Question about Mercedes-Benz B-Class
With the key in position 1, hit the odometer reset button on the left on the cluster 3 times in a row. The cluster should beep once. scroll through the multifunction display with the page buttons until the display shows the onboard voltage screen. It will say something like "UB: 12.2 V" scroll threw this menu with with the up/down until you reach the "service menu" page. scroll down to "confirmation" press +, confirm full service with +. Wait till it says service confirmed. cycle the key off and then back on to position 2. Scroll to the normal service menu where it normally says how many days or miles till next service. If the service was reset correctly, it will say "service display not possible" for a few minutes while it recalculates. You must cycle the key off and back on before it will back out of the onboard diagnostic mode. If you dont back out, the esp/abs/bas lights will illuminate when the car is started

Try this, it is the procedure
for resetting the ASSIST computer on many Mercs
1...Turn Key to position No:2 in the ignition / steering lock and immediately press AND Hold the button "000.0" (the trip reset button) TWICE within the space of 1 (one) second.
2…Turn the key to position No: 0 in the ignition / steering lock. Then release the button.
3...Press AND Hold the button "000.0" (the trip reset button) and turn Key to position No:2 in the ignition / steering lock. Keep button pressed
After about 10 seconds the service indicator will reset and an acoustic signal may briefly sound
That should do it....Good Luck…...Let me know if it works?

Is the merc dealer serviced??, sometimes if you change brands of oils in synthetics >>semi synthetics you will get excess oil useage. City driving will tend to use more oil, but the merc should be able to do its 10,000k betwwen oilchanges.
Anyway, check what oil is being used in both weight example 0-60w, 5w-30 etc and by brand, check that the API oil spec meets what is required for your vehicle example API SM, SJ, SL etc.

You will need a code reader/scanner called OBD2. They are under $50. A nice one can cost $100-$3,000. Just buy one that does the job...no need for the more expensive ones. You can borrow one from some auto parts stores, like the AutoZone.
You can also pay a shop this much to do it for you, every time.
Just select erase codes, and you're done.
