map sensor is on the top hose on the right as you look in the engine bay between engine and battery/diesel filter.Common one for this is a faulty turbo which causes overboost which then makes car go in to limp mode.by stopping and starting it resets limp mode.Usually worst when flooring it up a long incline/hill.usually causes limp mode lack of power
