High idle and fans running at end of journey - no regen

157€ for the pleasure, 810g emptied, 830g filled.

Which means this not-so-insignificant amount of money goes for 20g of gas (plus labour)?

Yes.

Of course the expectation was that after 7 years loss of refrigerant would have been more significant. I suppose the lesson is no reason to do this service unless you start to notice AC not being what it used to be. I (foolishly) had it done as the dealer here recommends the service every 4 years.

Have you noted at which ambient temperature A/C is cut off?

No, not yet. Now added on my to-do list

Also any guesses why it does that? I think the freezing point of R1234yf is well below -100°C, can't be due to that. Too much condensation and it would be forming ice bergs?

Never thought about that...
Oh, didn't realise that some variants of T6 already had R1234yf - mine (panel van) is still running on R134a.

At last A/C service (after 2 years from previous)

R134a​

drained 555 g​

oil 0 ml​

refill 605 g​

The dealer might have changed the refrigerant type like they did with the preferred oil couple of years back.

Have to dig a bit to see if I can find which one was used from the factory.

”Compatibility: R1234yf can be used in most existing R134a systems with minimal modifications, making it a practical choice for many manufacturers.”

Browsing through the build sheet noted this one - my van has indeed come with R1234yf from the factory

I made the mistake of reading this thread with a cuppa this morning…..my wee brain hurts now!!!

I think I’ll take the dogs for a walk so I feel a little less inadequate!!!

Same here. As far as I know it’s a bit more eco friendly but helluva more expensive than traditional R134a.

AC guy told me that generally everything post 2017 should be newer 1234 gas

I will second this.
EU introduced regulation for all vehicles manufactured after the 1st of January 2017 to use R1234yf as the standard refrigerant for air conditioning systems instead of R134a.
