Big dirty plume of black smoke upon ignition??

What could the above indicate in a 2005 Diesel Passat, or any car for that matter. After the initial burst of smoke, everything is fine. Occurs regardless of outside temperature.

Engine is full of soot and coked on carbon?

It's from my Dad's car. Would it be advisable to get it looked at?

Check air filter that the main cause but probably needs a good service

Has the car been chipped ? This causes over-fuelling and may be a cause.
Could also be an Engine Temp Sensor fault.

All I would do is take it for a good hard drive, revving it high through the gears to try to burn off any carbon build up as RS2K said and then maybe get an 'Electro Diesel' place to hook up the diagnostic computer and see what shows up.
