Blue Smoke on nearly new W211 Facelift E220 CDI

[nerooo_07]

Hi people.
I left the car for 3 minutes on a average gradient slope, with the gear in P handbrake in, engine on. I went inside a friend house.
After I went back to the car I got scared how much blue smoke was coming out from the exhaust pipe.
I have the car for about 10 days.
How it's possible if the car has only 42 000Miles

DPF regeneration? No smoke after that?

What is that mean sir? Was smoking only on the slope.

Your car may be fitted with diesel particulate filter (car data card would tell if fitted); it collects like the name says small particulates (you'll notice that your car basically does not smoke if otherwise ok), and ecu empties it according sensor data collected. Stuff inside the DPF is burned by feeding extra fuel to cylinder which goes to exhaust. DPF may be failed due to turbo failure etc. Star diagnosis would give info about the condition of DPF.

The car has DPF sir.

Peoples, is it possible on such car almost new, blue smoke while standing downwards on a slope?

I mean now, only when Air Conditioning is on. Lots of blue smoke. Please

I'd be more concerned that you left the car and went into your friend's house with the engine still running!

possibly less of an issue in Norway

Pretty much the only thing that can cause blue smoke is burning oil. Only happening on a slope, and happening when the engine's put under load?

My guess would be the turbo seal worn, or the engine oil overfilled.

Cheapest things first - check your oil level. If it's too high, correct the level and see if the car still smokes.
