Hi Folks,

New to forum - so hope this is posted in right section etc.

This thread seemed similar to the issues I have had with my C30. It’s a 2.0 diesel with Powershift box, had it a few years now - on 90000 miles.

Think this is the Peugeot engine. Without DPF additive tank etc.

Had some issues with the DPF sensor - which was replaced last year, and DPF cleaned by local garage. However; I have recently experienced issues with the engine running poorly under acceleration... almost like it is “dithering” between 30-50 mph. But also more noticeably on turning off the engine it “shakes” abruptly after turning off ignition. Not smoothly turning off - the engine rattles/shakes.

It starts fine, and idles fine - just shudders on turn off.

Recently had it serviced by a “specialist”, who ran some diagnostics - nothing arose apart from a historic EGR message. So had new fuel filter and Powershift transmission service etc.

The throttle body was cleaned/piping into it as well on the service, but still an issue after with the “shuddering” and “dithering” acceleration.

Also recently noticed a slightly “gassy” smell in the car occasionally.

Anyone got an idea on this?
