Does a Renault megane have egr valve?

Yes, the Renault Megane has an Exhaust Gas Recirculation (EGR) valve. The EGR valve is a part of the vehicle's emission control system that helps reduce the amount of harmful nitrogen oxide (NOx) emissions produced by the engine. It works by recirculating a small amount of the exhaust gas back into the engine's intake, which helps to lower combustion temperatures and reduce the formation of NOx.
