Recently acquired knowledge means that after replacing the pressure sensors on the exhaust aftertreatment unit, the previously specified teach-in process in the exhaust aftertreatment (ACM) control unit is no longer used. It has been shown that vehicles with high kilometer readings may have fault messages again after only a few days. In XENTRY the corresponding selection option in the Teach-in process category will be removed as soon as possible. The work instructions have already been updated.
