I have just been checking on the right antifreeze for my 04 996 c4 as I have just changed the water pump and according to the Comma site you should be putting in the approved Comma Xtreme G30 just check on their website also you should not mix antifreeze so flush your system anyway and refill for about 5 years of protection
