Mercedes-Benz C250 dashboard lights on and radio in theft mode possibly related to outside temperature sensor on Mercedes-Benz C250

Some Mercedes-Benz C250 owners report experiencing dashboard lights illuminating, including ABS/ESP indicators, which may suggest issues with inoperable systems such as the speed limiter and cruise control. Additionally, some owners find that their radio enters theft mode, possibly triggered by a power interruption or battery change, which can often be resolved by entering the radio code. Furthermore, problems with the outside temperature sensor may affect various vehicle functions, including the radio and other electronic systems. To address these issues, it is recommended that owners check for fault codes to identify specific problems, inspect the outside temperature sensor for proper function, and consult a qualified mechanic or Mercedes-Benz service center if the issues persist.
