    Yes, you can't acees the matrix other way

    That's why i said to undo both pipes and join them together, not hard to do, all you need is a short piece of pipe to insert between them and use the existing clips

    The matrix has permannent coolant flow and the heating/cooling is managed by the servomotors which are opening/closing the flaps, when cooling is set the flaps for the heater core are supposed to be closed and all the air should go through the...

    We pre-fill some fuel filters with it neat, we've put 2-3 large bottles in with a quarter of a tank and I'm pretty sure it does very little at all but it's great that it's worked for you!

    the man mentioned it: I used it myself too once( THIS ) and felt some slight improvement but not more than with Liqui Moly or Wynn's.

    That's a classic sign of low gas level, get it regassed at a specialist

    Sierrafery is on the money, as long as your immobiliser works, it ain’t getting stolen without a stupid amount of research, work and testing. You can’t even talk to the BCU with the immobiliser enabled, it may be old but it works as it should and...

    Even the real owners have problems getting in and starting sometimes :p. I would say its pretty safe as standard. J
  • sierrafery
    Which is safer than any of the newer CAN-bus technilogy these days which are easyer to be acessed by ”specialists” with proper scanners who dont even know how these old security systems were conceived. There is almost zero possibility for an...

    Then read the code with nanocom or hawkeye(i dont know other tools to be 100% reliable with the Td5 engine management) but as long as the EML comes on it can be only the crank sensor or TPS unless the ECU is at fault.

    New used BCU arrived today from USA. Car is now up and running! Thank you sierrafery for helping! Best regards

    sierrafery replied to the thread Disco 2 Engine Power loss.
    Hi, those codes seem to come from some generic scantool, anyway if it's 10P engine and automatic box the main problem is with the crank sensor or it's wiring/plug hence the EML warning and CAN fault code and the MAF fault is irrelevant unless you...

    I've started to run through the diagnostic guide. Solenoid valves resistance, all close to spec: Front/Rear inlets 7.2Ω Front/Rear outlets 3.9Ω Wheel sensors resistance: Front left 987Ω Front right 988Ω Rear left 987Ω Rear right 988Ω (same...
  • sierrafery
    I dont know what's the real problem but as long as they react to the fob it's nothing electrical that's certain
  • sierrafery
    If you hear an activity in the latch while you give any command with the fob or dash switch the problem is definitely not electrical and you might have bought two "tired" actuators which gave up the gost at the same time, it can happen with used...

    sierrafery replied to the thread Disco 1 D1 ABS.
    yes seems so, quite strange... then measure resistances and compare cos even if the solenoid works it might have a resistance out of the diagnostic protocol's range, the whole diagnostic guide is attached
  • sierrafery
    sierrafery replied to the thread Disco 1 D1 ABS.
    Yes, then if no click double check by splicing into the next solenoid's wire to make sure the click is audible(i tried on D2 and i heard it) so if the RHF doesnt click and the other does you know but if no sound on any solenoids compare...

    sierrafery replied to the thread Disco 1 D1 ABS.
    Find the wire which ges to it from the modulator's connector and splice into it with +12V cos afaik the earth is common for all and if it clicks it should be OK, or find the wire for other solenoid, measure resistance and compare if you see what...

    Hi, you can download for free the whole electrical trubleshooting manual from the web just search "Discovery 1 ETM pdf" or see THIS , just read the introducting user guide to know how to corroborate the wire colours and connector views cos it's...

    sierrafery replied to the thread Starting issues.
    I'm not sure that the scanner you used is reliable but if it is i see that the fuel pump drive is off so you can't expect it to start that way, the pump should be on for about 3 minutes after the ignition was turned on then if the ECU doesnt get...
  • sierrafery
    sierrafery replied to the thread Starting issues.
    +1^^^ and a fuel pressure gauge connected to watch the pressure while cranking cos on defenders i've seen many cases when this kind of stubborn starting issue is fuel supply related hence no fault codes albeit a nanocom or haweye is compulsory...
  • sierrafery
    IMO that spike in the readings is the moment when the symptom occurs and it can be caused by a weak contact somewhere(ECU plugs or other connector, oil acts as isolator in the red plug) otherwise nothing wrong with the TPS or other sensor...

    sierrafery replied to the thread D2 aircon fan availability.
    Unfortunately that motor seems obsolete all over the place, i bought one as well about 2 years ago then sent the bad one to a rewinding service and they made it like new for half the price so i keep that for spare.
  • sierrafery
    What scantool gave you that code? remove the ACE relay, bridge the contact's cavities in the fusebox with a wire, read all te live inputs at idle and post them here then i'll tell you more ... also make an output/circuit test for the PCV and DCVs...

    I meant the SET+ input in special(with CC on of course), if you see that one on command and nothing happens the only suspect i see is the ECU
    • 1750342039826.png
  • sierrafery
    I don't think that the TB ratio can affect that but if it was remapped that might have mixed up things coz as long as you see the inputs the problem is definitely with the ECU... if you go into the Info section what you see at Cruise control...
