My Punto Sporting 1.2 16V (2003) has a strange (electrical) error. When I
hit the brakes the (red)airbaglight comes on now and then. Went to the
dealer some weeks ago. He found no errors in the main computer so he
replaced the airbagmodule. Problem solved, it seemed. But no, after a couple
of weeks of failure-free driving the same error is back. Anybody around here
familiar with this problem and (maybe) knows the solution? Thanks in

It's a good site for technical info.
Used it several times for "How do I remove" or fix type jobs.

Fiats seem to suffer from earthing related problems, plus

Maybe there is a duff production run of marginal
airbag modules and the replacement was from the same

Battery OK, connections clean and firm, brake lights put

Thanks for your quick reply, Ato. I'll try your suggestion and will have a

By the way, connections and battery are ok; battery is fairly new (4 months
old) and the Punto has only done 24000 km. yet. Car is maintained very well,
but that doesn't say it all, does it!
Follow-up: had my Punto to my Fiatdealer today. He confirmed it could well
be a faulty ignitionswitch, although it is not a common problem, he said.
Had the switch replaced (under warranty; for a 3 year old car: way to go!)
so we'll see what happens next. Looks fine for now. Thanks everybody!
I've had severa Fiat ignition switches fail, one a melted
contact block, another mechanical failure (front lift recovery
job as key wouldn't turn - even with a lot of WD40).
They are a pain in the arse to replace because of the
snap head security bolts, when the drill breaks
you have the hardened stub to remove.
Now I use ordinary hex headed bolts to fix the
Can't see anyone tackling the column shroud to
get at the switch to nick the car.
Next time round the switch comes off easily.
