Ok so things have progressed again.

The power on long runs no longer drops to a weird limp.. this is since running a dpf cleaner through the system and a week of spirited driving.

It now sounds 'rough' and down on power - that would be the main symptom... if i accelerate, it always kicks down to get more torque it cant provide, whereas before the issues started, the engine would be smooth, and extra power was on tap without kickdown (its 400nm for goodness sake).

It feels slow, and sounds rough.
