Oil/grease smell through vent

[chicletgrin]

I have a 2006 C4S Coupe that has about 2400 km on it, and since I got it a month ago there's a really acrid oil or grease smell that comes throught the air vents. I have noticed that is is worst when the heater is on. I took it to the dealer today, and they can find nothing wrong with it, and suggested that it could be excess undercoating (which they tried to reduce). They also replaced the charcoal filter and sprayed disinfectant into the A/C. Unfortunately it didn't work, the smell is still there. They figure that this is normal for a new car, and should subside over time.

Has anyone else experienced this? Is this normal for a new 997? This is my first Porsche, but no other vehicle I have owned has ever done this.

Any ideas would be welcome.

Hmm... there should not be anything hot enough up front to produce that smell in the cabin air intake.

Is the smell in the front trunk?

[chicletgrin]

No, the trunk doesn't have that smell, or if it does, it's very very faint. What comes through the vents is considerably more noticeable.

[Loren]

Fresh air comes in from near the front winshield so the smell must be inside the filter AC/heating housing.

Take the car out and drive the wheels off it for about a week and the smell will go away on its own. Its probablly all the assembly oil and assorted fluids slowly burning off.

:lightbulb: Had this happen on a 2004 MB 500 I used to own, it was the A/C compressor leaking oil into the evaporator and over time it created a film in the vents causing the oily odor.
