2025 Mercedes GLC300 - Changing cabin and dust filters
I have a 2025 GLC300 coupe. I'm going to change both the cabin and dust filters. From what I can tell, the correct Mercedes part numbers are:
  • Primary Cabin Filter (Interior): Part Number 254-830-15-02. This is the main activated carbon filter located inside the cabin, behind the glovebox.
  • Dust Filter (Exterior): Part Number 254-830-14-02. This is the pre-filter located under the hood at the fresh air intake.

Anyone done this themselves? I'm sure I can handle the replacement. My questions:

1) Are these the correct MB part numbers?
2) Are there any acceptable aftermarket alternatives? Perhaps MANN-FILTER? From what I can tell - the answer is no.

Thanks in advance for the help.

Shop the online suppliers such as fcpeuro, autohausaz, pelicanparts, etc. Genuine MB filters are usually rebranded Mann filters, or some other brand.

I actually used that site to begin with. But I'm pretty sure that I'm getting wrong part numbers at that site. I'll probably just call the the local dealer to verify parts. Thank for the help though.

I tried each of those last night. They either are giving me no options or giving me aftermarket options that are probably incorrect for my vehicle (frequently giving me part numbers that work with the GLC300 but only for 2022 or earlier).

I may just have to buy the MB parts this time. Thanks.

Have you pulled the old filters yet? Mine ('19 G550) were labeled with MB and Mann p/n's.

I haven't pulled the parts yet as I didn't have replacement filters. But good idea. Thanks for the help!
