Hjbeik4e!

I have a 2016 C300 4Matic and have been having some issues with sputtering/stuttering when I first start driving my vehicle. My local garage could not identify the issues I was having from the diagnostics they ran. Here is the response they gave me:

"Fault stored for CKP sensor. Technical Service Bulletin out for certain fault, which requires Mercedes to submit vehicle data to Mercedes Genius. Advise customer to take vehicle to dealership for diagnostics."

Any ideas what I might be running into when I take this into a Mercedes service shop?
