Hi..thanks for your reply..
If there are no codes as such then it maybe well worth at least looking into the EGR system & removing the EGR valve to clean it out as this can give the type of problems you have - excessive smoking under load or taking off from a standstill - so if that hasnt been checked out as of yet then that might be one place to start..ensure the valve does work where ever take the vehcile to have this carried out..a simple clean maybe all its needing as these valve tend get coated in soot and thus the valve isnt able to open a shut and cause problems like you have above..
