I drive a shuttle 2.2 ES, built in 1996. For some time now the SRS warning light has stopped running. It has already been “defaulted” 2 times with the customer service, but after about 2 months it went on again and again. My question: Does anyone know how to turn this light off or reset it? A control unit should cost up to 500 euros extra installation. Can it be that only the warning light warns, but the airbag is functional? Greet ….and thank you for the help Stefan
