if it helps you feel any better, mine does the same too .. exactly.
I checked the plastic bracket for the pipe that passes behind the engine near the turbo..
no luck..
mechanic couldn't trace as obviously I couldn't reproduce it in the garage..
the strength of the ticking noise seems to vary with the torque being taken from the engine,
so it could possibly be the engine twisting a bit on the mountings and something touching
something else.... wish I knew what!
