Detailed Description

Global Parts 1812259 is an engine management sensor used to monitor exhaust temperature in diesel applications. The sensor’s accurate signal helps the ECM manage emissions-related strategies and supports proper operation of fuel, exhaust, timing, and cooling systems. Its 2-terminal blade configuration, oval connector shape, and OE-spec replacement design make it a practical choice for BMW diesel service work. This part number 1812259 is a direct-fit option for rear EGT sensor replacement on 2014-2018 BMW 328d and 2014-2018 BMW 328d xDrive models.

This part cross-references Bosch (e.g., EGR493, ETS152) for the same application.

Common Issues This Sensor May Address

• Fault codes related to exhaust gas temperature readings
• Incorrect ECM temperature input from a failing rear EGT sensor
• Emission control system performance concerns
• Diesel engine management issues tied to exhaust temperature monitoring
• Driveability problems caused by inaccurate sensor feedback

Installation Notes and Tips

Verify the connector shape, terminal count, and rear sensor location before installation. On BMW 328d and BMW 328d xDrive diesel applications, confirm the existing sensor matches the oval, 2-wire blade-terminal configuration and the rear position listed for this part number 1812259. Inspect the harness connector and surrounding exhaust components for heat damage or corrosion before installing the replacement sensor.
