  1. Hi.... Saw a 110 recovered to a local livery this week with no drive. They initially diagnosed a failed LT230 but I'm suspicious of the MT82 gearbox output drive shaft coupling....

    Lovely grinding noise when in gear and t/box in high or low range.

    I'm confident that the LT230 can take more of a hiding (Towing horses) than the coupling based on some searches.

     

    Does anyone have any more relevant experience I can lean on here?

    Vehicle has approx. 100k miles, clutch replacement in the last year or so I believe, generally well maintained from the appearance and quick look underneath.

     

    @ashtrans - Dave..... Should I be pointing them to you for an updated coupling?

     

    Regards

  2. Aaron,

    It does sound a bit like the MAF is gone on yours...

     

    Engine off, Unplug the MAF connector. Start the engine and let it tickover for at least 20 seconds. Then drive and see if it's different to how it was.

     

    If it's livelier from the off it could be the MAF. Easily tested if you know someone with any testing equipment or local garage to plug in and check for air flow...

    (Other than that, check for oil in the ECU plugs and clean out with brake cleaner if they are oily.... )

  3. A standard TD5 should manage a 1.2 ratio change well enough, but if you've gone for bigger diameter tyres, you may wish to look into tweaking the MAP. Don't try loading a Disco map onto a Defender ECU as this will cause all manner of issues.

    There are many good programmers out there that can help with a decent map, good power and torque increases, no excesses of smoke, and the really clever ones will also be able to write out the MAF, correct the temp gauge readings (They don't go into the red til 105C  as standard !!!) and correct the Cruise Control parameters to work with the new gearing ratios...

  4. When I converted mine to Auto, I called DVLA and didn't get any advice other than writing to them asking what I should do. 

     

    I wrote and followed up and was asked to call the DVLA to speak to someone. 

     

    I checked with my insurance and advised them of the change and no change of premium etc.

     

    Call them and see.

  5. Bit of an update, hopefully solved....

    At the weekend I changed the FPR, bleed valve etc in the fuel line at the oil filter block and replaced crank sensor again, although it didn't look too soiled this time.

    I then took it for a long drive to get it all warmed up and to a point where I could replicate the problem.

    After 35 miles I got a total cut, MIL light immediately on but dead engine.... Coasted to a hat, luckily in Lay-By.....

    Waited, started and it failed again soon after.

    I swapped in my spare ECU (Codes already learned for this purpose, so only a 2 minute job) and set off again. I did another 65 miles without issue.

    No fault codes registered in the original ECU.

    So at the moment it looks like the ECU has an issue that manifests when it's warmed up.

    I'll finish the pampering with a full oil change, greased props etc. and then the Oliver can take it for a nice long run before investing in a replacement / repaired ECU. (Hopefully)

  6. Well.. One of the pressure testing kits you found arrived yesterday @reb78.

    No opened to package yet but will offer feedback after the weekend.

    I'll test it out on the outgoing FPR and see what that's doing / not doing and fingers crossed I won't need to drop the tank and replace the noisy pump... Bloomin hate the standard tank guard on the Td5 90....

    It seems a weird problem. Usually injector seals or fuel pump are suspect IME with cutting out but you can make the situation occur for those and with the injector seals, purging will usually lead to a restart. This seems to occur more randomly.

    Can you check the fuel pressure? That might help rule out the pump.

    The seals and injector loom allegedly done recently and there is no issue with the running or starting.. No evidence of air in the system etc. Rocker cover has been off recently. Looks like a new gasket.

    Cannot check pressure without a way of measuring / adding something into the system. I don't own anything but willing to take donations :)

    The ECU / sensors don't record pressure. ECU only registers fuel temperature. All other parameters are air temp / pressure /water temp related.

  8. Hi all...

    I've had hands on this vehicle and still no definitive solution, so I'll share what I know and have observed in the hope this can be solved....

    Loom - All that's accessible from under the vehicle looks in very good order. No chaffing or breaks in the convoluted tubing that covers the loom. Checked from seat box, over rear of gearbox / Transfer box and along the side of the gearbox. (Still to lift cubby and check over gearbox)

    No oil at all in ECU Plugs.

    Fuel Pressure Regulator is leaking minimally but had covered the crank position sensor in diesel & oil.

    Fuel pump is quite loud.

    When driven, the engine just cuts on overrun. No coughing or hesitation, just dies. (So far, engine / fuel is hot / warm from a journey when this happens - Not replicated yet when cold)

    When you recycle the ignition the MIL light, oil pressure and battery symbols come on as normal, but no glow plug symbol. Engine will crank but not fire.

    Recycle again (Sometimes takes a minute) and the same, but with glow plug symbol, then it will run normally. 

    Done so far....

    Nanocom - no recorded faults.

    Normal readings when running.

    Throttle pots returning constant numbers through the range.

    Changed fuel filter and purged. Although noisy, purged well and started after two consecutive purges.

    Changed crank position senor changed.

     

    After doing this we could not replicate the fault.

    Oliver drove home and got most of the way and it happened again, but more often rendering the vehicle undriveable.

    Big Yellow Taxi and back to me.

     

    Yesterday it started fine and ran. No issues, but not able to replicate the long drive / warm the vehicle past a few miles.

    FPR, air bleed valve and return valve ordered and coming to be changed this weekend.

     

    I'm planning to get eyes on the rest of the loom and then aim to run it up to temp and try to replicate the problem. Assuming it isn't FPR and cuts out, and I can make it happen regularly, I'll pop in my spare ECU and see if it replicates again. (ECU ready and security learned, so quick swap and car will remain at working temp.)

    If not ECU, prime suspect then is going to be fuel pump. 

     

    Any suggestions why the ECU / system is not lighting the core plug lights when it won't start? Even when hot the TD5 shows this on the dash, but won't fire them etc.

    Anything obvious I should check?

  9. Although in a different league, we have a Leaf and it's a great commute vehicle... Quick, quiet but not so good for range. 100 miles real world if you take it easy ! 

    They will be very useable one day. Still can't see them taking over from IC and expect Hydrogen to be developed far more longer term....

    So, is there any way of making sure that the grease gets to all four parts of the UJ??????

    There was a post @Daan did a while back where he explained that he almost always greases his props off the car and had had virtually no UJ Failures in years. He uses a vice to pressure the cups that are greased to close up and force grease to the other cups.

  11. It's not a great deal of money, replace the MAP sensor.

    The ECU does have a fall back map for MAF failure and in some cases people do report an improvement, but in the majority of cases it will result in a lack lustre performance.

    Get a decent brand of MAF.. Siemens etc.

     

    I drove with a straight through centre section for a few years and have since reverted as it was a bit "boomy" and droned on long journeys.
