Yes, I came across that too, based on that info the engine should be 2005 or newer. Now, looking at the Bentley manual, looks like the 3-chain engine with the redesigned variocam came out in 2003, but this engine is definitely a 5-chain. It`s possible that this IMS is not its original. Or perhaps this was a factory replacement engine which Porsche built after 2005 with the newer IMS but with the early variocam system to match the DME
