How can you improve the cabin air quality in a 300SD?
I've been driving a rental car for the past week while working on my SD, and one of the first things I noticed was the difference in cabin air quality between the two vehicles. I don't have any water leaking into the SD, so I don't think that mold is an issue. I think that there is so much dirt and dust built up in the HVAC system that I'm just getting a lot of particulate matter floating through the air. I've seen stuff at the chain auto parts stores that you spray on your evaporator, and a mechanic once told me to spray Lysol through the vent cowls. Can anyone suggest a method that has worked for them. Unfortunately these cars didn't come with a cabin filter.
BTW, the rental car was a Chevy Cruz, and other than the 6 speed automatic transmission, I was pretty impressed. I hope that Chevy's diesel version of the car does well.

Yeh I know, its called a lot of pine tree air filters hanging from the rear view mirror
I am not sure on an SD, but I know on the w123 they used untreated horsehair in the seats....when this rots it makes a lot of nasty particles and smells....I also know the same is true for a lot of the foam products they used....it breaks down after so many years and becomes air born.....I have heard of people install cabin filters on these models but its not easy....then the only true way to rid the car of the particles and smells is to find and replace the items that are breaking down....this would also include cleaning the entire HVAC system... So the easy answer in my eye....is no...

What I do on my 84 500 SEL. Just in front of the air intake is a fire wall that has a rubber seal on top of it. Pull the seal off where it passes the air intake grills. Take 3 Bounce dryer sheets and lay them over the air intake, overlapping each other, with the front edge of the sheets on top of the firewall. Push the rubber seal back on so it holds the sheets in place. The sheets act as filters and help with the smell in the car.
Is it a fix for the problem? No. Does it help some? Yes. Paul

extreme measures........
After removing the dash and center console, you can follow these steps to clean the airbox:

Make sure there are no exhaust leaks, you can have a exhaust leak and not hear it. Look for black carbon at each joint.
Track down and repair any fuel leaks, even a small one can add smell. Pull the seats then vac, spray clean the carpet. |

The interior of my 420sel is clean and smells fine....just like older leather smell. Its all about keeping everything cleaned. I wash the windows, vacuum everywhere, and treat the seats with leather conditioner regularly. Can shampoo the carpets too.

I find that smoking cigars in the car really helps you not to be able to notice all of the other smells.
