As soot accumulates in the DPF, the exhaust backpressure increases, and the pressure difference between the two hoses rises. The ECU uses this data to determine when to trigger a (burning off the soot).
or its memory (EEPROM). This often results in the car entering "Limp Mode" or failing to start entirely. Understanding the DF038 Fault
