Search the boards, geng77. These types of problems are also present in other MB models.
Take the car in and complain about this issue.
See this recent thread.

MDCLS, your technique is great if the car you are working on does not have a cabin air filter. On a MB, it will succeed in soaking the cabin air filter with Lysol without getting the Lysol onto the evaporator. You also have to remove the activated charcoal air filter if your car is equipped with one.
Plus, there are sensors in the AC system. Who knows if the Lysol is compatible with them?
The newer MB evaporators supposedly have an anti-fungal coating to avoid the mildew smell problem.

This is a moisture condensation problem. Get in the habit of turning off the AC a mile or so before your destination and your AC will no longer smell.
I was told to do this by a tech a long time ago, and have never had any AC odor since.

I say complain and force the dealer to fix it. The user shouldn't have to work around it..

I agree with you ricky. joec1101, on my W211, hitting the AC off button does not immediately turn off the AC compressor. It takes somewhere around 5 minutes for the compressor to turn off, so it is not as easy for me to do the "turn off the AC compressor" technique. I was under the impression that the latest MB cars have an anti-fungal coating on the evaporator and better drainage from the evaporator housing. Is this mildewy smell happening with several CLS owners, or is this a problem localized to geng77's car?

The dealer will clean your A/C system with Wynn’s treatment part #A211 30208 http://www.wynns.be/ (click on products; professional; A/C; then either image) taking about 1 ½ to 2 hours to complete. This treatment should last for at least one year. One treatment per year is covered under warranty. To reduce the possibility for this condition to reoccur, you’re asked to operate the blower at a higher speed, especially during humid conditions.

Another thing you might try that I've tried in an E500 is to turn the AC on full blast for a few minutes when you first start up the vehicle. It tends to blow out most of the offending moisture and the smell is drastically reduced, sometimes eliminated.

2006 CLS 500
Molded AC covered under warranty
2006 CLS had the spray treatment done last fall at the dealer to rid the cabin of smell. It worked for the winter, but then the molded, dead cat pee odor came back really strong this August.
Brought the car into the dealer for service, and it's been there for 2 weeks... MBZ is not only replacing the condenser with a newer "coated?" unit, but also the entire air ducting for my CLS. Expect it to be in the service bay for another week or two waiting for parts.
For what it's worth, MBZ and the local dealer have been incredible through the process, and are doing everything in their power to remedy. I'd urge anyone with the same issue to bring it in and get it fixed. A $72K car should not smell like cat pee.
We also found that the oil pump needs to be replaced, as it was making noise on start up.
