2013 GLK250BT USA Air Filters

Thanks!




Has anyone replaced the black intake hoses? I find it's hard to take off the top without breaking the hoses. It doesn't seem like particularly wonderful material. I was wondering if some flex aluminum wouldn't be better?
Very easy and straight forward. You wil need a T-25 bit and a skinny extension and possibly a few cable ties.
Remove the 6 screws around the perimeter of the air box and there is also one in the middle of the air box. I disconnected the two cam-lock electrical connectors on the computer on top of the air box, but this may not be necessary. I just thought it would be easier. I also cut a few of the cable ties securing the wiring harnesses to get some slack. Also, this may not be necessary.
Pitfalls: If you decide to disconnect the gray and red cam-lock electrical connectors-make sure you press the safety catch on each one. They should easily unlock, as long as you press the safety. Also, the passenger-side air box screw nearest to the firewall is a bit difficult to get to. That's where the skinny extension comes in handy.
Lift the top of the air box up and force the old filter off the intake snorkel. Pop the new one in there. Line up the air box and tighten screws without pinching any wires. Reconnect electrical harnesses, as applicable. Strap harnesses back down and test run the engine.
Not sure what the dealership would charge, but $38 and about 30 minutes and you can save yourself some cash!

I can confirm that GLK250BT (diesel 651 engine Std for USA) has ONE AIR INTAKE FILTER. Just replaced ONE by MB DEALER @ OTTAWA Canada.
(yip am a US customer on a long road trip)
The MB Dealer was kind enough to let me wonder around in his workshop as they (did some 'pre-due-service' to my GLK) changed OIL + Intake Filter. There is only ONE intake in Diesel engine and even I can see the other intake is blocked off just above the radiator! I did want to change the 'cabin filter' but when the Tech took those out - he recommended to keep it - and change after "spring pollon ' count has reduced!.
Side note = <<<<removed>>>
Hope this helps
Cheers

I wanted the OIL CHANGE + INTAKE Filter = mostly as to rid of the WINTER salts, rid of bugs etc as we drove from Boston to PEI and all over NS etc. So far we done 8000KM approx.( sorry I switched to KMS in Canada)...
Hope this helps

It's " MB approval 228.31" from the Shell website, but not for GLK diesel. I do not know how big the problem is with that.
All I see is that 229.51 is approved by Mercedes for GLK250.

>>so sorry had wrong links >>> should been the SHELL RIMULA OILs (( not the other one))) my bad!
Mmmmm...........Note> read this part of post...
and when I asked for SHELL (( rather than Mobil1 which I generally prefer to use on our other diesel cars - Audi's)) The Tech Comments were - " they generally prefer to use it on Sprinter trucks mainly in WINTER... but its ok to use anytime in Canada"....
So since it comes recommended by BIG RIGS (where their engines are far more prone to heavier stresses - thus need for better protections etc) WHO AM I TO ARGUE !!! > am ok to use it and would probably change it when am due for my FIRST NORMAL SERVICE (15K km in Canada10K miles in USA) ....
Also - Asked the same tech about the "oil vacuumed out" which is what another poster has had asked for. This dealer does not practice that - the tech said he just flushes out the oil via the bottom and then use their 'oil flushing system' if needed - (((which he showed me - seems like a very low pressure closed loop oil pump system for cleaning any used oil in cars /suvs)). He said that wasn't needed in my car yet - as we have only 8k KMs on it and wasn't really in any 'dirt' yet .............
hope this is helpful... but I am sorry I was not going to post things on THIS THREAD about :oils : and would like to leave it for OP's topic = filters ( just wanted to let everyone know - GLK250 = one inlet = one intake filter
sorry - am removing all mention of GLK OILS here .....!
cheers

You do have to "push" the cover down to get the screws started. There is a "spring" mechanism to the air box so that it seals the air filter so that the dirty air on the exterior of the filter cannot bypass the filter into the intake snorkel.
Hope this helps.
