Awd donuts in an e550
Hi everyone,
as the snow continues to fall here in New England the temptation to let it rip grows. I understand I could be applying extra wear to the center diff of 4m e550, but could anything else be extremely worn? I take care of her as if it’s my child, oil changes every 4k miles, just changed the rear diff oil at 67k miles, etc. any help would be appreciated!

It spins under acceleration. The rear will kick out no problem. It moves right out in any snow, but crank the wheel and give it gas and whooopie!

We don't get enough snow to "play" like that 
But with 4 people in ours from a stop doing a left turn in standing water and pouring rain. It was a yawn... Nothing but very fast acceleration - it might as well have been dry... ContiProContac tires.
Let's hear about the snow, and I wouldn't worry a bit on the center diff - snow isn't going to bother it. What I did, would work it much harder, not to mention those that take theirs to the drags and do power brake launches...

So...
Given that the ESP will no doubt raise a fuss and turn down the throttle one is pushing while trying to do donuts, you'll have to turn ESP off (or at least turn it down). Easily done on a 211 via the button on the center console, fairly easily done on a 212 in the IC menu. On the 211 one can enter "Dyno Mode" where ALL the nanny stuff is turned off and the car will do exactly what you want it to until you start hitting telephone poles. Is there a Dyno mode on the 212? If so, how is it accessed?

See post #4 in this thread. 4wd is split 45/55r in the 550. It’s 33/67 in the E63.

um, its in the transfer case, not the differentials. change one differential ratio and snap axles as your wheels want to spin at different speeds.
I dunno re donuts, I'd rather do my hooning in something a lot more disposable. I used to power slide around muddy lots in ratty old cars I didn't much care about. learned to control FWD torque steer with a 1984 VW Rabbit in the mud and snow...

Installing a 63S LSD Rear diff would be a bad idea then?
i dont need lsd in the rear but i want it lol

both front and rear diffs need to be the same final drive ratio, unless you are running staggered tire sizes with different outer diameters, in which case the ratio of the ratios need to match the ratio of those outer diameters.
as far as LSD goes, ESP does the same thing via the wheel brakes, transparently... any wheel starts to spin excessively, ESP engages that wheel brake to slow that wheel down which naturally redirects the torque to the other wheels... this is much smoother than the traditional LSD which goes from full slip to full lock in a single clunk and typically will only engage at fairly low speeds (my 92 Volvo 740 turbo's Dana locking rear end would only engage at speeds below 35 MPH, causing a clunk you felt in the whole chassis if you were on a variable traction surface... thankfully you had to push it pretty hard to get there).

Mercedes has been playing with traction control for awhile. I come from owning W124's, which were the E class from 1986-1995... I have a 1990 300E 2.6, 1993 300CE Cabriolet, and a 1994 E320 Wagon.
anyways... while none of mine have this, Mercedes tried two traction control systems out on W124 back in the late 80s/early 90s. the first one involved inboard brakes on each side of the rear differential, and a complex hydraulic system, this was called ASD. a later version, ASR, used the ABS brakes with a drive-by-wire throttle, and was pretty much a predecessor of what is in the W212 ESP system. There was a W124 4Matic too, but it was nightmare complicated, and many folks describe it as a 'beta test' for AWD. But the 124 4matic was stuck back in the first generation until the W210 fixed/enhanced the AWD system. and its been good ever since.

A buddy and I gave it a shot and well....... there was something definitely left to be desired. The snow tires were doing their job well so I found it difficult to break the rear loose. Now that I got it out of my system I won’t be doing this again but if I was, I’d put the car into dyno mode rather than disabling esp as that would turn everything off

yeah, dyno mode mostly disables all the nannies...mostly...definitely more than just turning ESP off. I have to disable ESP in the cluster just to get the car to keep moving under full acceleration from a stop. If I don't disable, the car will flat out fall on it's face in about 20-25 feet, due to all the tires spinning and ESP cutting EVERYTHING and slamming on the brakes...that is embarrassing. As long as I'm going straight, with the ESP turned off, It'll spin the fronts about 15-20 feet and the rears for about 40-45 feet, but doesn't cut anything, except AWESOME 60' times!!!

Damn straight! Love it! We had 10" over the weekend here and I love this time of year. My son and his family were skiing at Big Bear in CA a week ago and they had 3 feet! I love snow.

I found it pretty difficult to lose the rear even on gradual turns rolling into throttle. The system kept the car fairly straight....pretty impressive. Even on a large radius turn rolling In to it. Felt the rear start to walk out and the car just brought it back. Tapping the throttle in an open lot going into a turn....all bets off. Next introduction to throttle and it straightens out.
