Beach interior lights fuse location - S131, S132, S133 etc.

[BeachBound]

We bought a 2015 T5.1 VW California Beach a few months ago, and I've been ironing out its issues as best as I can, including fitting a new leisure battery.

I thought this would fix the fact that the interior lights in the rear passenger/sleeping area never worked. However, whilst the 12v sockets under the 3 seater bench and in the boot now work, the lights in the ceiling moulding and the Poptop 12v socket don't.

I've spent some time perusing through the forums to chnical documentation, and it seems the likely culprit is fuse S133. I assumed this was in the fusebox under the passenger seat, but these are all labelled SF rather than S, and I can't find the location of S131- onwards in any diagram.

In the meantime, I've visually inspected all the fuses I can see under the seat and replaced one that had blown - a 15 amp fuse for a 12v socket away from the others.

Any ideas where I can find the S131 series of fuses? Are these just what's labelled as SF13-?

There is a cryptic mention of a coupling station on left of seat box (10 pin), but I'm not sure that is relevant to these fuses.

Thanks in advance

Have you checked the fuses in the dashboard fuse box?
