Fault symptom

NOTE: Diagnosis has been improved in more recent software which means it is no longer necessary to change the throttle body. The software providing enhanced diagnosis is available for all model years and engine variants.
The throttle body must be reset mechanically following SPS programming (Service Programming System). If this is not done, other DTCs will be generated after several running cycles.
MY02 and later vehicles have this software. Perform regular fault diagnosis.
