Have an A4 2014 1.8CJEB Manual, which I picked up ~9 months back. Came with no air con and had rough idling but still a good price.
Had it scanned back then and sorted the idle issue with the camshaft adjustment magnet.
Now sorted myself out with VCDS as its make sence in the long run, so forgive me if I have missed something obvious.
Not sure if they used VCDS or another tool but it logged this:
VAG03220: Climatronic Refrigerant shut off valve open circuit/Short to ground static
I have since scanned and have the following:
15455 - Thermostat for Transmission
P19A0 00 [00101111] - Short to Plus
03220 - Stop Valve for Coolant for Climatronic (N422)
009 - Open or Short to Ground
0457 - Central Electronics Control Module / BCM (J519)
013 - Check DTC Memory
0256 - A/C Pressure/Temperature Sensor (G395)
008 - Implausible Signal
looking in to (03220) I see the code linked to Coolant Blocking / Solenoid Valve 4H0121671B/D faulting and leaking coolant in to the wiring that by the gear box on the left side/UK passenger side.
I have checked and I have the updated 4H0121671D part and the plug and connector look dry and clean.
I have seen (15455) also related to the same part.
Now I have found two of the valve’s, one by the gear box and one in the plenum chamber. Is there a way to identify which valve is ID’ed as N422 or are they both called that?
Can the part fail without leaking coolant past the connector and still cause the same issue?
Is there anything else I should try and test
