Stop Valve for Coolant for Climatronic (N422)

[sacha35]

Hi Guys hoping someone will be able to help with this one.

Uk Audi A4 B8 2008 2.0tdi without auxiliary heating

Did a routine scan on the car and found it to have fault in Address 08: Auto HVAC:
Fault 03220 - Stop Valve for Coolant for Climatronic (N422)
009 - Open or Short to Ground

Looked up Climatronic (N422) on Elsa for location but for the life of me I just can not find the N422 solenoid (needle in a haystack springs to mind).

Hoping someone has come across this problem on a B8 and can guide me to the location.

Many thanks in advance.
