Nope. If the abs light is coming on as you say, the car needs to be put
through a diagnostic with the Fiat Examiner computer which will diagnose and
possibly clear any faults. If there are repairs needed to any ecus and such,
hope car is under warranty.

But did they check the gear rim that the sensors use to determine if the
wheel is turning or not ??

That gear rim is mounted on the wheel hub, and since the hub is plain steel
it corrodes. The corrosion then sits between the hub and the rim, and sooner
or later the rim will split.
A broken or split ABS gear rim will give you those symptoms (and others):
the ABS system is confused, and cannot determin if that wheel is turning
around or not, and therefor the ABS warning light comes on.

If you drive slowly and apply your foot ligtly to the brakepedal, and brakes
just a bit: does the ABS sometimes get active so you can hear and feel it?

If your garage didn't know that a broken gear rim (due to corrosion on the
hub) is a common problem on Brava/o, Marea and Multipla : choose another
garage that knowes Fiat ;-)
