    Default TD5 hill start

    Hi all,

    Last night I became the proud owner of a 2002 TD5 Defender single cab

    It needs some work but nothing major. I took it to overland worx before the purchase and got a clean bill of health besides from a few leaks and worn shocks, brakes and other consumables.

    This morning however, I couldn't pull out of my complex I pull off just fine then as I go up the incline to get out the gate powerloss then stall. On the third attempt eventually got out almost didn't though. Pulling off at the next stop street felt like pulling off in third. Then it was fine afterwards although no more steep inclines.

    Am I looking at a worn clutch or just a cold engine that needs to warm up or am I a complete noob and don't know how to drive the old girl properly

    Td5s have a quite a fair amount of Turbo Lag to deal with.

    It boosts at 2000 RPM, so some revs before you pull away helps.

    Circumstances which make it worse:

    1. Altitude.
    2. Cold Engine.
    3. Hot day.
    4. Any number of faulty sensors which can be diagnosed real time on a good diagnostics.

    Walter at LRXtreme will be able to sort you out I'm sure. He's improved the lag on mine when others couldn't, normally by changing out a faulty sensor.

    The only way to eliminate the lag is a VNT turbo and some people do a map, I'm not a fan of going that route (map).

    Hi Sheldon,

    Congrats on the new defender, that is a beautiful design and you are in for many exciting evenings learning how it all works.

    For the problem described I would have a look at your fuel pressure as an incline inherently puts more strain on the fuel system of a diesel.

    If the car has sat for a while I would seriously consider doing an additive run to clean and lubricate everything.

    You can purchase a very simple and effective diesel injector tester from Adendorf too, you can then test the bleed back to identify leaks or inefficiencies.

    When diagnosing fuel system problems we always take vehicles over steep hills as it accentuates the problem.

    Could be turbo lag as suggested, changing the front silencer box to a free flow will help with spooling up of the turbo. And yes give her a bit more clutch play when pulling off on uphills. Power only starts coming in from about 1700 revs. Congrats and enjoy And cleaning the MAF will also help

    I took a Defender diesel for a test drive, but this involved a cold start and immediate steep uphill. Defender was dead as a doornail but i battled on over the hill. Then when engine warmed up, i tried another pullaway on that hill and all was fine.

    My diesel Prado did the same, it flatly refused to pull my Xplorer up a steep hill in a caravan park on a cold morning, with cold engine. I had to unhitch, drive through camp for engine to warm up and then leave.

    Methinks an auto gearbox compensates for this cold engine problem, whereas a manual gearbox cannot, unless you are prepared to bugger up clutch. Thus this problem only applies to manual box diesels, imho

    Blocked fuel return? Do you notice excessive exhaust smoke?

    And congrats on the Ďnewí Landy. Hang in there, itís worth it.

    Send a PM to Biltong, he's busy playing with TD5 ECU remapping for exactly the same reason.

    That is what low range is for - I used that often when having to navigate a steep hill first thing when cold with my tdi. A VNT trbo helped, but did not eliminate this.

    you can also put some 235/85r16 tyres on that will make the bakkie a bit less fatigued.

    SUCCESS!

    This morning I let it idle for a couple minutes. It wasn't much but the needle did at least lift a bit. I also made sure I had a bit more of a run up to get the revs in boost range and the Landy just purred out the complex no problem.

    I am looking at the removal of the centre silencer box as I've read a few good things about it, especially here. If the turbo can spool easier and quicker it will help with hill starts where I can't control the environment. End of the month it's going in for a full service and hopefully we can see if there is any sensors or issues that may be contributing to the problem.

    Thanks for everyones advice so far!

    Removing the center box is a huge benefit for a TD5, aslo remove the EGR and if you have some spare money, fit a madman or little blackbox to monitor EGTs. Mostly... go out and enjoy the landy!

    Yes- my TD5 was my first diesel (with turbo lag nogal) after years of a nice powerful 3.3l nissan petrol.

    Totally different drive. Taking off especially uphill have to get the revs up from the start. Revs are your friend.

    Yes I agree with several comments re cold engine. The TD5 doesn't like to negotiate steep slopes when its cold. I've used low ratio to get it up steep driveways before. Once its warm however, it'll tackle anything!

    There are isolated occassions when I have to give it a bit of foot on a cold engine, such as getting out of a quiet campsite at 5am, because Iím one of those guys who doesnít like to disturb others with excessive idling. The TDi 300 is not the quitest of engines. And Iíve never had turbo lag problems. This must be where the TDi 300 differs from the TD5.
