ABS wreaths

Moin Moin… I need your help here.. 5 weeks ago we bought a Smart Cdi Cabrio. Total class of dare. Now we have been to a smart dealer to have an inspection done, which has determined that the ABS wreaths have broken. Where we bought the car he says it’s all OK & he can’t read anything. It trits even if you are very slow below. What do you say??? continue until nothing goes on??? the reperature should cost good 800€ since d he wreaths are mounted on the truss & it will not be individually… For your help I am grateful… Greetings Lars
