So. Left door done & it wasn`t too bad. Big shout out to Orangebean @ rangerovers.pub for the plastic tie tip however it was still a fiddle. Interestingly, either the chap at landrover putting the springs in the bags have either put the right door spring in the left kit bag & the left door spring in the right kit back or the part numbers are wrong for each door.
I didnt end up using MTC9290 - CLIP-RETAINER PIN or ALR68 Clip. Ive added more pics below as the ones on the definitive fix are missing
First job was to pop off what they call a cheater panel(just pulls off). This reveals Door card securing screw no.1. Disconnect the speaker connector. Remove the screw securing the remote handle escutcheon, remove escutcheon. Two more screws under the arm rest. Then its the door card pull and jiggle (might break some clips here x12). Disconnect Speaker connector. Carefully release the plastic sheet, I used a thin knife
Torch time. The Red Plastic retaining clip at the latch end just needs to be rotated anti clockwise then remove the control rod from the door handle.
Torx 25 bit for the handle inner securing screw, slide the handle forwards and rotate outwards to reveal the outer securing screw. Take plenty of pics of the inner workings of the handle to give yourself a fighting chance. Put the kettle on as here comes the fun bit. Remove old roll pin and seperate the old spring and plastic bit. Then its the plastic tie trick (Swearing optional). I found thicker ties held better but the bigger they are you lose space to move.
You can see where the mechanism rubs the spare bit of metal at the bottom of the handle, I just snapped mine off once it was back together again.
Now I`m waiting for the drivers door handle to arrive and I`ll follow up once I`ve done that side if there are any big differences. Hope this helps.
