V90 weak heating water valve

V90 2016 gasoline, heating weak, error logged. I've got a 2016 V90 with the gasoline engine. The heating output is too low, and there's an error stored in the memory. Suspect water valve, maybe cable/plug issue. Anyone seen this?

The coolant level and engine temperature are normal, ruling out those as causes. The issue was confirmed to be a faulty water valve, which was replaced, resolving the heating problem.

I had a similar issue with my V90. Heating was intermittent, and there was definitely an error code. Did you check the engine coolant level? Also, is the engine reaching operating temperature normally?

Coolant level is fine. Engine temp seems normal. Was your issue definitely the water valve or something else?

Given your description and the error code, it points to a faulty water valve or a connection problem as you suspected. Given your expertise, I'd recommend checking the connections first. If that doesn't resolve it, a workshop visit is probably in order. Replacement looks unavoidable.

Thanks for the confirmation. It was indeed the water valve. Replaced it, and the heating is back to normal. Total cost 95€.
