Anti perforation warranty check
My C3 Aircross was registered in February 2021. My local Citroen dealership have the car today for other work and have done the anti-perforation warranty check due when the car is four. As far as I know the warranty check can be done a month before or after the registered date. Would anyone know if it will still be a valid check for the warranty as it has been done almost three months before the registered date?
