Hi, It's been a while since I actually posted here, but I was hoping to get the help and advice I greatly appreciated in the past. I have a 2004 S and I encountered a strange situation yesterday. I was out to buy some gas to top off the tank for the winter storage. The engine was warm, the Boxster was performing extremely well and dusk was approaching.

I turned on the headlights, the oil pressure warning light popped on and the lifters started hammering. Pulled off the side of the road, turned off the engine and lights, waited a few seconds and restarted the engine. No warning light, no lifter noise! Turned on the headlights again and yhe warning light and lifter noise started again.

I shut off the engine, waited and restarted. Turned on the parking lights and fog lights and had no issues. Drove it home and parked the car in the garage. Just for information's sake, I do have a set of Nine8Six's BiXenon projectors installed (Not blaming them) Could the head light switch cause a problem with the delivery of oil to the engine?

Thanks in advance for your help.
