That would be a good cost saver 😂

So if we assume there is a sensor, how would it tell you if it's not working?

Warnings on the infotainment system, same as if any other sensors trigger…

There is a yellow sticker under the bonnet, the codes on the sticker for a heat pump is different to the regular non-pump heating system.

I don’t know the codes as I don’t have a pump.

Look under the bonnet for a yellow sticker near the front. If you have a heat pump fitted the refrigerant will be R744 (CO2). If not then the refrigerant for the standard A/C is R1234yf.

Is that correct? Is there some better manual that tells us what is reported via the infotainment system?

You're expecting a list of all the possible error warnings to be published? Well that would make sense I suppose but given that VW dealers clearly have no access to one, I doubt it exists.

This is my first foray into dealing with VW dealers and so far, I'm not that impressed. I wouldn't say they are worse than any other car stealer but I hoped for better after the Diesel debacle.

I haven't seen anyone ever show a "heat pump not working" screenshot.

I would be very surprised if a fault with one was not shown given all the stuff that is shown.

You might get this pop up on the display behind the steering wheel:

That's taken from the online manual which you can access here: https://www.volkswagen.co.uk/en/owners- ... nuals.html

You might also get a "report" shown on the infotainment system.

Let's hope we never see it.
