I think the wiring has finally given out in the hinge/bellows section on driver's door. It's had various fault codes and lost speakers a while ago but now having locking issues.

Looking around online it's seems pointless to try to patch the 17year old wires and replacing the loom seems the only realistic option.

I can't decide whether to replace with a genuine loom (believe the part number is 8E1 971 029) vs buying a herth+buss loom kit 51277117

Not too bothered about the price (assume new door loom is double the kit) but more about how straightforward and risky the job is to do. Replacing the door loom seems to involve extra disassembly and risks snapping bits that are working ok whereas the loom kit has the risk of sizing length of the wires and crimping but seems it might involve less unnecessary disassembly in hard to reach places in the door?

Any advice appreciated!
