    i removed my egt sensor today after finding where it was located and it looked kinda corroded, so i wire brushed it. put it back in and took it for spin. car felt better, no code but while i was logging, temps got upto 950c. is that a problem? didnt really push it to the limit tho

    950deg is fairly normal when ragging a K04 turbo'd car but if yours threw that code (I have seen this one myself but for different reasons) I would suspect (as Bill has already said) the EGT sensor is on its way out... intermittent means just that...
