I got the 'get out of the road, shut down the engine and call Porsche" message with the engine stone cold, having driven a mile and a half, sitting on the parking lot of my phone company, with the ignition on, the engine off, while trying to sort out the CarPlay! WTF!
I looked the fault message up in the Internet and got the news about the faulty reservoir sensor, the Service Bulletin number and fired off an e-mail to the SA. He asked me to bring the car over. They couldn't even open the coolant tank cap, until they got a HUGE pair of adjustable pliers. They said the coolant was a little low, but not low enough to trigger a message. They talked to Porsche and concluded that they would fill the reservoir properly and monitor the issue.
Half an hour later the car was washed and ready. I asked to see the reservoir with the cap off. They couldn't take the cap off! Here come the giant adjustable pliers again... I asked them to try another cap from another 718. They hand tightened it, they needed the giant pliers again. The neck is too big! Apparently they can order a cap and neck. A week and 4 hours later, I could remove the cap myself, without using my giant adjustable pliers (I have a pair too...). I had all this in writing, because if the message appears again when I am doing Route 66, they are going to pay for hotels and meals and everything in between...
I didn't get any problems since...
