Perform Software Update to Air Conditioning Control Unit

This is to notify you of an Emission Service Campaign to perform software update to air conditioning control unit on 9,119 Model Year (“MY”) 2016 – 2021 C-Class (205 platform), E-Class (213 platform) and GLC (253 platform) vehicles. The affected vehicles will be visible and flagged in VMI as “OPEN” on June 16, 2023.

 

Issue
