    Slow to start hot or cold

    To carry on incase it helps someone in the future : Following on from my thread about my Discovery 3 TDV6 taking longer to fire than it should I think I've found the cause. The fuel rail shows a pressure of 130 kpa (1.3 bar) engine off, my understanding is that this should be held by the fuel control valve on the high pressure pump at 100 bar. When cranking the pressure builds until at diagnostics showing about 9000 kpa it fires. This is below the injector trigger pressure but I think this is a delayed figure due to the diagnostics frame rate as once running it is about 22000 at idle. This seems to suggest that the fuel pressure control valve spring has weakened. Is this a replaceable part it is it a new high pressure fuel pump needed? If the latter I'll live with it taking a bit of time to fire I suspect.
  2. Firstly this is on a 2005 Discovery 3 2.7 TDV6 but I thought being a common rail diesel and so sharing characteristics with other models this forum makes more sense for gathering knowledge, mods please move if you wish. I've already posted this on Disco3 but haven't had much by way of replies so hopefully the collective knowledge of LR4x4 will come to the rescue. I've recently bought the Discovery and it's always slow to start, worse cold at about 3 seconds but still slow warm, probably a couple of seconds. The battery is a new Exide one, 900cca, and turns it over fast but the time to fire is exactly the same as the knackered one it replaced. I've read the injector balances and replaced one so all are well within tolerances now but this made no difference. I would have thought glow plugs but there is no smoke worth talking about when it fires and that wouldn't account for the slow hot starting. EGRs have been blanked but the ECU shows there being a fault on one but I don't really see how this could cause issues? Wondering if the fuel pressure regulator could fail to hold pressure in the rail (I believe it should hold 100 bar engine off) so the pressure has to build before the injectors fire? Low pressure pump gives 0.4 bar ignition on which is alright. Other than starting it runs really well and returned 31 mpg over 650 miles of very hilly A roads last week so doesn't seem to be much wrong in general. Thanks in advance!

    Terrain response complete shutdown

    Not directly helpful I'm afraid but I would have it plugged into a diagnostic computer. I've had similar random messages in my recently acquired Discovery 3 and the faults have all been due to one module losing contact with another so your suggestion of damp in a connector doesn't seem unreasonable. For what it's worth I've bought an iCarsoft LRII code reader, it doesn't have all the bells and whistles of the more upmarket ones but for £140ish it does enough to show where the problem is. Comes as a nasty shock when the car says something is wrong doesn't it?

    Opinions and experience of radiators

    I fitted a plastic and ali one in my other half's classic mini a few years ago, the plastic was fine. Unfortunately the aluminium wasn't as a stone put a hole in it. Personally I'd stick with something more robust.

    Disco 2 or Disco 3 ..... Discuss!

    This is a well timed topic for me as I'm heading back to the fold as a two year old forces sale of my Z4. Unusually the two year old is our new rescue dog but she need something I can load her in without escaping. Head says Freelander 2 but heart says D3! In favour of the 3 over the 4 pre March 2006 reduces the road tax by £200. I know this isn't a great deal compared to running costs of fuel and maintenance but it's a lot to throw at the exchequer. I was tempted by another D2 but frankly my last LR was a D2 and it tanks as my worst ever vehicle in terms of electrical issues.

    Shipping Large Items

    I've also used DX freight for large items so they may be worth a go. The best deal I've ever had was from a local haulage company who fitted an item that wasn't time urgent in an HGV for very little money.

    Shipping Large Items

    I've used a company in the past that was along the lines of 'same day delivery .com'. I believe it was always TNT that turned up so you may find them to be of use. I moved a Triumph Spitfire bonnet with them for a remarkably cheap price so well worth a bit of searching.

    OT. Diesel misfire on a light throttle

    Thanks for the input, I was amazed that the inlet was plastic with a turbo on the other end. It's a fair point as it would be no different to a pin hole in the hoses. I agree that they are great cars, I had a 5.3 X-JS and still have a low mileage XJ40. To be honest I only bought it as I needed something more efficient than the Defender and was surprised at how good it is. The Mondeo based comments are a bit unfair although it's not a patch on older jags for ride quality, uses half the fuel though! I have thought about using the XJ40 for work but I'm a Quantity Surveyor so spend my days on building sites and I don't think 80's steel and cement would mix! As it happens it's gone from pretty constant to not present for the last couple of days. This rather makes me think that it's an electrical fault like a corroded connection but I would have thought this would have shown up on diagnostics.

    OT. Diesel misfire on a light throttle

    Thanks for your input. Luckily the egr on the x-type is at the front so wasn't too bad a job. I cleaned out the pipes and the manifold at the same time although they were all reasonably clean. The throttle body is a good shout, I'll give it a go, thank you. I'll update as to the effect. Agreed it's a great engine despite the current issue. Cheers, Barney
  10. Evening all, Off topic as its the 2.0 Duratorq diesel in my x-type but since the same (ish) engine is in the Freelander 2 I'm hoping I'll be forgiven and someone will be able to shed some light. On a very light throttle at about 1750-2000 rpm the engine feels like it is missing, its very violent, to the point that I either let off the throttle completely or accelerate; originally this only occurred at 50mph in fifth gear on a particular stretch of road which is very slightly down hill. However recently its become more common and I can induce it by using a light throttle in any gear. Originally I thought it might be the EGR as the engine was also smoking a bit so this was replaced with a genuine Ford EGR which got rid of the smoke but not the misfire (or whatever it is in a diesel). As a bit of background the car runs brilliantly, despite having covered 186k miles with no smoke when accelerating and pulls well with good fuel efficiency. I've checked all of the hoses and there is no sign of any splits, I've also plugged it into a code reader which showed no faults nor did the live data look odd, I had wondered if there was an issue with the throttle itself but this increased smoothly without any jolts etc. Any help would be gratefully received. Thanks in advance! Barney

    Land Rover series 3s (r6) 200tdi conversion

    I converted a series 3 to 200tdi sans turbo and frankly hated it. It was far (as in a galaxy etc) noisier and gutless although the mpg was better by a small margin. I say that as a firm believer that the 200tdi was the best LR engine by a country mile but it's better left as it's designers meant it to be.

    max towing wieght

    Bowie is quite right, absurdly, having passed my test in 2012 I would be better off using a medium sized car for towing than my D2 in order to maximise the weight I can tow. Madness. We're veering off topic!

    Shake, Rattle and Sound deadening

    I'm with Snagger on this, in addition to my D2 I have an XJ6 and it's silent to all intents inside. I admit the Jaguar straight 6 beats any other contemporary engine anyway but heavy, luxury, carpet knocks out everything else including tyre noise. My only consideration would be that carpet soaks up water and that's never a good idea. I did line my Series 200 di (carp, leave the turbo on!) With closed cell foam and 1/4" inch ply on top and it helps a lot although that was the entire vehicle so neither easy or cheap; certainly not as good as heavy carpet I'd imagine

    Wipac Crystals vs standard light units?

    I fitted Wipac Crystals to both an MG BGT and theyou were brilliant. I only kept it for a year but they weren't showing any signs of wear. I also fitted normal style bowls with halogen H4 bulbs to my other half's Mini and whilst not as good as the Wipac units they were still a world away from sealed beams. Personally I'd fit the Wipacs and consider it money well spent even if they need replacing every few years.

    xyz switch

    I would check the feed to the starter motor solenoid as well. Years ago I changed a gearbox on a Laguna and from there on in had symptoms like yours until I pushed the spade fully home again.
