Manufacturer summary
Original wording in English
Tech Tips (CBEA, CJAA, CKRA engine codes DPF replacement and/or DTCS P2413, P2463): This document informs of the use of aftermarket air filters such as cotton bed steel mesh or cone style, can cause the MAF sensor to not read accurately, affecting vehicle performance and critical monitoring functions for the diesel particulate filter. This can also result in premature DPF failure. Only use factory air filters. The use of aftermarket air filters is not supported as the system was designed and calibrated to work with factory air filters.
