Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint Customer states CEL is active in instrument cluster, may report rough running. Cause Possible ME control unit software Remedy On applicable vehicles with complaint above, check for ME software updates and update as available. Afterwards ensure that the mixture adaptations are cleared by viewing the injector performance data in the ME. Perform a sensor rotor adaptation then perform an AMG engine adaptation drive. Afterwards drive the vehicle in "C" with ECO disabled for about 50 miles. This drive needs to be on surface streets (no steady state highway driving). Afterwards let the car go to sleep, then test drive it again and QC. If the complaint is no longer present, release the car to the customer. If there is no software update available OR if the complaint reoccurs, process the car via LI07.61-P-070707.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI07.10-P-079748 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the LI07.10-P-079748 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
