Hi,

Assuming no combustion chamber or fuel delivery faults, most turbo diesel engines exhibits this. The delayed is referred to as turbo lag and the smoke is fuel not completely burned since the fuel system tends to be a little rich when the turbo has not attained boosting RPM. Other than to have your injectors cleaned/replaced, the injector pump re-calibrated and/or the turbo checked for leakage, nothing much could really be done. Alternatives are to use fuel additives, re-check of the computer's map/software and/or change of driving habits. The idea is not to floor the accelerator until the turbo has reached the designated RPM where it kicks in.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
