The B6 I bought came with 'clicking noise' (never seems to stop) when I bought it.

VAGcom codes below.

Since there are more than just one motor/solenoid involved: could it be that something is 'systematically' wrong? Maybe wrong softcoding, or wrong HVAC control module installed by previous owner?

Or wire pulled off (maybe while installing aftermarket radio)?

here are the codes:
