my neighbour had 2 weird problems recently.
(on his 2005 911 Carrera 4S)
about 3 months back, rear passenger side suspension coil broke.
this happened whilst parked. back was lower, he thought strange. found a small chunk of coiled metal.
He got both rear springs replaced under warranty from Porsche,
Then 2 weeks ago, same thing happened, this time passenger side, front spring!!
Again, parked. Someone said they hear a loud bang, then his alarm went off.
so again, Porsche replaced front two this time.
Is this a common problem for Porsche? or just an oddity
