Thanks Geoff,
That's what I figured also I won't have the hassle of having to book it in to 2 different garages & if the fault returns who do you go to!
Rather bizarrely I went out in the car yesterday & the fault message on the dash cleared itself along with the ABS light, when I got home I switched the engine off, left it for a while re started it & the message returned so have still decided to have the work done just to be on the safe side
