Mercedes C220 CDI Limp mode and power loss

Update: faulty pressure differential sensor and clogged DPF

[@justaaron5182]

My father has a 2009 mercedes e320 224hp, it runs good and hits boost pretty good, but whenever the engine light comes on, it loses power. We cleaned the turbo, changed the intercooler, new fuel pump but nothing, it just says that the right dpf sensor is the problem. We checked it and got a new one but the error just comes back after we remove all of the error codes.

thanks for the info. Looks like our problem isn't fully solved as well, replaced DPF sensor but there is still a noticable powerloss from time to time. I'll make sure to post an update once I figure it out.

Problem came back after a while and eventually had to change the dpf itself

Vacuum/boost leak.

[@2guyswithcars290]

Or maybe a lot of back pressure due to a clogged DPF since it has given DPF fault codes last week
