Right so this is my second post and I need help

the 12v sockets on my Octavia don’t work they used to which would indicate a fuse has gone possibly? 

I have tried the one in the boot too and that’s the same 

where Can I find this fuse and is it easy to get to? 

It’s a mk3 Skoda Octavia 1.6tdi elegance 

absolutely love it apart from not being able to use the air pump currently and being on the side of a road whilst trying to fix a puncture and it not working was not the best experience going. 

I don’t know the answer, but my first port of call would be the user manual.

Don't have it near me but pretty sure there is a section that specifies which fuse is for what.

The 12V sockets are on fuse no. 40 (as per diagram above) in the dashboard (not those in the engine compartment). Presuming your car is RHD the fuse box is on the passenger side behind the glovebox (simply clever...). Below is a link to a video showing how to get to it
