    Driving down a bypass section, and my 330d Sport Auto suddenly lost all power and momentum... seemed to rev really slow, as if it was in "safe" mode....
    pulled over, then set off again, and car seemed fine..

    Code read it, only code coming up is P0401 EGR insufficent flow...
    Going to take it (EGR) off and clean it... could it possibly be the MAF too ??

    Did you turn the engine off then restart it and found it was fixed? you really need to get the fault codes read for the car, if no codes are stored then the engine running live data needs checking, if the problem becomes more persistent then you could disconnect the MAF plug and see if it improves things.

    Otherwise the fuel pressure needs looking at.
