200 k air filter housing removal, battery-radio issues?

hi,

i want to remove the air filter housing from my car and on the Mercedes workshop manual it says to remove the battery terminal,and I don't know if the radio will require a code afterward, is it essential to remove the battery terminal?*

Are you intending only to change the air filters? There is no need to disconnect the battery to do that.

Remember when re-fitting the housing to ensure that it is right down on its 4 mounts - otherwise you will get engine breathing problems.

You don't need a radio code with the COMAND radio. I am not sure about the other radios. Another forum poster will be able to advise about that.

+1 what Keyhole said, most manuals / SOPs instruct to disconnect the battery as a precaution. If the radio is factory installed no Pin required.

That seems to be a completely unnecessary precaution. Its almost all plastic and there is nothing close to it that is live when the key is out.

The clips that press into the rubber rings bend very easily. When I did my last oil change most of them were badly bent and the covers were not properly on. You can easily fix the clips with needle nose pliers.

Also, the metal spring/clip in the far back can come undone. Its easy to insert it properly. It should clip over the plastic tabs on the housing with some force.

The op has a CLK200k
is that a M271 ?
If so , the metal clips on M112 are not an issue ..and the rear spring clip near the intake tube is only on M272 350.

I agree , no need to disconnect the battery. Just T20 torx screws to remove.
Unless you are actually removing the entire housing ? Then probably a good idea,,,no radio codes ,,but could need reset of power windows and sunroof.

Yes Benzyle, that must be M271 so as you pointed out it's a 5 min job.
@abril , do not pull out the screws from the cover as they're tied to it - once you have them undone just lift the cover, remove the filter and clear all debris in the housing, fit in a new filter ensuring it seals properly against the intake, and replace the cover. If you haven't already / recently you ought to consider replacing the cabin / pollen filter which is clipped in a plastic tray right above the battery - not tools needed.

Thanks guys.I want to remove the air box because mice got in the engine compartment and probably chewed some wires back there and now it runs a bit rough and it shows the code p0170 fuel trim bank 1,on the manual it specifies that that step was removed(the battery disconnection)?! There is an ecu on the box,the radio was installed by the factory so i don't have to worry ,i have read about problems caused to the airbags from disconnecting batteries.

i have replaced that air filter recently, the one that i haven't changed it in a while is the filters for the cabin, so i am not using the filter function on the climate control since they are old,i should tend to them as well.

Sorry abril, on re-reading your first post I admit I misunderstood your query - I thought you were looking at filter replacement rather than the housing. In this case I'd disconnect the battery just to make sure there's no spikes when you unplug and replug wires. I've done it many times and no issues, other than having to reset the windows - which you can easily do yourself by opening each window fully, pressing the button until you hear the sensor "click", and then closing fully while pressing the button until the "click" is heard. Rinse & repeat for all windows, if it's a convertible you might need to do the same with the soft top.
