It s leaking from the copper pipe connected to the pump.

I run the risk of being told I'm wrong, but in my opinion you will need to be Gas safe registered to have any advice here.

They do there's a tb out what homeowners can do

Aslong as they have a seal like the baxi 105 has eg case doesn't form the seal they can do what they like on the wet side aslong as they don't take the seal off

So as long as the op knew this In the first place, and any others that care to follow suit, (as long as they don't make a mistake and open the wrong boiler case, or mix up which one they thought was there's, because they may have looked at a PDF and got confused by the GC number), it shouldn't really be a problem then. ?

correct normally fixed on with no screws or plastic ones thats how you can normally tell theres a secondary seal/cover

if that makes sense

You can see the water on the top of the AAV in the posted photos.

Jazzy - tighten down the little cap on to stop the water leaking out, dry it out with a cloth to check it has stopped & then do yourself a favour & call a Vaillant boiler guy.

I see the theory, but I would not want to giving advice, unless I knew there was a level of proven competence. If you're happy to, then fine you've certainly helped me out a few times and im sure the advice you give would be sound, my only concern would be the ambiguity it signals for any other op's.
