   wahhh, very confusing post.
   
   Mk1 vts = single plug ecu
   mk2 vts = 3 plug ecu.
   
   you dont need to mess about with lambda sensors but FYI theyre in the exhaust manifold and the 2nd is after the cat iirc.

   EGR valve?
   
   Pretty sure this was the cut off point for single lambda.
   Might be wrong though.

   Exhaust gas recirculation valve.
   
   If you have one it will be located above the exh manifold.
   Would post you a picture but mines a mk1 vts engine so no egr.
   
   Post a pic of the engine might make it easier for us to determine which one you have.

    Yep certainly looks like it, if you can get the engine code and your friendly with citroen they should be able to clarify this.
