Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
Ok, there are few possible causes -
fuel injectors worn and allowing too much fuel
high pressure fuel pump faulty
worn piston rings
Because there doesnt seem to be a loss in performance, I more suspect the injectors or pump. An injector balance test and fuel pressure test need to be done in order to determine which is at fault and then make necessary repair
Ok, that being the case, I suspect the high pressure pump was calibrated and set up incorrectly out of the factory. Sometimes you can get away with simply recalibrating it with a scan tool, and other times it will need to be partially rebuilt to set it up properly.
