Hi code 16407 is this Bank 2: Camshaft B (Exhaust) : Position Actuator Malfunction, which could just be a software isue thhat you will have to go to a main dealer to have the engine ecu software upgrade done, i must ask you at this point have you had the cambelt changed and if so has this fault occurred since then , is so you may find the cambelt timing is incorrect, if not then poss a software upgrade will sort that out. As for the other code 17550 - Load Calculation Cross Check: Lower Limit Exceeded, this could be poss caused by a dirty throttle body or defective MAP sensor, i hope this helps Chris
