noise when switching off running engine

[crm]

Evening,
is there any reason why an S2 1200ts should return quite a loud single metal on metal clank when the ignition is turned off ?
appears to emanate from the RHS. I'm rather hoping they all do it mister.

Its when they start make a slipping noise when trying to start that you then got to worry
