this sharran 1.9tdi 1996 has the mil often coming on.only logged code is the map sensor (in ecm). i have cleaned out and checked the pipe,sent the ecm to atp who said nothing was wrong with it but i asked them to replace the map sensor anyway.there is a good possitive pressure at the pipe when engine speed is increased. just need some ideas as to other possible causes for the code been flagged if anyone has any ideas? i.e is there a boost pressure control valve that could be allowing the map to go out of limits?? many thanks sean
