Sincerely, Gregory Gunther Department Manager, Vehicle Compliance & Analysis Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance and Analysis Service Campaign Launch Notification February 13, 2023 Campaign No. : Campaign Desc. : Perform SCN Coding for SCR and VGS 2022020024 22P5494204 This is to notify you of an Emission Service Campaign launch to update the SCN coding for SCR and VGS on 133 Model Year (“MY”) 2012-2016 E-Class, GL-Class, GLE-Class, GLK-Class, and ML-Class (166, 204, 212 platforms) vehicles. The vehicles will be visible and flagged in VMI as “OPEN” on February 14, 2023. Background Issue Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2012-2016 E-Class, GL-Class, GLE-Class, GLK-Class, and ML-Class (166, 204, 212 platforms) vehicles, the coding of the control units for selective catalytic reduction (SCR) and fully integrated transmission control (VGS) do not correspond to the specifications as part of the “BlueTEC update” diesel field measure. This could result in the CAL ID (Calibration ID) not being read out from the vehicle and re-documented in the relevant systems. This situation does not have any additional technical implications for the vehicle. What We’re Doing MBUSA will conduct an Emission Service Campaign in which an authorized Mercedes-Benz dealer will update the SCN coding for SCR and VGS on the affected vehicles. Parts Parts are not required for this campaign since the remedy is software based Vehicles Affected Vehicle Model Year(s) 2012-2016 Vehicle Model E-Class, GL-Class, GLE-Class, GLK-Class, ML-Class Vehicle Population Total Campaign Population 133 While we regret any inconvenience this may cause, MBUSA is determined to maintain a high level of vehicle quality and customer satisfaction. Approximately two weeks after the posting of this NCU, a letter will be sent to owners notifying them of this emission service campaign.
