Sidelight not working. (Not a bulb issue)

Hi all.
I put a new set of canbus compatible LED sidelights in today, which threw up a problem with my drivers side not working. I did an ECU reset,still not working, downloaded the workshop manual to look for a fuse, never found it, wtf is wrong...?
(Tried all the bulbs to see if it was one of the LED's, but no).
Did a few searches, but most relate to the fitting of new bulbs and not where a problem might be.

Any pointers greatfully accepted...

Could be a loose connection in the headlight for the sidelight try wiggling the wires for the side light and see if it starts working

Is it just on LEDs, or is it not working on normal bulbs too?
