  Summary

  This NCU replaces the prior NCU issued on July 30, 2021 and includes an additional population (33) of certain MY 2018 Baumusters covered under this extended warranty. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has extended the warranty on the low pressure fuel hose that connects to the high pressure fuel pump, from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 10 years/120,000 miles (whichever occurs first) on certain Model Year (“MY”) 2015-2018* vehicles. This warranty extension includes the replacement of the fuel hose due to potential fuel weeping on the fuel hose at the inlet connection to the high pressure fuel pump. Under certain cold ambient conditions during a cold start of the engine, the low pressure fuel hose at that connection may experience slight fuel weeping. A brief odor maybe perceptible by the occupants, but a safety risk, including the risk of fire, can be ruled out. This extended limited warranty applies to all aforementioned conditions that necessitate the servicing and / or replacement of the fuel hose under the standard warranty terms and conditions. The extended warranty is applicable to the following vehicles, which are flagged on a VIN-level basis in NetStar:

  This NCU replaces the prior NCUs issued on October 30, November 09 & November 20, 2020 and contains clarification on the replacement of the Camshaft Adjuster under this extended warranty. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2012-2015 Mercedes-Benz Model 204 and 172 vehicles (C250 and SLK250), the warranty on the camshaft adjuster will be extended from the original 4 years/50,000 miles to 10 years/120,000 miles (whichever occurs first) from the original warranty start date.
