I have a 997.2. it makes this high pitched noise at start-up. it goes away after car is warmed up. Anyone know what this could be?
Thanks!

Wow, never heard that before..... I suspect that it is related to some of that aftermarket stuff.... but I really don;t know.

Check the fluid and if it's low, find the leak. That's a closed system so the fluid level should never change. If the level is low and one of the lines or fittings isn't leaking, pull the boots at the sides of the steering rack up front and I bet they're full of PS fluid, which means the seals on the rack have failed.
