Replace your air filters! I show you how I replaced my cabin air filters for a C-Class Mercedes Benz w203. This car has Auto Climate Control (ACC Option 581) so there are a total of 3 filters: 1 in the engine bay, 2 in the passenger footwell.
What's needed:
- T20 Torx Screwdriver
- Cabin Filter (203-830-09-18-10)
* Engine Bay
* I used Mann Filter CUK 3461
- Cabin Filter Charcoal Activated (203-830-12-00)
* Passenger Footwell
* I used Mann Filter CUK 20 000-02
