Well I am confused, I have recently purchased a Discovery 2 commercial (51 plate 15P engine) apart from requiring a new clutch I had the smoky cold start issue which I put down to two possibilities:-
MAF sensor or Injector seals, I also noted it was VERY smoky when idling for a long time and smoked like a Trooper (excuse the pun!) when pulling away. It never smoked on over run or whilst driving. It goes like a train and is not down on performance - the most poky TD5 I have owned (I already have another one overseas in Africa).
I have changed the following:-
Any way funny thing is it flew through its MOT yesterday - I was genuinely shocked especially as I was smoking all the way down the road after 10 minutes of idling in the MOT station but the emission readings are well below spec. cylinder balance from Nanocom is a bit hit and miss on cylinder 1 especially in the 1100-1600 RPM range anything up to +28 (not under load though when its fine).
There seems to be mixed feelings around TD5 injectors some say they are bullet proof others bemoan them. I have ordered a second hand spare but wanted the forum thoughts for me and others?

I have changed the following:-
- Injector seals
- MAF sensor
- Turbo bearing and seals
- Given it an Italian service got KMH and MPH mixed up on the motorway and thought I was doing the speed limit to clear intercooler of oil.
