Why does my turbo sound like it's ticking?

[domharris9]

Whilst my engine is running there is a ticking sound that sounds like it's coming from the turbo. This continues for a second or two after the engine is turned off. Any ideas what is causing it?

 

 Thanks

Mine ticks after its been turned off mainly due to heat mate, dont think its anything to worry about.
