Mercedes-Benz AG (â??MBAGâ??), the manufacturer of Mercedes-Benz, has determined
that on certain MY 2019-2020 CLA-Class, A-Class, and GLB-Class (118, 177, and
247 platform) vehicles, the transmission control unit software may not correspond
to current product specifications. It is possible that the vehicle may switch to
coasting mode during deceleration or rolling when engaged in drive mode â??Eâ??. In
drive mode â??Eâ??, coasting operation is displayed in the instrument cluster as â??Dâ?? and
may be green instead of white. When exiting coasting mode, the â??Nâ?? drive mode
instead of â??Dâ?? may be activated. The current drive mode will be displayed in the
instrument cluster.
What Weâ??re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will
update the transmission control unit software.
