I just received an error message.."cooling system fault....service required"
Has anyone else gotten this message?
It was at the end of a 120 mile trip.

Hey @klhTaycan, did this happen while you were driving or after your finished your trip? Have you taken it in to get looked at?

I was first aware of a problem when Porsche Connect indicated an error in the pre-heating routine prior to driving. Then, when driving about 120 miles, I didn't get any heat, just cold ventilation.
Finally, toward the end of the trip, the error message popped up.(image below)
The tech suspects a vacuum valve has malfunctioned. It doesn't seem to affect drivability...battery temps function normally.

Have the car looked at by the dealer. The cooling system is reported to have 300 distinct states. If the fault becomes severe enough the car will stop being driveable to protect itself. This will probably happen at the most inconvenient point in your drive. There have been reported incidents of loss of refrigerant too due to improperly installed O-ring. Good luck.

Thanks...it will go in on Wednesday...I am told all repairs need approval from the mothership, and parts will likely be shipped from Zuffenhausen, although I know some parts are inventoried at the Easton, PA logistics center. I ran into somebody while at the opening at Watkins Glen today, who said he had heard of a faulty coolant level sensor creating problems.

As it turns out a stone created a radiator leak...see the photo below. Be forewarned...these radiators are too exposed for comfort.

Oh wow that's a decent ding from the stone. Has the radiator been fixed/replaced?

The radiator was replaced, and I plan to repair the damaged radiator, just in case it happens again. It might have been one of those rare incidents, but on the other hand, the Taycan radiators may be more exposed, due to the louvre configuration. I have never had this happen on my other Porsches, in over the more than 200,000 miles driven.
