I think there is overlap, my question is about my 987, but we share parts. 2008 Boxster S, trouble with dome light, footwell lights, glovebox and trunk, all not working, not with doors open, or with switch on constant power. Lights in front trunk and doors work. Scanner tells me DTC8040 terminal 30G. I tried to reset error no luck, disconnected battery for 30 seconds no luck, I wonder if my power supply control unit has been damaged? Are these plug and play? 99761010205 is the old part number, can a used one be installed or does it require programming?
any other ideas?
