Jumpy EGR Valve Issue

Citroen Jumpy gurus, my 2021 Jumpy diesel has lost half its power. 70816 km, check engine light's on, smokes when I accelerate, runs rough, drinks fuel, and jerks. Plus, there's a loud hissing noise under acceleration. I'm pretty sure it's the EGR valve. Anyone else had this happen?

I had a similar issue with my Jumpy. Reduced power and rough running were the first signs, but I didn't experience the smoke or hissing. Did you try any diagnostics, like reading the error codes?

I plugged in my OBD reader and it's showing the EGR valve as defective. Just wanted to see if anyone else had the exact same symptoms before I start ripping things apart. Did your symptoms appear suddenly, or was it a gradual decline?

Mine was quite sudden, yes. Given the error code and your symptoms, I'd say you're on the right track with the EGR valve. Probably best to get it checked by a workshop though.

Appreciate the confirmation. I took it to a local garage. Turns out the EGR valve was completely jammed. New valve fitted, and the total was 355€. Runs like a dream now, no more smoke or kangaroo impressions!
