Check Engine Light

[MBEEZ911]

This morning I started up my 911 and drove to Costco to put gas (91) into my car. Everything was working fine :) I returned home, parked the car in the garage and then ate some breakfast. About an hour later, I started my car and noticed the "check engine light" was illuminated. In addition, the red light next to the fuel gauge and the red light next to the temp gauge were also illuminated. I thought for sure that I probably didn't secure the gas cap properly. I unscrewed it and then screwed it back on firmly. I then got into the car and drove for about 2 miles. The lights did not go off.

I drove (apprx. 5 miles) the car to my local independent mechanic, Autobahn Motors in Tracy, Ca. The "master mechanic" who works on Porsche's was on vacation (returns Oct. 25), but his assistant tried to clear the codes with his hand held device, but was unsuccessful. While I'm waiting for the mechanic to return, I was wondering if anyone had any ideas regarding the problem.

Recent maint: A new alternator & battery in August. An oil change 2 weeks ago. Current mileage is 40,800.

Without the actual fault code(s) everything is guess. There a maybe 300-400 faults that can turn on the CEL.

My local auto tech's asst called a friend at a Porsche dealership and described my "check engine light," temp light, and gas gauge light all being illuminated. We checked the engine compartment area and noticed the coolant was below the minimum. He added Porsche coolant, let the car sit for 10 minutes, and then started it up. All of the illuminated lights were off. Problem solved for the day.
