How can I reset the service light? My car hasn´t got the diagnostic unit (a and b)like the models till this year.

Answer
Paco,
If your car has a YASAKA instrument cluster you will see a small rubber plug on the glass, pull the plug and push the button. If your cluster is the VDO you need a reset tool or scanner to plug into the OBD II diagnostic plug and reset the light.
