You should download or order a copy of 101 Projects for Your Porsche Boxster by this forum's owner.
It's a must own book. I keep a copy on all my Android devices. It lists every common repair and maintenance fix and shows icons for price of parts, estimated labor time and degree of expertise needed. And get one of those bluetooth OBD II plug ins to use with your smart phone. Very useful for those CEL lights that come on during a long drive home in the middle of the night.
