Mercedes smell air conditioning finally solved
After two smelly ML’s (2012, 2015) I went on the hunt with trial and error.
This WILL work on a ML or GLE. Should on others.
First and foremost, when going through a car wash always put your air on recirc.
Now, how to fix.
Get two cans of Kool-It.
spray one can up the drain line. It is hard to get to on a ML, but it is worth the hunt.
spray the second can down the right center vent. Push the hose as far down as you can.
let it sit for 5-10 mins. The. Drive your car for 10 mins with air on Max.
now the secret part.
Purchase these air filters off Amazon and the smell will never return.
