Has anyone changed their transfer case fluid on here? If so, can anyone give input as to what the color/smell of the fluid was when your fluid was removed?
I did mine today on my 4Matic and the fluid wasn’t completely black, but it was not the gold color that the new oil looked like. Not even close to be fair.
I’ve changed my transfer case fluid about 4 times now, and every time it comes out the same color. Cars running like new (talking about the drive train in this instance). No problems with shifting or any grinding that I can feel or hear.
I’ve changed my transmission, front differential/rear differential, and transfer case fluid every 40,000 miles. Front and rear differential fluid look new every time I service it. Transfer case as mentioned looks black. Is this normal? I would expect that the transfer case have clearer fluid than the transmission or differentials because it shouldn’t be working as hard as the diffs or tranny.
I had the automatic transmission fluid/service done and the rear differential fluid changed when the car (E400) was six years old. However, I didn't see anything in the maintenance requirements regarding changing the transfer case fluid at 40k miles, which I'm nearing. Where did you see that about changing the transfer case fluid?

I don't believe there is a "set time" to change the transfer case fluid for the W213. I don't see it in my mercedes car manual either. But when you look at some mercedes dealer sites, they say to change the tranny fluid and filter: https://www.mercedesbenzoftyler.com/...-benz-e-class/
What I can assume is that the transfer case and diff fluids should also be changed every 60,000-100,000 miles (probably depending on driving habit and weather conditions). If you look at some videos online of MB service centers, they'll say they don't have service intervals for rear and front diffs (including the transfer case). https://www.facebook.com/watch/?v=1219402620092882
The diffs and transfer cases do have fill and drain screws. So it's a "why not" type of deal. If you look at my picture you can see the fluid is pretty black. I do push my car a lot and do illegal amounts of speed especially on the autobahn and through other countries. Heat and warm weather also don't help. So i'd rather be proactive and do the service my self every 40,000 miles than have to buy a new transfer case or rear/front diff for thousands of dollars.
I would do the transfer case service my self if I were you. Super easy to do.

Did the rear dif a week ago and the only issue was that the "Book" called for 900ml and it took around 1,200 ml. That was Easy.!
Not a problem, but now I need to go and buy more oil to do the Front Dif. That is supposed to be around 1 L
Stopped at Mercedes to see about the "special;" 75W85. Even had it in my hand till he told me it was $124.00 for a L. Yikes.
Back to Mobil 1, 75W90.
Plan is to do the Transfer Case (next week) at the same time. Have 2 L of the Blue ATF and a spare plug with washers.
Front differential in the W212 and W213 is 0.55l. Front differential is so small I dont think a liter would even fit.
I have a W204 and in the back of my Operators Manual in the glove box it says 1.1l for front and rear differentials. I believe the 1.1l for the front is an error since the MB manual says 0.55l. When I replaced the front differential fluid around 0.6l came out so I put the same amount back in. I pumped the new fluid thru the drain plug since there is no fill plug and the manual only has info on filling while the passenger cv axle is removed. I rather a little more gear oil in there instead of too little oil, want to make sure the oil is high enough to lubricate the two oil seals where the cv axles go into the differential.
For the W204 two quarts of oil is plenty to do front and rear differentials, should be similar for the W212 and W213.
W204 transfer case shares its fluid with the transmission so i cant answer the question above on if the W213 transfer case oil should look dark when changing. I want to say no it shouldnt, and dark color means the oil is breaking down but I really dont know.
Looking thru the MB Bevo it looks like the W213 transfer case can use the 236.15 or the 236.17. I'm assuming the 236.17 is being used since its a gold color, not blue like the 236.15. Wonder if you can switch to the 235.15 blue fluid and see how it looks afterwards.
W204 uses the 235.7 spec oil for differentials. I use the Febi 75W85 which meets the spec.

Isnt the transfer case part of the transmission in the W212? Thought they have the 722.9 transmissions.
The 722.9 transfer case shares its fluid with the transmission. The fluid goes thru the oil cooler into the transfer case then into the transmission.
Website is for diesel vehicles which use the same fluids with gas. Bought other parts there like transmission filter and gaskets, torque converter drain plug, sealing rings, undertray screws and clips.
They are in MA and offer free pickup at the warehouse which is convenient if you are close.
