Yes, one of them is a TOB going bad. It goes from silent to whirring to grinding to screeching to howling (as it stops and is pushed into the rotating clutch pressure plate fingers).

Another common sound is the HPFP (High Pressure Fuel Pump). It can be silent .... it can tick ... it can chirp (like crickets) ..... it can go rat-a-tat-tat ...and many other sounds ...... depending on type of fuel, temperature, engine speed (fuel demand), and phase of the moon (seeing if you're payen attention).

Like my oncologist tells me ....... "no change is good"; so, if sounds don't get any louder/worse, your car is most likely OK.
