Hi i own a Nissan Primastar 1.9 dci 2008 model 9 seater minibus. My vehicle will not rev up at all. it idles on JUST above 1000rpms. The glow plug warm up warning light on the instrument panel remains on. according to the manual when this light remains on it signals that the vehicle has switched to limp mode due to water in the diesel or an electronic problem. The Nissan workshop have used their diagnostic machine to find the fault and the first reading that it gave was: not reading the electronic pedal then the airflow meter.This was all changed and still no acceleration. they have checked the wiring for any burnt or bad connections and still nothing. The mechanics have said there's nothing else they can do as they just cant find why the car wont rev up.
PLEASE CAN ANYONE GIVE ME SOME ADVISE ON WHAT NEXT TO LOOK FOR OR CHANGE OR DO THAT HASNT BEEN DONE. MY VEHICLE IS STANDING FOR 3 MONTHS NOW AND I AM DESPARATE.THANK YOU,
