bump? - after 4 minutes?
The fault codes would be helpful for diagnosis.
Glow plugs on the high pressure common rail N57 diesel engines are not activated until <10C coolant temperature. If the vehicle is not misfiring at cold start then it should be ok. Generally glow plugs will not be utilised in Australia so even if all six glow plugs and the pre-heater display fault codes it will not detract from engine operation or performance.
The life expectancy of the DPF is ~250,000km. As the vehicle has completed less than half that distance the DPF should still be in good condition. Also no mention is made of trip duration etc. to determine if the regen mode is being activated or if "forced regen" has been implemented.
Plausible swirl flap can be an error attributed to when the flaps have been removed and the electrical control unit gives feedback to the DDE.
These are the correct part numbers for the components. Best to provide the last seven of the VIN to isolate the correct match:
12230035934 - glow plug
12218591724 - pre heater
