Hi,

I suspect you may have issues involving the Electronic Immobilizer (also called the Drive Block in Porsche Parlance). It could be a bad Ignition Switch, or the electrical Connection to the Immobilizer itself, or finally, the fuse for the immobilier.

The Interior Lighting is controlled by this unit, and the Unit runs through the Ignition Switch. The Immobilizer is located under the Passenger Seat and has a separate 15 Amp fuse in the Immobilizer Unit itself.

To access, first disconnect the Battery (be sure you have your radio code if applicable). Next, you'll need to remove the Passenger Seat. Then you'll see the unit mounted to the floor. You'll need to release it from the Floor Anchor by turning the Locking Clip ¼ Turn Anti-Clockwise. Now turn the Unit over and you'll see the electrical connector and the 15 Amp Fuse. Be sure there is no corrosion on the connector and that it's good and tight. Next, run a continuity test on the Fuse, don't trust a visual only check. If these don't help, then I suspect your ignition switch may be bad (even though it still works to start the Car etc., it has several different functions, including an Induction Coil for the Immobilizer). Replacement is more difficult, even though the Part is under $30. If interested in doing this repair, PM me and I'll send you the procedure. Hope this helps...

Happy Motoring!... Jim'99
