BMW DTC P24F2 – EGR Temperature/Charge Air Cooler Temperature Correlation
DTC P24F2 meaning on BMW
The DTC P24F2 on a BMW indicates a correlation problem between the Exhaust Gas Recirculation (EGR) temperature sensor and the Charge Air Cooler temperature sensor. This means that the Engine Control Module (ECM) has detected a discrepancy between the expected values from these two sensors, which are crucial for the proper operation of the EGR system.

How to diagnose DTC P24F2 on BMW
To diagnose the DTC P24F2 on a BMW, a mechanic would typically use a diagnostic scanner to retrieve the fault code and then perform a thorough inspection of the EGR system, including testing the EGR and Charge Air Cooler temperature sensors, checking for wiring issues, and verifying the ECM functionality.
How to fix DTC P24F2 on BMW
Fixing the DTC P24F2 on a BMW usually involves replacing the faulty EGR or Charge Air Cooler temperature sensor, repairing any damaged wiring, cleaning the EGR system of carbon buildup, or reprogramming the ECM if necessary. It is recommended to follow the manufacturer’s repair procedures and use genuine parts to ensure proper functionality.
How to erase DTC P24F2 on BMW
Once the underlying issue causing the DTC P24F2 on a BMW has been resolved, the fault code can be cleared using a diagnostic scanner.
