Reset of the SIA can be done using special tool 62 1 110 if the vehicle is equipped with the 20 pin under-hood diagnosis connector.

On 2001 MY vehicles onward without the diagnostic connector in the engine compartment, the use of the S.I reset tool is not possible. The Service Indicator may be reset using the Reset Mode in the Instrument Cluster or with Diagnosis.
