Not meaning to get off-topic but the light and button you are referring to are the warning system for the car.
At least on my 85 and all cars later than that, the warning "!" and the accompanying button are to alert the driver to something not being up to spec. This could be something as simple as you have a burned out bulb to something as serious as your timing belt tension, overheating, etc. Porsche designed the system to work for both ends of the spectrum. In other words, if the problem is something not to serious, you can turn the warning lamp off by pushing that button. If it is a serious issue, the lamp will not turn off even if you push the button. There should also be a set of backlit warning indicators on your gages that will display what the specific problem is (Tension, temp, etc.)
Good news is that your lamp turns off after you hit the button meaning not too serious. Check your gages to see what is lit up!
Hope this helps.

Cheers

Except for the random debate about why Porsche engineers would deign to set a standard for the inspection of their over engineered work of art, this post was very informative.

Thanks to Tom Falkenberg for the use of one of his Kempf tools (should be Kampf given the nature of the 'struggle' involved) and the forum for setting my mind at ease on this one. Since I'm still paranoid, I'm going to wait to return the car to daily driver status when I can be sure it won't cost me an early head rebuild.

Thanks again.

From my experience, this is wrong. I haven't put the Kempf to all the different positions, but i have checked by hand and the tension between the passenger side cam gear and the tensioner does indeed vary throughout the cycle. It's easy to check, I have done it, and it does make a difference. it could be the difference between measuring in and out of spec.

He's probably got at least one indicator bulb not working, or it would be obvious why the warning is coming on.

Layton, when you first turn the key to the run position, all the warning lights should come on(bulb check). Get a strong light and look for warning lights that are not coming on with the key in this position.
