My XC 90 T8 makes me happy with this error message since the weekend. The brake is easier at the beginning of the brake pedal path and then beats even harder. Brakes are possible without any problems. The hybrid mode is also disturbed: when the burner runs the first time it runs out immediately when the load is removed, where it always runs through a round to get to minimum temperature. (10 keys in the GCW version unsuccessfully.) Is there any experience with this error? Greeting Thomas
