• Nissan Tino 2.2 DCI 2004 17 Aug 2006 (Forum)
  Then the fault reoccurs a day or so later . Back to the dealer who then tells me, that from the diagnostics it is a fuel pump problem and warns me that it may befuel contamination and if so, it is not covered by the warranty. Somewhat shocked I ask at what cost . The reply was "not too bad, only about £800" I ask him if he is living in the real world!!
• ? change diesel injectors (Fiat) 4 Oct 2005 (Forum)
  This is a 2.4 litre turbo charged diesel (not common rail) that has done 82,500 miles. My initial reaction has been to add some injection cleaner to a new tank of fuel. For the past few days it has been running fine, but this morning the problem returned. I believe it may not be firing on one or more of the 5 cylinders for a brief time due to fuel starvation.
• Car immobiliser problem - Honda Prelude 7 Sep 2005 (Forum)
  Between the wires, there was a "Ford" relay-type thing - It was a small yellow cube connected between the wires of this immobiliser. Taking this all out, the vehicle still refuses to start most of the time. The Prelude is a fuel-injection version (It's a 2.0L fuel injection petrol manual "K" reg) - I'm starting to get the sudden feeling there's a third box somewhere or in some form other than a box, but I've spent three days looking for it, and haven't found it, so dunno.

• Bad diesel???? 24 Aug 2005 (Forum)
  Unusual because it was always willing to pull well when running at 80 mph earlier in the day. Questions are: Does the premium fuel have anything that could cause this? (unlikely). Is it likely that normally nobody else will pay such an extortionate price in France for diesel and this fuel has been sitting in storage for months?
• Focus TDCi injector fault / power loss 29 Apr 2005 (Forum)
  It's OK for say the first couple of bends on a nice B road, or an overtaking squirt on the motorway from 70mph, but after the 2 or so corners / straights or if I'm going at 80 and want to accelerate - nothing there. I thought it was the fabled dodgy fuel pump, but the only fault code we could foind was P1200 - 'faulty injector'. The technician said that he has seen a lot of TDCi's with knackered injectors (they seem particularly prone to damage)which feed back data to the ECU, which shuts down the fuel delivery, presumably to prevent further damage. it's not a critical fault, so the glow plug light does not flash.
• 1.4 206 HDi mpg and low revs 1 Apr 2005 (Forum)
  I would have expected to be in fourth at 30mph and 5th at 40mph. Obviously having to be in the highers gears doesn't help my fuel consumption problem! I would appreciate any thoughts/advice Many thanks Jon
• Peugeot 306dt low compression 23 Jan 2005 (Forum)
  I have a '95 Peugeot 306 dt which has suffered from poor starting for a long time.The car starts, but runs very rough for around 30s from cold.When warm the car drives ok. After trying and failing to find air leaks in the fuel system,I booked it in with a diesel specialist who has said the fuel system is fine but has diagnosed low compression (270psi) on one of the cylinders. I have had three quotes from engine specialists to put this right,all around £1000.All of them seemed surprised that the engine should have this fault at a relatively low mileage (88K),but seemed convinced that it was pistons or piston rings.Two of the places said I'd be better off with a recon engine,or getting rid of the car before it got any worse!
• Vectra DTi Starting .. the last straw 23 Mar 2004 (Forum)
  I have a 'W' reg Vectra 2.0 DTi which has had the common problem of not starting if left for a while. Accepted wisdom on this problem is that it is caused by air leaks in the fuel system. This is generally cured by replacing the bleed off pipes, changing the injector seals, replacing the filter housing and fitting a non-return valve in the fuel pipe. So we tried all that. No joy.
• Saab 9000 Auto.. Buying advice ??? 27 Jun 2003 (Forum)
  Must be auto, good legroom as I am very tall, hatchback or estate and decent spec. And reliable and not horrific fuel consumption (ie. not V6 or V8s)!!!!! Many Thanks !!
• 306 XSi Engine behaving oddly... 11 Jan 2003 (Forum)
  Fuel problem? ignition problem? or something more fundamental like a head gasket? any ideas please?
• 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 Vivaro 2006 1.9 CDTI - Starting & cutting out problems 27 Oct 2018 (Forum)
  Got more difficult and more frequent. Good dose of Easy Start effective, long Jump start usually worked. Replaced Fuel Rail Pressure Relief Valve. Solved. With hindsight from purchase the van had low revs flat spot. Got worse with low power right up to 3000 revs or more.  Cleaned EGR ,not really bad, no change.Replaced MAF Sensor, problem solved.

• Nissan Qashqai? - Affordable new/used family car for long commute 3 Jan 2016 (Forum)
  The most important criteria are: • A decent sized boot for my greyhound (when I'm not driving to work) • Really good fuel economy - I'm looking for at least 50mpg. • Total monthly running cost no higher than my rail season ticket of £400pm (I may get a small compensation allowance on top but probably no more than £100pm).
• Vauxhall Omega-B (03) 2.2 DTi (Y22DTH) - Omega-B 2.2 DTi Limp Mode & P1220 Error Code 1 Apr 2014 (Forum)
  My "My Code Reader" shows one error code: P1220 - (A) Critical System Malfunction 1 (refer to checking procedure: trouble code description) - present. I've done the following: Changed the fuel filter, filled the new one with 'Diesel Magic' and run the engine for 15 min's afterwards. Cracked off the injector pipes and all are getting good pressure. Checked the fuel system for leaks.
• audi a4 v6 - 2.5tdi v6 start issue after camshaft replacement 19 Oct 2013 (Forum)
  during the 6/7 turns cranks does not seem to get any slower so seemingly battery is not the issue. doesnt make any difference if fuel tank is low or full have replaced temp sensor but no difference. if i remove sensor car always starts in 2 turns then fan comes on.im sure it would be more difficult in winter without this though!
• Throttle Hesitation in Xsara HDi 22 Mar 2013 (Forum)
  s like as if the engine electronics is failing to recognise a change of load and is very slow to change from a lean mixture to a richer mixture. Once the engine gets fuel, then it?s away as normal. My understanding is that Hdi engines have an ?overrun? valve that reduces the fuel to the engine when the engine load is low. Am I right? When the problem happens, the engine management light on the dashboard remains off.

• Is Diesel a false economy? 3 Jun 2011 (Forum)
  Ive been wondering this for a while, with fuel prices rising more and more people switching to Diesel cars, indeed for the first time new car sales has had Diesels in the majority in the UK, but is it a false economy? In almost every case brand new the diesel variant of a car will cost more than its petrol equivalent, even with better fuel economy and lower VED it can take 1-3 years (even on medium-high mileage) to break even and then begin to see profit.
