Renault Master EGR Valve Symptoms

My 2011 Renault Master diesel is having EGR valve issues at 66526 km: reduced power, check engine light, smoke when accelerating, rough idle, high fuel consumption, jerking, and a hissing sound. Anyone else seen this?

Sounds familiar. I had similar issues with my Renault Trafic. Check engine light, loss of power, the whole shebang. I was thinking it was a blocked catalytic converter or something, but might be the EGR then...

Did the symptoms align with mine? Specifically, did you observe a hissing sound during acceleration, indicating a potential pressure leak around the EGR valve?

Yeah, the hissing was there too, now that you mention it. It was more noticeable under load. Honestly, I'd get it checked by a pro. Could be a number of things related to emissions, but EGR seems likely. Mine needed replacing in the end.

I appreciate the insight. I suspected as much. An inspection confirmed the EGR valve is indeed defective. Repair will cost 355€. Thank you for confirming my suspicion.
