You must be a service advisor for mercedes, you sound just like them!!! IDGAF who drives what, where or how they interpret the smell, the fact of the matter is that this smell is a result of a poorly designed hvac system!!!!

I’m having the same problem since the day I drove off the lot. It’s been in the shop three times and I still have the same horrible smell. It’s beyond ridiculous I am going to hire an attorney to get out of this lemon. No water drips out while the AC is on I think it is collecting somewhere and its creating mold. Someone needs to bring this to light I'm getting sick head aches everyday now. I have never had this problem with any other car I've owned Mercedes-Benz for 20 years and this has never happened before.
We're you able to get out of this problem? Currently going through same!!

Newer had this, Temp control aways in Auto, and newer in recirculation. Leaving in sunny Seattle, WA.
Dust filter changes every 10K and cabin filters every 15K.
PS. My wife's car, not MB had this once, had to turn fan full speed and used Lysol cleaner run and sprayed for about 30 mins.
Replaced cabin filter, so far so good been a year now.
Agreed, MB had design problem, but looks like its climate dependent otherwise we would see so many claims and recall.

So, while my service history said the dealership performed the LI83.30-P-059119, the smell still persists because that bulletin's theory is "Oxidation products of the cavity preservation can enter the interior compartment via the air conditioning". We all know that IS NOT the case....it's the mold/mildew forming on the evaporator.
Therefore, I just stopped into the dealership to inquite about them performing service bulletin LI00.00-P-066047 (which includes re-programing the climate fan to come on after 3 min instead of 1 hr), and they want to charge me $660.00...just to update the climate control software.
That's outrageous!
I even have an extended warranty.
It's like Mercedes actually WANTS to lose a customer for life.

That's ridiculous. If there's a service bulletin for it, how can they justify charging you for it?

To be honest it could just simply be mold. Back when I was in college I had a similar issue with my Honda Accord. I took it to the dealership and they simply put my windows down, cranked the AC and the fan on full blast and sprayed lysol from the outside near the wipers where the air goes into the AC unit. It surprisingly got rid of the smell. With that said, try doing the same with your car. I still do it to my other cars every now and then. Just remember to keep ur windows down for a maybe 10 minutes and have the AC and fan on full blast after you spray the lysol that way the chemical smell leaves ur ventilation system and ur cabin. Hope this helps, keep us posted.

It absolutely IS mold…..there’s no question about it. The service bulletins that have them take apart your whole interior and plug-up and seal various holes in the body, do absolutely nothing. It’s simply mold growth on the evaporator.
And I highly recommend removing all the filters, before spraying any cleaner into the system.
Has anyone had the dealership re-program their climate fan (to turn on after 3min in lieu of the default 1hr)? Does anyone know how much they should charge for that service?

So, after reading the extended Certified Pre-owned Limited Warranty...
It states the following is covered under electrical items:
"....sending units,sensors,switches,fuse boxes,relay modules,control modules,transmitters,instrument panel,gauges,rheostats,potentiometers,blower motor series...."
Therefore, wouldn't the procedure of "Updating the latest software for the air conditioning control unit" (from bulletin LI00.00-P-066047), including changing the values for the drying time of the evaporator be covered under the "control modules" part of the warranty?
And under the Climate Control section, it states: "All electrical components noted above,as well as the A/C compressor and clutch,receiver/drier bottle,refrigerant hoses and connections,evaporator,expansion valve,condenser,rear vent control cables,vacuum actuators,all vacuum valves and elements,auxiliary cooling pump,cold engine lock-out switch,temperature selector wheel,servo unit,monovalve,dualvalve,switch over valve,heater core and heater housing assembly.
Unfortunately...I think I'm going to have to fight this. I guess I'll call the 1-800-367-6372 number.
