Citroen Jumper exhaust back pressure sensor issue

Sounds familiar. I've got a Jumper too, though not a '21. Those symptoms scream exhaust back pressure issues. Have you run diagnostics to confirm?

Yeah, the diagnostics pointed to the back pressure sensor. So, what was it like for you? Did you experience the same?

Confirmed. Similar issues, turned out to be a defective exhaust back pressure sensor. Given the symptoms and diagnostics, it's probably best to get it sorted at a workshop. Expect around 245€ for repair.

Thanks a bunch! I appreciate the help. I swapped out the exhaust back pressure sensor, and now it runs like new!
