Long shot but does anyone know what the silver pipe is in the first image with the hole worn in it?

General area of above image(in gap top right of intake pipe)
)
The aircon packed up last year even though it had been completely refreshed a year earlier as part of the head gasket recall. Ford insisted it just needed regasing and charged 85 quid for the privilege, due to covid (i.e. not going anywhere far!) and the crap weather I never really bothered checking but sure enough it's knackered again.
Just wondering if hole worn in pipe and aircon knackered are related! I've never had to regas a aircon system ever before and I'm forming the opinion when it had the head gasket recall done they ballsed the aircon up!
Be cool to know before talking to the not so local dealer (local shut down that did the last regas) as I don't want to go down the regas see what happens route again..
Cheers, Marc
