On what? The service light may or may not be relevant to your fault,it could signify DPF regeneration problems which depletes the oil condition hence the service light comes on or it could simply be a mileage reached and is telling you to service the car. Your best bet would be to get it onto a relevant computer/code reader and this will reset your light and also access your airbag/body ECU to see what is wrong there.
