Air Conditioner smell?
I have the '09 W211 and I have had it about 3 months now...
On occasion, when I turn the A/C on, it has a faint chemical smell. I have not experienced this in my last BMW 5 series or my Acura TL.
Anyone else experience this? Any known cause? I hate to take it to the dealer for just that, but it's giving me a headache at times.

Thanks
Supposedly there was a service bulletin about this, and the dealerships can do a treatment on it. (similar to previous post) Though my dealership acted like they knew nothing of it.
IIRC it's actually mold forming because condensation just builds up -- it's a design flaw.
I was able to remove the smell from mine by replacing the cabin air filter.
