    P0621 is an alternator related issue (actually means alternator warning lamp) So I think that one is best left to an autoelectrician to check.
    P0340 Is our favourite camshaft sensor failure, does the car run in limp mode at all? wont rev etc?
    P0380 is glow plugs/glow relay problems

    I find that at about 15-18,000 revs the ar can sometimes loose slight power, nothing to worry about but not right.
    It also has issues starting as its not strating first time?
