ABS suddenly OFF

[s4_rider]

If it is a coincidence or not but at 160 km/h my ABS goes off, i.e. the dashboarlight comes on. Tested it on gravel and indeed the ABS is OFF. Are the sensors worn out and/or dirty and cannot follow high traveling speeds anymore ?
Shutting down the car means resseting this ABS phenomena until you drive 160 again.

Or was it the hot weather ?

Regards,

I've had this. You'll probably find that with time, the speed required to make it switch off gets lower and lower.
Its a dirty sensor. VAG-COM will tell you which wheel is at fault. Cleaning it should help, although you may end up having to replace it.
