Disco 2 Disco 2 V8 All doors but drivers locked but immobilizer working and car starting.

So you pull the handles inside on all doors and nothing happens after two consecutive remote unlock commands while you can open the driver's door only?
 
I press the remote, twice and the system works (like in you the receiver gets the signal and try to unlock) but none of the door locks open. I still need to use the actual key to get inside the car.
 
Then you have a serious problem as they are all superlocked which means something happned on that particular circuit... a nanocom or similar is needed to try to force the superlock motors unless it's a BCU or wiring issue... on a scale from 1 to 10 where are you when it's about understanding circuit diagrams and electrical troubleshooting? you must be above 8 to understand what to do based on my instructions or you need a skilled auto electrician who knows D2s
 
Damn, I am good with circuits, and following instructions can be done for sure. Would it be a good call to try to use a nanocom before going any deeper into the electricals?
 
The best would be to try with nanocom body outputs from BCU to force the superlock first to rule out the BCU before chasing other issues... you can try a trick but you'll have to do somehow to remove one door card from any door other than the driver's as to reach the actuator's connector, if you can do that i'll tell you what to do next

Actually it might work from the driver's door too if you are lucky but that's not 100% sure... so remove the driver's door card, unplug the actuator and splice with two wires into the pink/grey and pink/purple wires from pins 6 -7(attached) as to be able to feed those wires from outside, connect back the actuator and give earth and +12V to those wires for a second one way then unlock with remote, if nothing happens revert polarity and unlock again with remote... be aware, the extra wires must not be connected to anything while you unlock with the remote you must feed them for a second then let them in the air for remote command if you see what i mean ... do that and report the result, let the door card off for further tests if needed

Ok, i have a couple of doubts before i proceed. When u mean the extra wires cannot be connected to anything… should i pull all of them out of the actuator or need to cut them all and join after the procedure.
What would u use to give the 12v and esrth to the cables?

I dont understand your doubts, i can't explain better than i already did, i said "splice into" which means use posi-taps or skotchlocks or something into the wires as they are, it's nothing about pulling or cutting anything and you can take +12V from the fusebox and earth from any metalic part there.... if you have doubts after you read again carefully what i wrote and it's not clear means that my english is not good enough or you better not play with electrics
 
"be aware, the extra wires must not be connected to anything" This suggests me I should remove the extra wires from the connector but I guess is to make sure not to feed them voltage.
No your English is good, and I can fix stuff, just having doubts, thanks Ill do that and see what happens.

That sentence is valid completely: "...be aware, the extra wires must not be connected to anything while you unlock with the remote, you must feed them for a second then let them in the air for remote command ... which means to let them spliced into the circuit just make sure they dont get power or earth or short circuit on the free ends while you use the remote as the circuit at that moment to be like untouched... then you can use again those ends to reverse polarity for next test.... i really can't make it clearer sorry
 
I wasnt sure it would work but i thought worths a try. Then it's back to what i said in post #31 the trick with the wires must be applied to one of the other doors which are all on the same circuit
 
Will try the same process on the tail gate, which I think is the only one I can have access from the inside. What about a nanocom to disable it? would that be an option? I can rent one on ebay for a week pretty cheap
