Campaign No. 2021060017, August 2021

TO: ALL MERCEDES-BENZ CENTERS

SUBJECT

Model GLE-Class, S-Class (166, 222 platform) vehicles

Model year 2015-2017

Update Power Electronics Control Unit Software

Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year ("MY") 2015-2017 GLE-Class and S-Class (166 and 222 platform) vehicles, the software of the power electronics control unit does not meet the current vehicle specifications and thus the possibility exists that the temperature sensor may fail and a MIL and a fault message "malfunction" will appear in the instrument cluster as a result. An authorized Mercedes-Benz dealer will update the software for the power electronics control unit.

Prior to performing this Campaign:

VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly.
Please review the entire Campaign bulletin and follow the repair procedure exactly as described.

Approximately 721 vehicles are affected.

Order No. P-SC-2021060017
