Update on this "wrinkles" issue.
Did some research here in Italy on different sale platforms like subito, willhaben, etc. and it seems to be a common failure for the Like 200i model year 2010, since l found several with this mishap.
Could be, as Stig stated, really a bad batch, which slipped the inspectors careful eye.
But there is ample of replacement from later models...
and its not bothering too much.
BTW: l'm close to 48.000 km now
