CLS63 engine oil leak :(
update: i took my car to the dealer to check if there is an oil leak,, since i got two messages within the first 2000 miles "check oil level at next refueling." The dealer came back to me today; his reply was that there is a leak somewhere in the engine and they don't know the real cause!! The car had to stay at the dealer 
Any idea on how serious this problem is?? Thanks in advance.

Well an oil leak is the easiest thing to find. Follow the oil back to where it is coming out of the engine. I bet they simply do not know why the car keeps giving that message. Likely the car either burned a qt of oil during break in (so it wa 1 qt low) or the oil level sensor is broken. The new quad cam motors do tend to burn a little oil during the first few thousand miles so thats not something out of the norm. I just got a new E350 daily driver and it smoked upon start up last night but the M272 engine is known to do that for 2k miles or so until all the valves and seals are "seated."
Unless you saw oil under the car it likely is not dripping. To lose a while qt of oil and not see any sign of a leak on your garage floor is very rare.

Thanks alot for the info. The Service Advisor called me today and said that there isn't any leak! i really donno whats the deal, yesterday there was a leak and today there isnt...he said like you said that the engine needs to be broken in at least 5000 miles and that its normal for such a car to consume more oil for the valves and seal to be satisfied. He also recommended me to drive more aggressively!!!
