Open the hood up and look right above the battery. There should be a black cover there. At the top of the black cover there should be 3 black clips. Undo the clips and pull the black cover out. Look underneath the black cover and you should see the cabin filter. When putting the cabin filter back in, put the black flaps in first and then adjust the 3 clips to match it's counterpart. Now all you have to is reconnect the 3 clips you undid in the beginning. I know most of the Mercedes Car's have their cabin filter underneath the glove compartment, but it is not the same for this model. My uncle has the same model and year as you and I just changed the cabin filter on his car. Changing the filter shouldn't take you more than 8-10 mins. Hope I helped.
If its the same as the C240...The cabin air filter is located over the battery
My data is showing two locations for the cabin filter on the C240 MY 2004 RHD & LHD behind the glove box & below the windscreen on the passenger side.

You will need to remove the black plastic that houses the filter. Your local Auto Zone can probably rent you a removal kit.

The fuel filter on a 2002 Mercedes C240 is located on the driver's side just inside the wheel well. Not in the wheel well, but just beyond it. If you have the car on a lift, you can't miss it. It's fairly large in diameter and there are 3 hoses going to it. You will have to replace the clamps on it because they are the type you have to break in order to change it.
It is mounted on the upper front of the engine. It is a canister type.
Every 5,000 miles.
