So I opened my bonnet this morning to install a relay and I found these just sitting in the water gutter section of the engine bay. I don't know how long they've been there for or what the hell they are for.
I'm just hoping it's not a part the mechanic left out when they did the major service.

Any help would be awesome!
They are made of hard plastic with a rubber oring on them.

What did the major service consist of?

Are they plugs that are in new a/c components?

It was the 200k, so timing belt, plugs, oils, coolant, new timing cover gasket and a general checkover of the underbody, suspension, brakes etc.
but I did get a new AC compressor and AC clutch put in, and the regass that goes with it.
The car has been running fine and no oil leaks or loss of cold air.
The parts don't look used at all, ones a little squished, probably from the bonnet though.

Yep, plugs from the new A/C compressor.

Oh okay, so obviously not needed then. Good to know!
Cheers guys!
