  1. I would suggest that what you're seeing on the rev counter is the result of a (possible) problem rather than the cause, as with the crank sensor, if it works normally otherwise I'd say it's not at fault.

    Perhaps it's a switching glitch from the glow plug relay being activated?

    Has it only just started doing it?

    I added a rev counter to my Td5 90 (2004,) not a LR supplied one but from Smiths,  https://www.smiths-instruments.co.uk/landrover

    It looks very similar to the original VDO one and connects the same, when I turn on the ignition, the needle goes to full-scale then returns to zero, some kind of self check thing I assume, I wonder if yours is doing something similar?


  2. By a strange coincidence, I've just been looking at my crank sensor as mine is often slow to start, hot cold or otherwise, it will crank for some time before it fires but then runs perfectly fine, I am getting a "noisy crank signal" error on the Nanocom. Just for reference I checked the resistance between the signal wires at the ECU and found a resistance of 1.24KΩ which I would guess to be about right given the type of sensor.

    If the engine runs normally I wouldn't really expect the sensor to be failing, they usually either work properly or not at all, (about 1KΩ or open circuit,) and the engine won't run if it's failed.

    I find I can bump-start the engine if I'm parked on a slope and it starts immediately, so this suggests to me that the starter motor could be interfering with the signal, possibly due to sparking caused by worn brushes, or even a failing battery.  It's also worth checking the security of the earth connections, battery to chassis/engine and the second one from chassis to engine near the starter.


  3. Why not get one cylinder to TDC and poke a sick down the glow plug hole to gauge the depth and compare with the length of the new ones.

    Maybe it's had the wrong ones fitted previously?

  4. "defender td5 2011" ?  

    "Turn the key and it's dead" -

    Any clicking noises?

    Do the ignition lights dim when trying to operate the starter?

    Possibly flat battery due to faulty alternator or even just broken belt, also backed up by battery light coming on first.


  5. There is a pressure sensor on the AC system, so I'm guessing that it would inhibit the clutch in the event of low refrigerant pressure, specially since the gas also carries the lubricant for the AC compressor.  No gas = no oil = knackered pump.


  6. I use a Nanocom Evo for my Td5 90 and Disco 2 for the engine ECU, ABS and alarm, I'm not so sure what use it would be on a 300Tdi though, other than for the 10AS. 

    There might be a simpler/cheaper alternative for just the 10AS. I'm sure someone more knowledgeable will be along shortly.

  7. Depending on year and configuration, if yours is 2002 onwards and is equipped with ABS, there should be a yellow/pink wire from ECU pin 19 going to the ABS unit that you could tap into.


  8. The power to the ECU is linked to the inertia switch so as to kill the engine in the event of a crash, so yes it does need to be linked.


    I fitted a pair of horns that I took off a VW Golf scrapper, I had to make a bracket for them to fit in place of the original single horn but well worth it. I also added a relay to switch the power directly from the battery.

    Just be aware that if you're fitting salvaged or new conventional horns, the back, (mounting screw) of the horn vibrates so they need to be mounted on a flexible strip to work properly, if you mount them onto a rigid surface or bracket, they won't sound at all well.

  10. I wouldn't risk sunflower oil on my Stihl, I doubt that it's lubricating qualities are up to the job. If I had to use a substitute I had to hand temporarily, I'd use a heavy gear oil, EP90 for example.

    The proper stuff is sticky but also thixotropic, it sticks to the bar and chain without being thrown off by the centrifugal force

  11. The indicator relay is designed to flash quickly in response to insufficient current being drawn on the circuit, usually caused by a failed bulb, if you're sure the bulbs are all OK I'd check on the earth returns from the indicator lamps, particularly the rear ones, it could be they're getting a return via the tail lamp filaments which wouldn't allow enough current to operate the relay properly.

  12. I'm not 100% sure about the Puma models, but on the earlier Defenders that light is also linked to the handbrake switch, it's contact closes to ground when the lever is lifted, it could be that the switch it out of line or damaged or the wire is trapped somewhere and intermittently shorting.

  13. There's only a single supply fuse for the 10AS unit, (fuse 7 under the seat box,) so if the immobiliser is working that suggests it's ok.

    Immobiliser, interior light control and central locking are all functions provided by the 10AS but it needs to be programmed accordingly, (via the OBD port,) they can lose their configuration or get corrupted, mostly I think due to the battery being disconnected, you'll need to find someone locally with a Nanocom or similar to set it up.

    I don't believe the spare connector has any bearing on the issue.

  14. There should be no 12v feed to any of the lights with the switch in the off position, the ground sides of all the lights are permanently connected to chassis ground and rely on a positive feed from the switch to operate.

    Sounds to me like you may have a faulty dim/dip relay with an internal short circuit, I'd start by disconnecting the dim/dip resistor, on the later cars it's mounted inside the front RH wheel arch, I'm not so sure of the location on the earlier cars.

    I think most UK car owners have already disabled the dim/dip for reliability reasons as they're not a legal requirement over here, not sure how you stand with that Stateside.

  15. Looks to me like it could be simple aluminum corrosion, if it's come from a farm environment with acidic animal waste getting splashed about, that could do it.

    To be honest though if that is the case, I'd be more concerned about the condition of the chassis.

  16. If you're not too far from Halifax, it's worth giving Michael at Adamson Independent Automotive a call.

    He fitted my 2004 90 with a new Clutchfix heavy duty clutch, pressure plate and release bearing, (DMF and cylinder not required.)

    I had to leave it with him for a couple of days but ended up very pleased with a job well done for £385 all in.
