Well i've yet to have my diagnosis but after 150,000mls im sure mine must be close to needing new / reconditioned injectors as it too keep jumping into limp mode

BUT

My limp mode doesn't sound like other peoples limp mode off meg
Mine has been remapped and when it goes into limp mode it still has i'd say 130bhp but no torque

Also when in limp it sometimes just cuts out completely and needs restarting , and that can happen in the fast lane of the motorway or even on an overtake manouver * the sooner i get it fixed the better really , but once done i'll save up and chop it in and never touch another one for a few years .
