You'll get informed from Sant'Agata directly if a) you are registered in their database as the current ower and b) if the campaign is very important (but not a recall). I once got the letter regarding the steering campaign on my G.

I recall that this noise may be caused by the retainer springs holding the pads. Removing them eliminated the noise but I haven't seen a word of what may become bad when the springs are not there. So it would be helpful if the owners who had/have the same issue would tell us how it got solved. I haven't driven my Spyder much so far and I once heard a squeeqing sound in rain when stopping at very low speed or like a stop and go traffic.
