BMW 328i xDrive overheating issue related to catalytic converter and AC sensor on BMW 328i xDrive

Some BMW 328i xDrive owners report experiencing overheating issues potentially related to the catalytic converter and AC sensor. These owners have noted that a clogged or overheating catalytic converter can lead to limited performance, unusual exhaust odors, poor fuel economy, and the illumination of the engine check light. Additionally, while the AC sensor may not directly cause overheating, its proper functioning is vital to prevent extra strain on the engine. Other contributing factors, such as a faulty thermostat or trapped air in the cooling system, may also lead to overheating. To diagnose the problem, some owners recommend using a BMW-specific diagnostic tool to check for fault codes related to the water pump or other components, and inspecting the catalytic converter for blockages if it is suspected to be the cause of the overheating.
