Rifter Lukewarm Heating

I had a similar issue with my old Renault Megane. Heating was terrible, and it turned out to be a blockage in the cooling system. Is the engine temperature gauge reading normal, or is it running cooler than usual? Have you checked the engine coolant level recently?

Temp gauge seems normal. Coolant level looks okay too. Did yours throw up an error code, or was it just the rubbish heating? How did you figure out it was a blockage?

Mine did show an error code eventually, something to do with the heater core. I tried flushing the system myself, but it didn't really help. In the end, I took it to a workshop. They diagnosed it as a faulty water valve causing the blockage. Best bet is to get it checked out by a professional.

Appreciate the advice. Took it to the garage, and you were spot on – duff water valve. They quoted 95€ for the repair, which seems reasonable. Getting it sorted tomorrow!
