Oil Temperature problem
Not sure if the senor is malfunction. The car was running for more than an hour and the oil temperature will drop from 88 to 72, 73....back to 87 sometimes 90 but it will go back to 77 or something. Does anyone have this problem ? http://www.youtube.com/watch?v=gofWSGdUBgg

You need to first start out diagnosing the problem, replace the oil sender unit or sensor. If that doen't fix the problem, it's either the gauge, or the oil pump (expensive). I would take it to an independant shop, before Mercedes, to at least save some money.
