Blinking temperature light

[scott in mn]

I had a similar experience as you. I was driving through Wyoming (the worst place in the world to have Porsche problems!), and my light started blinking. I had to keep adding distilled water to my engine until we got back to Minnesota (as per my dealer). The temperature throughout the whole ordeal was fine.

Once I got it looked at, it ended up being my "coolant reservoir". It seemed like a small leak, because I kept finding only teaspoon sized puddles under the rear of the car, but it turns out that it was all over my rear trunk. Finally, on the day I was scheduled to take it in, I had a HUGE puddle under the car in my garage.

It ended up being $1,400 worth of work. Luckily, I have an extended warranty, which I would highly recommend!

Hopefully, it will be a much smaller problem, but I would have it looked at soon.
