Correct me if I'm wrong, but I believe the clicking is the sound of the moving parts (contacts/armature) inside the relay. The suppression diode helps prevent back EMF when the contacts open (so it doesn't behave like the ignition coil on a car), so I don't think it'll affect the clicking sound.
My ex once told me I have a perfect face for radio.

That's why you're the expert Audible relay clicking sound - Page 3 - Last Post -- posted image.
So I take it you often use a diode on your relay applications right?

Always since I managed to blow up a Clifford G4 AND an Intellistart 4 at the same time around 15 years ago!
Luckily I was pals with everyone at the importers back in the day!
I remember about 2 years ago asking someone to do just that, amazingly enough he didn't listen and manged to fry both the lock outputs and the 24-pin H2 plug outputs on a 5X04, the point being, NEVER assume it's internally protected.
