    P0400 is an EGR fault and a common cause of the issues you describe. If it doesn't respond to a clean, drop a new Delphi EGR on from eBay at ~£65, job done.

    With that said, They're totally different

    An EGR Valve, or "Exhaust Gas Recirculation" helps to reduce the levels of Nitrogen Oxide within your cars emissions and within combustion chambers. Helps by drawing in Carbon Dioxide as a coolant through this valve, blah blah yackady blah...

    A Throttle Body basically controls the ammount of air thats drawn into the engine. E.g when you press on the pedal to accelerate, the engine needs more air for combustion, valve is opened. Remove foot from pedal, engine needs little air as its in idle, throttle valve comes to a near but not total closure.
