Runs fine at idle. No whinning, only when turbo spooling down [i think]
Normal smoke for a diesel, but smells very chemically since hose was replaced.
Engine runs fine when stationary, but coughs on the way if i floor it.
Hesitation under light throttle, judders in controlled smooth acceleration, but only a minor cough in hard acceleration.
1st gear in particular, if I floor it, there's a delay where I'd expect the boost and it comes in a big handful all at once after a cough.
