Yep, CEL does light up when the switch is turned on and goes out after start up.....still. I'm going to start it up one more time to see if there is a vacume on the oil fill cap and from what I have read here it would seem to say yes it is the separator. If so I am temped to do it myself. I have never worked on a Boxster before but I will get a room at Holiday Inn first thing in the morning.
