    DPFE (differential pressure feedback EGR) sensor

    is it prone to die?
    my W203 C220 CDI is starting to act up entering limp mode due to a P0401 code... valve working correctly but DTC cores keeps coming back to pending codes...

    is the DPFE sensor expensive?
    where is it located?
    is it a DIY job or an expert reserved only job?

    Have you had diagnostics via MB Star?

    Yes, the first time it was P0402 read at my local indie (I believe he has STAR software, because he identified several DTC codes referring to climate control flap controller motors...
    now I have an Autel Maxiscan MS509 and that is the one that I use to explore and delete error codes...
    as you can see in this post on another thread, I've been battling this issue for some time now... :
