This is my first Mercedes car (2009 C300)that I've purchased. I traded a 2001 BMW330i that I had for approximately 10 years. I fell in love with the car. It looks great and rides great. Unfortunately....I have been dealing with this annoying waxy or crayons smell which the dealer is having a difficult time in eliminating. They've treated the evaporator coil, changed the cabin filter, scrubbed the carpets and performed an ionization on the interior. The original smell is not as strong but is still there and very annoying. Ay similar experiences or suggestions?
What could be the cause for an annoying interior odor in my car? on 2009 Mercedes-Benz C300

Have they tried 'frigi-fresh'yet? OR you could burn some sage leaves in it (although then it'll smell like dope).Alright maybe not the greatest idea. After ten years of the same car your nose 'Knows' the beemer.If the car smells like other used cars on the dealers lot where you bought it , then maybe they should stop cleaning it and give your nose a chance to 'bond with the Benz'. Good luck I hope you start enjoying it soon.

I was told my my local mercedes service tech that when running your a/c condensation will accumulate over time in the vents throughout the car. When it is not allowed to dry properly residue builds up in the ductwork and each time you turn your a/c on the cold moisture activates the smell in the ducts when starting your car. He advises in any car that before shutting off your a/c that you run the fan without the a/c going for a couple of minutes to dry the ductwork minimizing any moisture in the ductwork. I had to spray an odor neutralizer in my vents to help control the smell when starting. I hope this helps.
