Megane Overheating Bypass Valve Error

My 2002 Renault Megane with a diesel engine has been overheating lately. I've got an error stored related to the bypass valve. Mileage is at 196542 km. Any ideas?

Summary of the thread

A 2002 Renault Megane with a diesel engine was experiencing overheating issues, with an error related to the bypass valve. The problem was initially suspected to be a vacuum leak in the exhaust system, potentially causing power loss. However, after professional diagnosis, it was determined to be a sensor issue causing multiple errors, including the bypass valve error, and was resolved without cost.

I had something similar with my Megane. Overheating and a stored error could be a vacuum leak in the exhaust system. It might be a consequential error and not the actual bypass valve. Does the car also feel like it's lost some power?

Power loss... possibly, hard to say for sure. Where should I start looking for this vacuum leak?

Honestly, chasing vacuum leaks without the right tools can be a pain. Since the error memory mentions the bypass valve, it's best to take it to a workshop. They can do a proper smoke test of the exhaust system and pinpoint the exact problem quickly. It'll save you time and headache in the long run.

Thanks, I took your advice and went to the shop. Turns out it was a sensor issue causing a cascade of errors, including the bypass valve one. Repair cost: 0€. All sorted now.
