TO: ALL MERCEDES-BENZ CENTERS

SUBJECT

Various Models

Model Year 2007-2014

Update Control Unit Software Configuration

Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that during a workshop visit of certain Model Year ("MY") 2007-2014 SLK-Class (171 platform), C-Class (204 platform), E-Class Coupe/Convertible (207 platform), CLK-Class (209 platform), SL-Class (230 platform) and G-Class (463 platform) vehicles, configurations were written into one or more control units that might not meet current production specifications. In this case, installation of incorrect software configurations could cause one or various control units to malfunction. Various system failures, such as loss of drive power, reduced exterior lighting, or loss of dynamic control functions including stability and traction control might occur, which could increase the risk of a crash and/or exhaust emissions depending on the control unit affected. An authorized Mercedes-Benz dealer will update the software configuration of the affected control units on the vehicles.

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.
