You'll need new actuator or find specialised store where they can rebuild such parts cos they exist... no DIY rebuild kit available

Next time when the fob refuses to work unlock then lock with key without opening the door and try the fob then, if no joy and you have to insert EKA again start with replacing the RF receiver and if the symptom still persists you'll have to change the BCU... btw do you have two fobs and does the...

Do you mean after you insert the EKA code the fob starts working then stops after a while or how? describe exactly what's going on

do you know to read electrical wiring diagrams? if yes see the attached diagram and you should see what to do, from F26 the feed goes to the aux relay... if not check if you have voltage on the light green/white wire(C0028 pin 3, attached), if yes and no voltage on F26 the problem is within...

It could if you dont have power on F26 cos there it goes the ignition aux feed

The gist is that "crossed B" on the odometer which was discussed to death on this forum depends on your luck to be the IDM or BCU: https://www.landyzone.co.uk/land-rover/discovery-2-b-symbol-near-odometer.367691/post-5080292

The WG wire has nothing to do with the red light, the warning light works with the NY wire the way you explained just that it has power through the IP from F27. The WG wire is from F24 as i explained before, the so called "exciter wire".

The big square FW5 is the "relay"(wiper control unit) and everything within the square(FW6 to 14) are integrated parts of it, it looks like a relay just a bit bigger, google out LR057366 to see how it looks maybe you find it then cos i dont know where it is on the early D1s like your's

NO, WG is ignition 2 live coming from fuse F24, it has power even without engine running

The power to the coil comes from F26 interior fusebox so troubleshooting is needed cos with this symptom the interior fusebox can be suspect as well

I dont really understand what you mean... the aux relay gets power on one contact terminal from FL7 then when it closes the power is sent to the related auxiliary circuits, i cropped the relevant part of the diagram, if you can't work with that better find somebody who is skilled with electrics

But can you confirm that no fault codes were logged? In such intermittent behaviours the engine harness is a quite common issue for Td5s regardless if its D2 of Defender, i've seen this kind of fault not once but there were injector related fault codes present every time, see this...

Depends how much you know about the D2's electrics but based on how you approached this issue i have the feeling that it's above your skills, no offence ... you can piggiback F7 for troubeshooting purpuse but this kind of bodge doesnt solve the problem

If no power on FL7 but the vehicle is running you should replace that fusebox cos it's very suspect unless maxi FL1 is not shot or has bad contact but then many important things would not work on that vehicle

You should have said the complete story from the beginning, the wipers are also through the aux relay and the relay gets feed from fusible link FL7 so check these

R7 but this one feeds many circuits not just the radio... why? you dont have power on F16?

Fuse F16 interior fusebox getting feed from the aux circuits relay

Maybe if you say what modell and year of Disco you have

OK... it was a misunderstanding in terms then cos you said "socket" first and for me socket doesnt mean connector or multiplug when referring to circuits

Maybe if the PO modified it to be permannent, there is no permannent live socket in the D2 from factory, all are through the aux circuits relay... al least on mine
