2021 EQC
Hi all

i I have been receiving the dreaded coolant temp warning notification on the screen of my 2021 EQC, I am located in the Caribbean in Barbados so support/dealership help is not really a thing down here.

trying to diagnose the issue I found someone who is a bit familiar with them and he was able to put on his diagnostic tool to find the error. It was the code labeled in the heading but what he is unsure of is exactly which switchover valve it is that maybe faulty.

Is there anyone able to identify which one would be causing this fault? I know there is one valve to the back up top on the firewall and there is one to the left up top as well. This one to the left, none of the hoses going to that are hot.however all of the hoses going to the one in the back are hot except the hose traveling to the same one on the left from it.

Any assistance would be appreciated
