The coolant has always been pink.

Does that mean that I do need to be putting G12+ in there?

yes

They said half filled, to my wife on the phone, but it was higher than that. About a couple of inches from the brim.

At the start of all of this, I'd had the red light. So, I was carefully looking for that, and the temperature gauge, while we were driving.

The temperature spent most of the time around the middle mark. Mostly slightly below. Occasionally a bit above. Is that normal?

Great, thanks.

I think most would agree that the temperature gauge position you mentioned is ok, my gauge normally sits just below the half mark when driving along and only goes halfway and slightly over when stuck in traffic on hot days.
 

Mine stays just under half way travelling at 55 to 60mph if I go any faster the temperature starts to Rises so I back off the accelerator and all is cool again only because the people on here told me how to drive this Van's

No! No need, it is a diesel as mentioned before.

He already has pink in

Add blue

You get chemical reaction and jelly..... at least that's my understanding

Not all pink is G12! I used to use a pink liquid on my Ford engine as specified but it wasn't G12 - it was produced long before 1997 when the G12+ came on the market for VW engines. I will have a look to see if there is still an old container in the workshop.
Waste of money putting G12/13 etc in a diesel.

I wasn't providing advice about what coolant to use in a diesel, i was providing advice as to what coolant to use in his van, which has just had fresh pink coolant put in.

I wasn't suggesting topping up with blue if there's already pink in there. I was just saying diesels don't need the expensive pink stuff, it's a waste of money. If he's just had new coolant put in, ask garage what it was, and if they put in something other than VW recommended spec, maybe ask them why.
Also OP, you pulled over on the motorway because you were geysering coolant, took the expansion tank cap off and let lots more go, but didn't top it up again? And it was then ok for the rest of the journey?

Yes. Exactly right.

I was surprised. I had water, ready to top up, but the heat and levels remained fine.

Have you checked the levels since, as what was lost must have come from somewhere, so after cooling down completely you may find the levels have dropped significantly. Also at what point does the electric fan kick in, mine normally switches on when the temperature gauge wanders just past the midway position.

I say again, go to a different mechanic , the current clearly hasn’t got a clue how it works !
it’s over pressuring from your description, either the head or head gasket is at fault unless you know different I would be budgeting for this

I said that. Wondering if they did any sniff/chemical tests? I suspect not. Just (nearly) fill it up and send it out by the look of it. This one may run and run (possibly until it doesn't ).
