My car has an ongoing problem with the hvac system. It generates a mold and mildew smell while using the ac and heat. Mercedes says they no of this issue but have no permanent fix. The smell is so bad that it is almost un-drivable. Mercedes dealerships have bulletins that denote the issue is known, but their work around only temporarily improves the smell. There is an obvious engineering issue with the hvac system that is unhealthy. There is apparently that forms around themold around the ac evaporator. Mercedes has an internal alert #tsb li83-30-p-059119.this is not a permanent fix and only improved the smell for 3-4 weeks and took over two days to implement.the smell occurs all the time when either the ac or heater is on. This started at 2200 miles and continues today (i have 17k miles now).
