After 15 mins driving both of these lights are coming on. I'm not getting an engine check light and they clear when the car is restarted. Is there a way to diagnose this without a scanner? Do any of the eBay OBD scanners work on 996s (mine's a 1999 C4) or do I need a Porsche specific one to read everything?
