Just had my 2012 E350 in for B-Service at my local Authorized Dealer last week and been to busy to check the oil level until just now.
It worries me that the oil level is way too high on the dipstick - above where the plastic ends, going on the metal.
I feel like I should be concerned and go back, right?
As a matter of fact, when I bought the car at the same place, it had just been serviced and it was the same thing (just not as much) and I had them correct it when they corrected some other matters.
What do you guys think?

Reason: incorrect
Over filling the engine oil is not a good practice. I would go back and have your SA check it. Also make sure you check it once the engine has warmed up.
Very unlike a dealer to do something like that. Ask them how something like that could happen and let them discuss it with the tech, who may be doing this to every car he/she touches in the service bay.
You do not compensate for any oil that may be seeping through and burning by over-filling. You just add oil as necessary. My car burns no oil. Does yours?
Mine didn't really burn any for the last year / 10k miles... maybe 1/4 of defference between Max/Min on the dipstick. So shouldn't need to overfill quite so excessively...
I don't know how "over full" your pan is but if it is truly too much this is a bad thing. All that splashing causes your oil to foam up and it doesn't do its job. My point is, this really shouldn't wait until Friday. At least get a better measure for how much is in there and if it is in fact frothing over.
Having said this, it is probably not, but I wouldn't risk it, considering you can get an idea from a quick phone call to a mechanic that is not associated with whoever did this.

MB just told me yesterday that some of their cars do. Mines needed to have oil added so yes. They said it was a little low. I have a friend who has and AMG ML63 and he tells me it burns oil as well.

Thanks, but I won't have to drive all day tomorrow, so should be safe until Friday morning
over filling is as bad as under filling if not worst. its easy to drain it from the dipstick tube if you have the machine, although if you want your dealer to see it id wait till you bring the car back.
now im assuming youre measuring it correctly.
i normally check my engine oil at least 10 mins after i park the car on a leveled garage. some say an hour after, some say a couple of mins and some with a cold engine. whats the correct way to do it with our MBs?
Interesting. I just had my car serviced last week which included an oil change and today I got the "Check oil level at next refueling" when I called the dealer he said that can be trigged by either too much oil or too little.
Haven't had time to check it yet but I will tomorrow and report back.
Common problem and this is how it was explained to me: they stick a hose down the dip stick tube and suck out the used oil. If they don't put the hose in all the way, or it pulls out some on it's own, or they don't give it enough time, some oil remains. They refill the oil with a machine that puts in a measured amount according to your motor type and it gets added/mixed to the oil that wasn't removed. It could be a lot. A friend had this happen and his car started smoking from multiple locations in the motor as the oil seeped past the seals because of the added crankcase pressure. It could damage seals. Proper fix is to remove all oil and fill with correct amount.
This is unexcusable, these tech's are suppose to be professionals. Obviously they didn't even check the oil level. Call MBUSA America Coustmer Service and report this fatal error.
I prefer to check the oil when the car is cold and has been sitting for a while. Doing it this way means most of the oil will be in the pan for a accurate measure.
For the problem you have mentioned, this is why I change my own oil and try to do simple repairs myself. I trust nobody!

How did the extra oil cause added crankcase pressure? I always thought that the crankcase is vented to the engine intake for any possible "added" pressure.
Well guys the jury is in! Something was messed up. Waiting for a tow to Mercedes now. Car started smoking at 80mph and when I pulled over the oil cap was missing entirely. Looks like they didn't screw it on properly which may have been triggering my "check engine oil level on next refueling" warning.

Well damn, is that oil coming out of the side of the hood there? I hope everything turns out ok and it's a quick fix. S/B just a cap replacement if your lucky.
