Summary

This NCU replaces the prior NCU issued on August 19, 2022, and removes specific fault codes list. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) vehicles listed below, the particulate matter (“PM”) sensor could potentially fail and consequently set fault code(s) (DTC) which will activate the malfunction indicator light (MIL). As a result, the warranty for the PM sensor has been extended from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 10 years / 120,000 miles (whichever occurs first). This extended warranty applies to the aforementioned conditions that necessitate the service and/or replacement of the PM sensor under the New Vehicle Limited Warranty terms and conditions. Please be advised that all PM sensors being claimed under this extended warranty must have a quick test uploaded with fault code information and may be audited. All PM sensors found to be functioning properly or without proper documentation will be returned and the claim debited in full. The following damage codes and parts can only be claimed for the replacement of the PM sensor: Damage Code: 14507 – PM sensor Parts: A0009050408, A0009051008, A0009051108, A0009051208 (Depending upon engine/model)
