Background
To prevent contamination from affecting the reference air for the heated oxygen sensors (HO2S) new routing has been developed for the sensor wiring.
The following diagnostic trouble codes (DTCS) could be stored in the engine control module (ECM) due to harness contamination: 280A, 260A, 261A,
262A, 2A1A. Should no faults be detected for these DTCs after fault tracing according to VADIS, replace the effected heated oxygen sensors (HO2S)
and install adaptor wiring harness The new adaptor wiring harness must also be installed for the remaining sensor.
