Not sure if it's just the lighter nights but I've started to notice that my jtd smokes when getting back on the throttle after slowing or when giving it some beans what would be causing this ?? Car does 84 miles a day 42 each way do should be getting hot enough.
Thanks in advance

What colour is the smoke? Black is an overly rich mixture, usually caused by turbo pipe boost leaks or a faulty maf, white is unburnt fuel usually because of a faulty injector which will be accompanied by a louder Diesel knock or burning coolant but you would notice a drop in coolant if it was and blue is burning oil probably caused by leaking turbo oil seals.

Check the main air supply pipes for leaks or splits, especially from the turbo to the intake, a leak here will cause black exhaust smoke.
