It's been a long time since I used mine, but from memory any "ticking" sound is the aperture adjusting. The AF motor is more of a kinda hum-whine.
There was also a firmware update for the lens in the distant past, but I'd assume any recent sample will have it anyway. Can't remember what it did.

I checked the firmware and found that my lens has the latest firmware 1.1 installed. And yes, the sounds is from aperture adjusting rather than from the AF motor.
