    Looking for members help on my recently purchased 53 plate Disco 2, which is very different from the Series 1's that I had in Dubai. There are a couple of significant problems I have inherited with this Disco since I bought it a month ago.

    The first is on the Central Locking, with the following symptoms/characteristics.

    With Key:-

    From Unlocked:-
    Locking locks only the driver’s door and does not activate the alarm

    From Locked:-
    Unlocking releases only the driver’s door and does not disable the alarm

    With Remote:-

    From Unlocked:-
    Locking locks all doors and activates the alarm

    From Locked:-
    Unlocking does not release any of the doors, although a “click” can be heard. The alarm is disabled and the driver’s door can be opened with the key

    “Three Amigos”

    The car had been converted to all springs when I bought it. The guy advised that the “three amigos” lights had come on just that day he brought it for me to look at, and an ABS sensor was suspect. I have my doubts.

    I had it in the workshop for checking where they said they had checked and replaced a sensor, clearing the lights. About 10 minutes after I drove it away, they came back. Initially, when the car was stopped for a while and restarted, it would be clear, but within a few moments they would come back and remain. Now they are on permanently.

    Any pointers on any of the above would be greatly appreciated.

    For the central locking issue first of all you have to replace the driver's door lock actuator cos it has a microswitch within which controlls the other doors too... if after that the other doors will behave the same we'll speak again

    For the amigos you have to read the fault code otherrwise it's a guessing game... or if you want to go in blind make the "option B" SVS wiring mod cos it's the most common and at a point it becomes necessary anyway

    I am in Carluke, not that far from you and have Nanocom Evo. PM me if you want to arrange getting plugged into that for the 3 Amigo issue.

    Hi there. Thanks for this and will certainly look into that and feed back. One question on the door actuator. Is the micro switch accessible/replaceable instead of the complete actuator. The workshop that had it rebuilt the door lock barrel to get key working and wondering if they messed something up/missed something out.
    On the ABS, have another member who has offered to run the diagnostics for me and will be taking him up on that, but can you give some more detail on the "Option B" SVS wiring mod. Thanks.

    googe out " discovery 2 SVS wiring mod" or see this with the addendum that you better cut the wires to the original connector

    Hi again. One more question if I may on the door actuator. If the actuator micro switch is indeed faulty, when using the remote. would that also prevent it unlocking the driver's door, as no doors unlock with the remote? Also, I assume the click I hear when I try to unlock with the remote is the "superlock" being released, as once this click is heard, I can open all doors from inside.

    Thanks again.

    Yes it would... just buy a new actuator don't try to be cheapskate cos it' a 10+ years item... i think that a 60 quid part worths it's longevity.... or try to save money and end up immobilised on a 15+_ years old vehicle... i replaced all 5 actuators last year while being 19 years old albeit only 3 were misbehaveing but i hope they'll last untill i'll be to decrepit to drive my D2 when i'll be 80 years old :cool:

    Hi Sierra,
    The new actuator is already ordered and I am waiting for it to be delivered. Fingers crossed it works. On the "Three Amigo's" side, a local member kindly helped me out with diagnostics on his Nanocom, and it identified the only problem as the nearside front sensor which had reported an intermittent fault 16 times. We reset it but it came back 30 minutes later.
    I have ordered a new sensor to start with, and if that does not work I shall replace the hub.
    Thanks.

    IMO you should have ordered the hub from the beginning cos it comes with new sensor too... from my experience i'd say that in max 10% of cases it's a sensor issue, in most cases it's about play in the reluctor ring which affects the air gap hence erratic sensor readings and that can be cured only by a new hub... provided it's not some very cheap chinese sh*t which can be DOA, i'm a sustainer of genuine parts but a hub is way too expensive as geuine so even me i opted for quality aftermarket made by reputable builders, for example : https://www.ebay.com/itm/Wheel-Bear...60-TAD100020-Quality-Replacement/332310032539

    Hi Sierra,
    Finally got the replacement actuator for the Driver door, and it now locks/unlocks remotely, but the others still do not unlock, so the situation now is as follows:-

    Locking with remote - all doors lock
    Unlocking with remote - only driver door unlocks, however the superlock is released on all other doors enabling them to be opened from inside. The actuators can be heard on all other doors trying to activate, but doors are not unlocked.
    Driving - At preset speed, driver door locks and all other doors can be heard to lock
    On turning ignition off after driving, driver door unlocks and all other door actuators are heard trying to work.

    On the "Three Amigos", with Nanocom the error is identified as the OSF sensor. With the diagnostic computer at a local workshop, it is identified as the OSR sensor which contradicts the Nanocom. When ignition is turned off, and vehicle left for a period of time, on restarting the lights are clear but reappear after approximately 1 mile on each occasion.

    Depending on which tester is within reach clear the code, unplug the sensor which is in thecode then after the amigos come back read again, i've seen nanocom to mix up the codes so if withnanocom will give you two sensor faults with OSF unplugged you know the other tool is right if you see what i mean then get a hib for that side.

    About the central locking IMO all the other actuators are fubar as well... though you can try to remove the door cards and unplug actuators one by one while trying to lock/unlock and if 3 doors will work with one unplugged replace the one which was unplugged cos it might create a load on the circuit affecting all the others cos all the passenger doors + tail door are on the same circuit

    Genuine hubs are the best. Yes they are expensive but will outlast your Disco now.

    And isn't it a toss that you buy a Nanocom and it gives you wrong info? What a joke!
