Has anyone experience whining sounds from the rear on a 997.2+pdk+LSD????

I have been going back and forth to my dealer with this problem. FInally they decided that this is standard with the LSD option with PDK, that there is a slight whine in the rear differential between 10mph to 60mph. This is not the grind or crunch sounds that come with the LSD while turning. This is WHINING, and it is very faint.

Thank God the technician heard it. Usually they dont admit.

Has ANYONE heard any such sounds? whether with or without LSD option?

I took tourist delivery last month of a Carrera S with PDK and the sport suspension option which includes the LSD. In the 1200 miles I put on the car in Europe I can't say I noticed any unusual noises from the diff. Unfortunately, the car is not back in the States yet or I would take it out for a drive right now and listen more closely for the noise you describe. If you can wait a couple of weeks or so I will follow up on this when my car arrives.
