★ Top Answer
The thermostat in a BMW, known as code 140, is located within the thermostat housing along the lower coolant line. This component is responsible for monitoring the coolant temperature as it flows through the line, providing crucial information about the engine's operating temperature. A malfunctioning thermostat can result in the engine overheating, leading to potential damage such as warping or cracking the head gasket, which could be a costly repair in the future. If the check engine light indicates an issue with the thermostat, it is essential to address it promptly to avoid further damage. Replacing the thermostat typically costs around $200, so it is advisable not to delay in getting it fixed.
