Hi Thierry242
my car is 2020 P4 and will get the brakeupdate this week and the the 3.Radiator!!!!.
my dealer in Germany -Flaving- has the opinion it might be a fault of the radiator fixing and therefor a construction problem of the factory.

I m really curious about it-how long will the rad work without fault…….

and :what about the warranty……….what will MCC offer after the 24 months warranty?
