My brother-in-law was driving my (32k miles) 2003 Boxster S today. The Boxster drove flawless as usual up the long climb to the summit of Pikes Peak, but on then on the 19 mile, 7000 foot decent, the temp light started flashing and the temp gage was pegged all the way to cold. Nothing seemed to be wrong with the car, but the gage didn't appear to be working and the warning light was flashing.
After sitting on the side of the road for a while, with no other issues perceived, he started driving it back to my place and after several miles, the gage started working again and the light went off. Temp was normal, as it was before the gage stopped working. Right now it's working like normal again. I searched the forum but didn't see this same issue. Anyone seen this problem before?
