On my mates Mk4 i think it is (t Reg) Polo 1.4CL on his dashboard his Airbag light is constantly on now there a problem with his airbag or just an electrical and if so how does he sort it out?
take it to a main dealer or someone with vag-com & get them to take a look. Airbag could be faulty, sensor could be bad or simply a loose connection.
