Help needed locating low-pressure A/C valve

[B3Svert]

A/C seems to have given up the ghost, despite Kwik-Fits best efforts at a recharge. Before I take it to a garage wanted to have a go at locating the problem myself with a sealer detector kit.

Problem is - I have no idea where the low-pressure air con valve is within the engine bay! Car is e46 convertible, any ideas where it is please?

Cheers
