Can you please provide a full autoscan - as we need more information about the car. Also does it have Mit Silikat on the coolant bottle?

Removed.  Data from a clone/pirate copy of VCDS is not acceptable here.
I checked that bag in the coolant container it is in one piece (not torn and took it out for safety reason). But sth strange happens when running at night with lower temp. outside, temp from 27 to HI gave worm to very hot temp. at HI. At below 27 it is still not worm.

Funny... Scan in first post appears to have been made with a legitimate interface, but has a totally different HVAC module than the one in your Auto-Scan (AC Manuell vs. Climatronic).

Post an Auto-Scan from your car using a legitimate interface or off to the Hall of Shame you go.

Don't know what the problem is. I bought vcds on alixpress as many vag users do. I know it is not the genuine one but the money issue is the case.

HI, I'm curious, how much did the alixpress "vcds" cost ? (funds, how much) ?

You are always welcome here ..... so long as you use a legitimate VCDS interface. Perhaps you could use a friends or other individuals genuine interface? $199.00 USD.
