As per title really, the reason for asking is that my S3 went into the dealers today for amongst other things an annoying vibration through the steering at motorway speeds. I have had the wheels balanced several times and swapped front to rear in case a tyre / wheel was duff. But the fault remained.
Anyway the dealer said they could not replicate the problem but that the antiroll bar and bushings needed changing ( under warranty thank god! ) So the question is what does the antiroll bar do ( ie how does it work ) and could this be the cause of my problem. The freindly ( but no use at all ) service receptionist knew less than me.
Any feedback would be appreciated !
