Thierry- I currently have a leak in the radiator of my Plus Four. My dealer put a radiator stop-leak product into the rad as a temporary solution till the new radiator arrives. This was 3 weeks ago and so far it has stopped the leak so I can drive the car. I am obsessed with the temperature dial though!!!! I don’t know when the radiator will arrive from the factory it is on back order I believe!
This is a most annoying development as I am really enjoying the new car
Cheers
