    Default DTI Throttle Body Clean

    Hey all,

    Am I right in thinking the throttle body on my DTI is where the boost sensor plugs into? In which case mine is GUNKED UP!

    I'm getting limp mode regularly between 70-75mph in fifth a lot since Friday, I read the codes today and two came up;

    P0400 - Exhaust Gas Recirculation Flow Insufficient Detected
    (5A) - Not present
    P0400 - Exhaust Gas Recirculation Valve Feedback Signal Malfunction
    (F8) - Not present

    So I'm gonna clean the EGR up again as not touched it in over a year, but is it worth cleaning the throttle body part since I don't intend on cleaning any further, as surely the gunk gets further round the manifold and the rubber hose? I'll clean the boost sensor again as a few weeks ago I cleaned it just to see and it was caked, I needed a thin screwdriver to get it all out!!!

    TBH anything that is gunked up is worth giving a clean mate, just watch that you don't end up knocking the gunk further into the inlet.

    A word of warning though, try not to poke screw drivers into the boost sensor (or any sensor for that matter) there is a reason they have a little plastic cage around them
