4MATIC on W212 (E350) - internal transfer case?

Hello all.

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!

No W212 owners are familiar with their tranmission? Or is everyone just out driving this weekend?

4Matic transfer case

The answer to your 1st question is YES.

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%.

Thanks Derek!

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.

At what rate are C Class owners experiencing failure? What year C class?
So far in W212 forum land no failures reported.
Check the W211 guys and see how the older ones are holding up.

I have yet to read a report on any W212 forum about a failure of a transfer case.

Cool. Thanks for the replies.

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.

Your last statement is absolutely correct ! Yes, they had 5 spd transmissions, resulting in rather poor fuel economy. My previous 2008 E320BT (RWD) had a 7 speed transmission, combined with V6 diesel = much greater fuel economy than either gas engined E350 (RWD or 4Matic).

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.

When my transfer case failed it made a high pitched whine at 40 MPH and above. No vibration to speak of.

I can almost guarantee it is the center differential lock. Your problem does not exist other than when you turn and gets worse with start turns. Going straight you do not have vibration because going straight does not generate speed difference between front and rear axles, only turning does. It is poorly lubricated disk pack and MB has specific instructions now how the disks must be soaked in oil before assembly. Search internet. I have seen a YouTube video of the dusk pack repair too.

im going through this exact thing as I type. I got car with 60k on it a couple years ago. Noticed vibration in D and R only in idle and everyone said mounts. I let it go cause it really wasn’t that bad. It really started to get worse recently and I’m at 76k miles now. Noticed it’s a big issue as car gets warm to temp after a drive and in a parking lot, lock to lock and only idling into a space car shutters and makes a mechanical clunk click like a big 4x4 pick up in 4L. I instantly knew it’s more than mounts and took car straight to mercedes specialist. He said likely mounts. Calls me today and says not mounts at all, you have. Clutching system in the trans that needs to be replaced and a bad wheel bearing up front?? He said the bucking and clinking was from the Trans area I’m assuming this is the PGT (planetary gear) binding up or something of that nature. And bearing I had a feeling was going people kept telling me sounds like tires, I knew it was more than tires and was hoping it was mounts transmitting sound through to the cabin. My worst case hypothesis came true . 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.

As a tech in a mostly import shop, 4matic t-case shudder/noise has been noticed. So far only the E class cars are the ones that we have actually fixed by replacing the whole transmission assembly (7 speed). Seems the C class owners either traded it in after receiving the estimate or just kept driving the way it was. (or customer base is mostly C and E class stuff)

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....

Hello, also just purchased a 2016 E350 4matic with 60k on it a week ago. Having this same issue (my thread here: https://mbworld.org/forums/e-class-w...ml#post9170158), can't for the life of me find a part # for the planetary gear. Also, weird thing is, I get a clunk/creaking sound from both front sides as well while just stationary turning the wheel to the left or right, I don't see how this would be anything other than suspension-related? Thanks.
