Musty or foul smelling Air Vents?

Well, you SHOULD replace the Cabin Filter each "B" Service, or around 10,000 Miles.

Again, very quick and easy..... so no excuse!

Thats too cool, Your photo write ups are excellent. I was wondering where the cabin filter was and how to change it. Thank You for taking the time to do these write ups.

Definitely reach up in the ducting for the filter as far as you can to clean out any debris. Also, if you are ordering parts online you can usually get charcoal impregnated filters for about the same cost as plain. Charcoal helps minimize the foul smells, at least when the filter is somewhat new.

Yes, Filters DO VARY SIGNIFICANTLY.

I know everybody and their brother loves the AutohausAZ.com for their cheap prices.

BUT... you often get what you pay for.

I was extremely disappointed with the quality of this cabin filter. Literally, their filter had ONE QUARTER of the "mass" as the MB filter.

I had the exact same experience with a W140 Pollen filter....

I think I have learned my lesson.... Stick with MB or MB supplier. Since the application is not particularly mission critical, I just used the thing.

Fuel and Oil filters?? They are FINE. They are the EXACT model as the OEM MB (Knecht und Hengst), but without the "Star".

I just replaced the cabin air filter on a 99 C230 and used the carbon impregnated filter made by bosch. Strange enough the filter has an arrow indicating the air flow direction, but unfortunately there is only one way the filter goes in and fits correctly. That way the arrow points to the wrong direction. Not having any other way to fit it then I left it that way, but it seems that Bosch goofed up on the placement of the charcoal side on the filter. Oh well they have caused me more problems with MAF, CPS, etc. I will try one of the OEM products next time. Hopefully the carbon will still do some odor reduction.

Excellent pixs on how to replace the CAF. I attempted to follow instructions on how to do it on my 2006 SLK-280 but it appears that my SLK does not have a CAF under the glove compartment. I took it apart and there was no white plastic brackets, only a big white plastic cover that extend almost as large as the black cover. Any ideas?

Apart from the reduction in odours and dust in replacing the cabin filter, it's amazing how much better increased the airflow is. My air conditioning feels so much crisper.

I highly recommend you other forum members do this on your cars; you'll be pleasantly surprised with the instant results.
