Air conditioning barely working

[HPsauce]

You just don't notice until the weather gets hot!
I suspect that at the very least it needs a re-gas, the last time it had that was at A8parts several years ago during an annual meet! It took quite a while...

But what specific guidance do I need in terms of where to get this done and what they need to know?

There is just one fill port thats accesible and everything can be done through it. Most cars have 2 and most mechanics have only seen cars with 2.

That sounds very familiar, thanks.

Next question from the untrained - where is the fill port and what needs to be removed to get at it?

Edit: Looking around I found something that "might" be it under the scuttle panel between the air intake box and ECU box.
Looks really awkward to get at though, or is there a trick to it?

Is this it, the out of focus knurled grey knob visible just above the screw, lowish centre right?

Thats the low side port and is unusable, partly because its impossible to reach and mostly because its a unique fitting which no one has in the UK. Fill from the high side on the condenser only. I just posted a bit more about this in Lancia2000's thread

Thanks MJ, where is that exactly, or would a garage know where to look?
And what if anything needs removing to comfortably get at it?

[MikkiJayne]

The high side port is on the condenser in front of the radiator, left side looking at it. You don't need to remove anything other than the cap

Sorry, being an unobservant dimwit, looking inside the engine bay!
This is it very obviously:
