a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

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?

1) Turn the key to position #1 and make sure the menu in the instrument cluster is on the total mileage and trip mileage screen.
2) Press the 'accept call' button and hold it. Then press the 'ok' button, this will take you to another menu screen.
3) Scroll around to find 'assyst plus', hit 'ok'.
4) Find the 'full service' option and hit ok
5) Confirm service with the ok button, it will then say 'service confirmed'.
6) Use the back button to scroll back out.
Hope this helps. Thanks for using FixYa.

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.
