Further to my thread 132314,
Further investigation of reduced power when pulling away in first gear and lack of power on hills.
Have had scan gauge check of EGR ok Injectors also all within specs ok.

In desperation drove vehicle into new estate at Airlie Beach (extremely steep) and climbed long hill in first gear at 800 to 1000rpm with obvious engine miss which disappeared when I accelerated above approx 1000rpm and then jumped as turbo cuts in at 1600rpm. Then took vehicle to local diesel mechanic told him of the problem and my frustration with nobody being able to diagnose problem.
Once again scan gauge showed no problem, but mechanic agreed to come with me (scan gauge still connected) up the previously mentioned road and there it was at around 1000rpm number 2 and 3 injector played up.
The injectors in this vehicle were replaced with genuine new injectors 60k ago (18mths ago) therefore no warranty (standard line prob bad fuel) and am looking at another $4k approx for another set of injectors.
So much for common rail technology!
6 year old vehicle been looked after, but with 232k on clock only worth 10k wholesale.
Changeover 30 to 35k
What to do, either way throw good money after bad.
Sorry for negative tone just feel that the market is ripping us off.
