Wiring a 2gang 2way switch / light will not switch off

[Taylortwocities]

…and wire it properly.

I have wired the intermediate switch, but still no joy. Any help guys?

 

[Jamiejones]

Any help is much appreciated

I am assuming the Brown, Black and Grey are the new wires -

It looks right - assuming -

there is a Red in common at the other switch,
out of the top of the picture the Brown is connected to the Red of the RYB cable and
the red and black connected to the new switch are from the same cable.

There is far too much copper showing. There should be none.

The new intermediate switch is in the first of the two photos, right?

If you tell us how the switch that was in the position now occupied by the intermediate switch was wired when it was all working, then we can tell you how to connect it now. Otherwise we have to guess.

No we don't.

It was the two-way switch with the Line and Switched line.

Here guys - minus my 3core black/brown/grey.

Sorry, I'd forgotten that there was an earlier photo of the wiring.
Hmmm....

Please confirm.

 

[Jamiejones]

Please confirm.

Brown in common at the other switch. Since the new wiring is Brown. But connected to existing red on the intermediate switch by block.

And yes the red and black connected to the new intermediate are from the same existing wire

Brown in common at the other switch.

No, the other other switch. - the one you have not altered.
