C30 SRS Airbag Service Required + Radio volume surges
My 2012 C30 has the message "SRS Airbag Service Required" which comes up several times during driving. This usually occurs concurrently with the audio system surging in volume, which can be replicated by driving around tight bends and/bumpy roads. This leads me to believe it's just a wiring fault or similar, some sort of intermittent connection somewhere. The Volvo service centre want $220 just to run diagnostics so I have been looking into getting my own Vida/Dice and DIY it.
Any recommendations or people who think they could lend a helping hand in Sydney?
