I've noticed that when I wake up my 991 and it is still very cold, 3-point turns feel very bumpy and funky when the steering is at its extreme...almost as if the wheel is catching a mudflap, or the brake-hold function is repeatedly engaging and releasing. Once the car is warmed up I can no longer reproduce this effect.

Have any other 991 owners noticed anything like this?

 

that happened in my Cayenne turbo - PDCC would clunk. there were a lot of comments on it at the time

 

I have not experienced this (No PDCC).

 

Further searching has revealed what appears to be my problem.

The fronts have a lot of caster and the cold tires are scrubbing on 45 degree turns until the tires warm up and get flexible.

"Working as intended"

 

completely normal. Its the binding of the tire camber.

 

Sorry to change the topic-but how is your car doing Eric? Are you enjoying it? My cab should arrive in another 2-3 weeks.

 

Hasn't been cold enough to experience any thing like that. Will let you know how it behaves in 140 F this summer.

 

WHAT.... This sounds like a defect.

 

These threads all cover this fairly extensively and seem to confirm with confidence that it is not a defect, but is indeed "working as intended":
