Blown master cylinder

Yesterday morning I went to start my car (after sitting from saturday evening and it was pretty cold maybe -10*C) and it wouldn't get into gear, so right away i knew what was wrong, a part of the clutch system broke. So i got it towed to the dealership where they first said they might not cover it under warranty becuase it is normal wear and tear (as if). Well anyways they looked into it and it turned out the master cylinder blew. This they couldnt pass off as normal wear and tear and repaired it under warranty.

So just thought I'd make a post about this.
