plastic chain tensioner pad material. common - lots of info about it on this forum. you may see the associated increase in cam deviation as the pad wears, and hear the 'startup rattle' as the chains slap on the pads and chew bits off. the replacement oem part is of a harder material and appears to be a cure. in the interim try an oil with a heavier cold weight so that there is some oil on the pads at startup. not much else to do; the engine will throw a cel when the pads wear enough to cause a cam deviation that is of concern to the computer (Porsche spec is max 6 degrees, but the cel doesn't seem to trigger until 9 or so I think).
