Does it do it all the time, or just after a run?

I think it's misfiring a bit. I've just put a petrol system cleaner in the fuel tank & intend to replace the spark plugs shortly. Air filter too at some point soon. Just confirmed that all the timing chain system including tensioner was done in December 2015 so it shouldn't be that. (And was also great to learn that had been done so recently!)

Anyone else got any thoughts on the engine turn off buzz?

Most of the time but could happen when turning engine off straight from cold or after a long run.

I reckon it's something to do with a pump or the turbo.

Isn't there a pump that pumps water around the turbo to cool it?
