Fault symptom

NOTE: Diagnosis has been improved in recent software, so it is not necessary to replace the throttle body. Software with improved diagnosis is available for all model years and engine variants.

The throttle body must be reset manually after SPS (Service Programming System) or other DTCs will appear after a few driving cycles.


Cars from model year -02 and on already have this software. Follow ordinary fault diagnosis.
