Did a search and did not come up with anything. I am fast approaching 50,000 miles. At 50,000 miles Mercedes recommends changing the engine air filters: there are two filters. (these filters are in addition to the cabin filters) Did a youtube search. All the videos are for older V6's or the 4. I did not find anything for my engine, 276 which is the V6 BiTurbo- V6

Has anyone changed these filters?

• Is it relatively easy like the cabin filter in the engine bay or difficult like the cabin filter under the dash?
• Part number
• Cost

If it is relatively easy, I would like to do it myself.


Many thanks!

It is super easy, I change it every 3 years on my W205 C 43 (due to constructions here) with the same exact M276 engine.

You remove the engine cover and you will see two air boxes on either side, you unscrew (the screws are theoretically locked in place and won't fall out but I wouldn't lift it up just rotate it, since i did make a mistake and one of the screws did dislodge and fell in the engine bay (that was fun to get out : ), you may disconnect the sensors connected but it is optional.

Part number is A 276 094 05 04 and you need two for both sides.

I forgot to mention the tool needed, a T20.

Seriously?

I'm sure there are tutorials on how to search. Just search for them.

Also, just because your specific car does not show up in search results does not mean other results are no good. The E450 uses the same M276.8XX engine as -400, -43AMG, and other -450 vehicles.

Does everyone really let their engine air filters go 50,000 miles before servicing them? I pull mine out every 5K miles at oil change intervals and vacuum the debris from their intake surfaces, then replace them at 20,000 miles -- about $70 for the set and 20 minutes of time. Even cabin filter service intervals are more frequent than 50,000 miles.

Yes:

FYI, cabin filters are every 20K miles. Engine air filter every 50K miles. If dirty conditions, sooner. When I did my cabin filters after 20K miles, they were basically "clean" and didn't need to be done. I will now change them at 30K intervals.

Thanks for your post.

I had found them as well.

However, and perhaps you are not aware, those videos show the center plastic cover simply popping off. On my 2019 E450, it is far more complicated: you have to remove the air tubes as well which then gives you access to the boxes which house the air filters. However, they are in the rear of the engine compartment. Before I started I wanted to know how difficult it was: easy like the cabin filter in the engine or difficult like the cabin filter under the dashboard.

W205C43PFL was kind enough to reply that it is relatively easy and also a T10 wrench is needed where the video mention a T20.

The Frame filter equivalent is part CA11861, $16.79 for 2 on Amazon:

Sorry about that, I realized I also mentioned T20, I should had checked my tool properly before typing my answer.

Thanks for the correction!

FOLLOW UP:

Here are the steps that I used: total time about 20 minutes, 10 minutes per filter: degree of difficulty * (easiest):

1. Open hood and remove the center rubber air piece from the front bracket leaving the rubber air piece attached to the large (cosmetic) cover.
2. Remove the large cosmetic center cover. It will pop off. It is attached by plastic gromets.
3. This will leave exposed the two compartments where the air filters are.
4. Do not remove the two air ducts from the front bracket to the compartments containing the air filters.
5. There are four (4) screws that hold down the top of the compartment. Use a T20 screwdriver to loosen the screws. The screws are designed not to fall out. Do not remove the screws.
6. After the 4 screws are loosened gently lift the top off by pulling forward, there are two latches in the rear. After the latches are free, gently move the top to the center. By doing this you will not have to remove the air sensors.
7. Remove the old filter, clean out any debris and install new filter. Make sure the filter and the handle are seated. If the new filter is not properly seated it will not be possible to tighten down the top.
8. Put the top back on by first inserting the rear tabs and then tighten down with the four screws.
9. Make sure both air ducts are firmly in place directly in front of the air filter compartment.
10. Reinstall the center cosmetic cover. This will require slight tapping to make sure all gromets are firmly in place.
11. Reattach center front rubber air tube (it remained on the center cover) to the front bracket
12. Double check to make sure center cover, left and right air ducts are firmly in place.

The removal and replacement of one filter took less time than writing this post. The second filter took less than 10 minutes.

FWIW, my filters after 50,000 miles were pretty clean and there was no debris in the filter compartment.

Hope this will help anyone else wanting to replace their engine air filters.

You're most welcome and great job, I am glad parts arrived so quickly too. Good for you on DIYing it, I am all for DIYing : )
