I bought a Ford Streetka from a dealer on 15.07. After 5 days in use, the engine control lamp lit up once. The ADAC read out the error and after about 50 km it reappeared. When I called the ADAC for the second time they advised me to check the catalyst and the Lambda probes. After I had called the Hander on the 29.07 I should make a workshop appointment. When I bought a Pro Garantie comfort Plus I had completed a Pro Garantie Plus and when I read it in the booklet, there was never anything about a catalyst anywhere. Do you know how this is legal? How should I behave if the cat is not included in the guarantee scope, since the error occurred already within the first week?
