Did you check the toothed trigger ring on the drive shaft was not damaged? I'm not sure which type the punto uses but most cars use a shrink fit metal ring, because the are under constant tension they can be prone to cracking.
If this is the problem the official fix is often a new drive shaft but a bit of delicate welding has been known to save the day.

I suggest the above because it sounds like the diagnostic pointed to a specific cause.

Check the abs plug/ wiring for water ingress and corrosion there have been cases where people have had the front abs loom replaced (do a search I can't easily at the moment I'm on my mobile ) :-)
