Fault code B109C-15 - Drivers door puddle light

Advice please if possible, been round in circles a few times on the car and the internet !!

2014 SDV6 HSE.

Doing usual monthly(ish) code check threw up B109C-15 - drivers door courtesy light.
Found puddle light not working, bulb blown - easy i thought - yeh right.
New bulb - nope still doesn't work, try bulb from working light in passenger side - nope.
Try working bulb holder and bulb from passenger side, nope still not working.
Try voltmeter - no voltage at bulb holder.

Door has not been damaged.

Any ideas ? Tried the suggestion on this forum of opening and closing doors etc - fault been around for a week now so nope there too. Wondering if it's one of those weird land rover resetting procedures ?

Any suggestions welcome Smile

Thanks

When unlocked, does the bulb give a very brief flash? My previous 2014 D4 did this. Unfortunately I traced everything back to the a problem with the cjb. Never did fix it before it was sold.
