Same story in Switzerland. Letter advising me to charge to 80% max, meanwhile, dealer charges the car to 100% before returning it to me. Not to mention keeps it topped up at 100% the whole time it's at the shop - also not advisable for the kind of battery chemistry taycan has.
Just a clown show
In switzerland, they have it in invetory at most dealers that work with taycans. 😅 So clearly they expect these to fail often. I wonder if they redesgined it at any point, but seeing as how 2024 still fails, likely not.
Curiosuly enough, knock on wood, my 2020 never had a heater failure. But...
