Due to the semiconductor supply, the Local Interconnect Network module in either of the exterior mirrors was switched to another controller. That one provides an imprecise voltage measurement, which the main controller interprets as a fault. For the driving cycle, the customer may lose the display in either mirror and the Lane Change Warning function and, if installed, other functions such as\- Side collision warning; Lane Change Assistant; Steering and Lane Control Assistant; Emergency Lane Assistant Hands Off 60 Assistant.

- [B121221](/bulletins/10205615.md), 2021-12-27, Service bulletin: BACK OVER PREVENTION. ???Due to an unfavorable operating point primarily in the low\-end torque range, the fuel vapor scavenging that takes place in that range may result in incorrect detection of a mixture that is too rich. As a result, an incorrect mixture adaptation value is stored.
