar 2005 (Forum)
  and I'm keen to see if diesels have moved on from the older vw unit. He also promised 'a great deal', although his definition may differ to mine. I've also got those naughty men with hammers in my head shouting "Depreciation...."
• Renault Clio 1.6 "HELP" 5 Jan 2005 (Forum)
  Drove it home today (longest run its had in months as the guy towed it to get the engine job done, and the MOT test centre was only 4miles down the road.) and the fuel light was on as i set off.... fuelled it up, And set off home. Drove 30miles - Not going over 60mph for the work on the engine - Parked it up and thought "great!" Went out about 2hrs later and now it sounds like a diesel!
• Home Brew Petrol Additive 8 Jan 2004 (Forum)
  I'm thinking of mixing 20 parts of paraffin to one part of thin oil with the idea that this mixture would condition the fuel system. I've heard of using ATF for this, and I've got some left over from an old auto car, but when it runs out I thought I might use pump diesel instead as this would make it even cheaper. Since mine is a 'cooking engine' based on 1980s technology, I might use a much larger quantity - say one pint of the mix to a tankful (15 gal).

• Ford Fiesta - Fiesta 2008 TDCi Powertrain malfunction dash light 12 Feb 2020 (Forum)
  Only running on 3 cylinders and misfiring. Had the fuel injector on cylinder 4 replaced, at a cost of just over £380.   Car still not fixed, but looking around at other garages and getting other opinions before going ahead with what this garage recommended - a fuel injector loom replacement.

• Vauxhall Omega-B (03) 2.2 DTi (Y22DTH) - Omega-B 2.2 DTi Limp Mode & P1220 Error Code 1 Apr 2014 (Forum)

Checked the fuel system for leaks.

• Diesel Car - £3-4k 17 Jan 2011 (Forum)
    The car, as far as I am concerned is absolutely useless in the snow - no doubt due to the 19" alloys with the ultra low profile 235mm tyres all the way around. The simple fact is that the performance of the car in the snow plus the cost in fuel is untenable.  Accordingly, I am looking to sell my car and spend between £3-4k on a diesel.  Before posting, I made sure that I read all of the previous posts on this subject but many of the views and opinions seem so conflicting.

• Ford Focus 1.8 TDCi - Running problems - white smoke and no power 23 Apr 2022 (Forum)
  I have recently bought a focus 1.8 TDCi on an '03 plate, the car would only only start with easy start and then run rough with a loss in power. I changed the fuel filter (was full of dirty fuel and bits but not metal particals), air filter (distorted beyond recognition) and the flexi pipe on the exhaust (it has a big hole in) and still nothing changed. I had times when it would run ok for a mile or so and then suddenly lose power an limp everywhere again.

  The sunday times review states http://www.driving.co.uk/car-reviews/peugeot-308-mk1-review-2007-2013/ The 308 has been recalled 17 times (at last count) since its launch in late 2007, for electrical glitches, numerous brake faults, fuel leaks, a potential loss of power steering and even a collapsing driver’s seat; most recent recalls have been for problems with steering, shock absorbers, faulty rear windscreen seals and fuel leaks which could lead to an engine fire.
• Citroen C4 Grand Picasso - Engine warning light 26 Jan 2019 (Forum)
  I have had the car for c1 year (2015 plate), it has covered 42k miles, is fully serviced and does short 20 min motorway runs and to local town every day averaging 50 mpg. The Citroen garage has replaced the fuel filter twice, the first time after the car completely dumped all the diesel over the road and wouldn’t restart on after stopping. It is currently in said garage where and apparently it showed up a fuel line code but then they couldn't find anything physically wrong.
