Cayman hazards not working

[DIW35]

Just put my Cayman 987 through an MOT and it transpires that the hazards aren't working. Left and right indicators are fine, it's just the hazards. I thought it might be a fuse, but the fuse box diagram is less than helpful as it doesn't list a fuse for the hazards and I'm not savvy enough to interpret which one it might actually be. That's assuming, of course, that it has it's own fuse.

If it's not the fuse then I guess the only other culprit would be the relay or the switch itself, but I'd rather start by checking the fuse, if anyone can point me at the right one.

I should add that all 4 indicators flash when locking/unlocking the car, so it's probably unlikely that it's the fuse or the relay, but I should be thorough.
