The CAT light came with my V8 already times. In the Katalisator a temperature sensor of these sits was defeckt, I the temperature sensor changed and the errors was repaired with me. Because also with me was to be determined nothing by engine misfire or overheating of the CAT's. Hope you have the same error leaves itself simply repair-wish further good travel.
