So had a read of Alex's thread
http://www.nissan4x4ownersclub.com/forum/showthread.php?t=22726&highlight=overboost&page=2
and thats sounds how I'd describe it. Its even done it in works carpark
from cold, juddering in reverse with no pedal, out of a space.
Was searching for overboost as occurs when engineer checked codes
did mention it and sort of reminds me how the zd 30tdi would go limp
at times, though with that would just ease of pedal and carry on, no
need to switch off and on again, well only to clear check light, but
on T2 no check light, no modifications to filter or exhaust other than
had a new flexi section installed in summer. Sometimes since I do
here more exhaust sounds, maybe even the turbo if giving it some?
Is over boost an issue on 2.7tdi? in past only noted it on 3.0tdi and
know previous trol owners were going to some lengths to deal with it.
