Fuse 64 still intact, but opening the lid revealed the obvious culprit...
I my haste to get everything plugged in, the SAM seated correctly and the lid back on before the rain filled the box up, I didn't quite get the fuse holder locked in, so it was sat cattywampus and hadn't seated any where near it's correct position.
At a glance last night it looked OK, but having driven the car today it was floating free.
My suspicion was a loose plug on the SAM or a pinched wire where the box bolts to the firewall, and although WIS would have lead me to the fuse as a possibility, it was a surprise that any of the Airbag gubbins is fused.
Still, a nice easy fix even if it was self inflicted 🤦
if that’s the case be careful when it rains or you wash the car - or it will fill up the insides of the car
that part of the car can sit with >5 litres of water sloshing around and it shouldn't come in the car - if you check my other post in the front corner is a BIG 1/2" drain hole - and at the back some mad screen drain funnel garbage - same on the UK drivers side

Rest assured both scuttles are now as clean as your pics, learnt that lesson about 17 years ago on an Omega😉
the silly internal air intake on the Omega allows the UV to eat a main loom's fabric trash loom wrap that Germans love to use.... the UV made it all fall off and it blocks the drain - had mega rain one day and it filled the passenger foot well with about 10 litres of water (I'm on a slope so it was all at the front of the footwell) popped open the junk pollen filter access cover - scraped arm to death and fished out handfuls of crud loom tape from the quagmire - 15 litres drained on the outside - dried carpet car was fine for another 10 year - no mental canbus junk to deliberately play up on a GM car
Both my Omegas were way more than twice a car then this junk S class is - ride comfort and seat comfort is leagues ahead of any 221 - I drove my old one to the junk yard after it did nothing for 18 months after getting rid of a mint 335d with active cruise (BMW radar was way better than the 221 mess) and got this S class - to this day I should have driven the S class to the junk yard and kept the omega - I couldn't believe how much better it was to drive than my mint 42 k mile formerly £140k S class w221
