Megane Heater Blowing Lukewarm

I've got a 2020 Renault Megane, hybrid engine, about 51,642 km on the clock. Lately, the heater's been blowing lukewarm at best. Plugged it into a code reader, and it's showing an error related to the water valve. I'm thinking maybe a valve blockage? I even checked the hoses, but I can't spot any obvious coolant leak. Anyone else wrestled with a dodgy automotive valve on these things?

It's certainly possible the valve is faulty. Have you checked the cable and plug connection to the component itself? A defective connection there can cause similar symptoms and throw that error code. Is the error message consistent, or does it disappear and reappear?

Good shout on the cable and plug, I'll definitely give them a wiggle and a check for corrosion. But if it IS the valve itself, is that a big job? I'm assuming it controls the flow to the heater core, so could it be a simple car valve replacement, or am I looking at a whole day of dismantling?

If you have already checked the connection, and the error is still present, then the valve is defective and must be replaced. This is a relatively minor repair, with costs expected around 95€. However, it is essential to have the functionality of the component checked again after installation.

Thanks a bunch for the advice! Turns out the valve WAS the culprit. After checking the connections and they seemed alright, I decided to bite the bullet and get it swapped out. Heating's back to normal now! It cost me around 95€ at the workshop, just like you predicted. Cheers again!
