Get out your manual and familiarize yourself with the menu system. You can access the computer system and go in and do a reset while sitting in the drivers seat... but it is always better to understand WHY you have a warning. Your best bet is to take it to an authorized Mercedes dealership and have them look at the fault.

try disconecting negative battery terminal for a few seconds

Auto Zone has them for under a hundred but remeber the rule you get what you pay for there are a number of different models get a mid priced one.

that appears to be a camshaft position sensor performance code. you can start by checking to see if the sensor is working properly, re-check and make sure that the harness is ok by checking the resistance through the harness if all looks well there make sure the computer has the latest software on it by having it scanned at your local dealer. also you can check the reluctor wheel on the camshaft for damage or debris in the way of the sensor.

hope this helps!
