4MATIC on W212 (E350) - internal transfer case?
I know the E350 uses the 7G Tronic or 7G Tronic Plus in the W212 series. My question is....is the 4MATIC system the same as the C/GLK where the transfer case is internal to the transmission? Or does the bigger and more expensive W212 get a separate transfer case - eliminating the need to replace entire 7G unit when transfer case goes bad like in W204?
Anyone confirm for me?
Thanks!
On all MB passengers cars and the GLK, the transfer case is integrated with the 7G+ transmission (reference: MBUSA website & Motor Trend, March 2012: 'Mercedes 4Matic Wintertime Experience'). Torque is permanently spilt F/R 45/55%.

Do you know - are E Class owners experiencing transfer case failures at the same rate C Class owners are? I would guess so if it's the same transmission/drive train.
So far in W212 forum land no failures reported.
Check the W211 guys and see how the older ones are holding up.
4MATIC W204s from 2008 until 7G PLUS (2013 for C300 in U.S.) have transfer case failures quite a bit. Since E Class doesn't, makes me think the 7G on W212 4MATICS must somehow be different. But I have no proof or documentation...just a guess.
Apparently most W211 with 4MATIC were actually 5 speed units? Those have separate transfer cases as opposed to internal transfer cases on 7 speeds.
Thanks again.

FYI, RWD W212 are not available in Canada, only 4Matic versions.
After some further research on this forum, 3 examples of transfer case failure in 2010 GLK and 2 examples in C Class have been mentioned; zero E Class.

. Gonna have a hefty bill after this but at least I’ll get the trans flushed at same time. I came from an Audi s4 daily and knew I made a mistake getting into a Benz. Bought this car to be the boring reliable car that I just gas oil changes and go during the off time away from the turbo. I was wrong, last Benz I buy for sure. Sad to see a car like this have such issues so soon.
I would not go so far as to say it is a common issue. Though i will say if you have a trans/t-case issue it is likely this.
Its been a while but i want to say the rebuilt trans from MB were in the 3700 range. Plus labor.
Personally, i am confident in the reliability of MB (i chose a benz for my "daily"). We see our MB owners mostly just for regular maintenance. VW/Audi are around a little more. We get to know our BMW drivers very well....
