I was really surprised with this warning message coming out of the dash 4 days after my Service A at the dealer. I drove in for a quick check and they confirmed that oil was overfilled on last week's service. I thought more oil is better and have no idea that MB keep track on oil level this way. Is this normal?

This is a new dealer I am trying who has a better service record from many referrals and I never had such issue with my previous dealer over the 4+ years. I just want to find out it this is the truth or some B.S. that they are giving me.

Thanks ahead,

It may will be what you said is the root cause. But i wonder if there is something is leaking into the Engine casuing the oil level to rise !! Have him drain all oil and replace it again. if it happens again, then u have an issue with engine seals leakong antifreez into the engine mixing water with oil !!!

You have a lot to learn about motors, then.

If oil level is high enough, it can contact the spinning crankshaft, at which point it will be whipped into a foam that can't protect anything.

I had my oil changed at a local garage. He put 9 quarts in instead of 8.5 and I received the overfill message. I bought a cheap syphon tube at pep boys and syphoned out about a cup of oil from the dipstick and that made the level normal. Drove 10k miles without having to add/remove any oil then changed it myself the next time. 8.5 qts of mobil 1 0W40

do NOT continue to drive with overfill oil. unless you know for sure how much
the overage, serious damage can result...not just a foamy thing. call your
dealer and have them fix immediately.

I returned back to the dealer immedaitely to drain the excess and problem never showed up for a week already. Looks like problem solved and very likley the dealer fault in overfill at the beginning since I have never seen such problem with previous services at another place. Thanks for the replies.
