Iain,
Thanks for the warning.
I have had a look at the fuse box on my S4 and there are three arrays of fuses - one long strip medially, one square array in the centre and one short strip along front edge.
Is the offending fuse in the small square fuse box (if so my car has been upgraded) or the short array (has one 10A fuse marked ABS in which case it hasn't)? I suspect it's the small square box which looks like engine management etc.
Robert
