Diff bracket sheared off

[james.c]

My 3 day tour of Wales was cut short at the end of day 2 as a slight banging / movement from the back of the car (and a grinding when off the power in gear!) got worse and worse. 

When we got the hotel we found that the diff bracket seems to have completely sheared off. It's an18 month old 620S so hoping it should be sorted under warranty (BaT looking at pictures now). 

Anyone else experienced anything like this before? Also wondering what the chances are that I have damaged the diff over the 35 miles limping back to the hotel. It drove ok (especially under power) which is why I limped it back (also was in the middle of nowhere!)

Any thoughts / advice gratefully received!

  
Can't see much on this one other than a loose bolt!

Probably the easiest way to see that the metal seems to have failed on either side of the diff. Both bolts are just spinning round as they aren't connected to anything anymore!

This is rotated 90 counter-clockwise but you can see that the bottom bolt (right in the photo) is not just connected to the remains of the bracket which is now missing.
