Interested to know if you determined what the problem is. Did you get this resolved? A colleague of mine has a 981 Cayman and described a similar symptom that occurs just before the car comes to a stop under normal braking.

 

You file is no longer there according to dropbox. Mechanical clicks at low speed, primarily while turning can signal differential problems. Does it only happen with while turning?

 

Here is fresh link, hope it will work better

It sounds as a very mechanical sound, and happened occasionally over few days. Once during a sharp turn, the one on the video is while going straight. The dealer could not find anything wrong and since then it did not happen again.

 

Boxsters, Carreras and 928s all have transaxles.

The latter has a torque tube from the front engine to the rear.

So same fluid for both the tranny and differential? That's the techincal definition of transaxle. Many people think the Corvette has a transaxle just because both are at the back, but they're separate units bolted together, with separate fluids. Being RWD, I was almost sure Porsche had transaxles for both cost and space savings. I'd simply change the fluid more often, especially with LSD (PTV), since its clutches contaminate the fluid. Thank you for your help.

 

Just a thought… shifter linkage adjustment. Next time it does it, see if you can "feel" it through the shift lever. Maybe move the lever slightly and see if it stops or gets louder.
