Technical Service Bulletin SIB010921 — 2019 BMW 640I

Component-Specific Limited Warranty Extension. For the eligible vehicles, BMW of North America, LLC (BMW NA) is extending the limited warranty for the vehicle's Leak Diagnosis Module with hose assembly (NVLD, shown) to: 15 years/150,000 miles as determined by the vehicle's original in-service date. For eligible MY 2017 BMW 530i Sedan and xDrive (B460) vehicles that are currently registered in the State of California (CA) or a State that has fully adopted the State of California PZEV/SULEV regulation (CT, ME, MD, MA, NJ, NY, RI, and VT), the standard component-related coverage for the NVLD is 15 years/150,000 miles. This component-specific limited warranty extension applies to defects in materials or workmanship. This coverage is subject to the same vehicle eligibility requirements, limitations, and exclusions that apply to the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks. Over time, the Leak Diagnosis Module (NVLD) (with connected hose) component material may fail, this can create a fine leak to develop in the Evaporative Emission Control System (EVAP). Should this occur, corresponding fault codes will be stored in the DME memory and the MIL (Malfunction Indicator Lamp) will illuminate.
