Service bulletins for the 2021 Mercedes-Benz Sprinter

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

143 on file from NHTSA, as of 2026-10-19.

LI54.21-N-0752962022-10-05. Service bulletin. ELECTRICAL SYSTEM. Complaint Customer purchased pre-owned MY18-21 ex-Amazon Sprinter (SA code Z3A) and does not want Amazon specific Parameterizable Special Module (PSM) functions (driver alert, idle shutdown, radio mute, etc). IMPORTANT NOTES: • Digital rear view display will no longer operate after Amazon specific PSM software is removed! • MY18 will show the reverse camera image on the Audio 15 screen. • MY19-21 will lose reverse camera functionality completely! Cause Strategic fleet customer removed the OEM rear view mirror with integrated reverse camera display to install an aftermarket digital rear view display that gets its power supply and reverse signal from PSM. When the Amazon-specific PSM software is removed, the aftermarket digital rear view display no longer has a power supply or reverse signal supplied by the PSM. It is not possible for the OEM PSM software to provide a power supply or reverse signal to the aftermarket digital rear view display. Remedy 1. Notify customer the aftermarket digital rear view display will not operate after PSM software is updated, AND: Reverse camera image will be displayed on the Audio 15 screen (MY18 ONLY) OR Aftermarket digital rear view display must be replaced with the OEM rear view mirror with integrated reverse camera display (MY19-21). 2. Perform software update of Parameterizable Special Module (PSM) using XENTRY > Adaptations > Control Unit Update > Updating of control unit software. This will remove fleet-specific PSM software and load the OEM PSM software from VeDoc. 3. MY19-21: Remove aftermarket rear view display and install OEM rear view mirror with integrated reverse camera display.

LI72.10-N-0743302022-03-04. Service bulletin. STRUCTURE. Complaint Operating unit for window lifter at door is nonfunctional. The problem currently only occurs at the driver's door. Cause Triggered by frequently opening and leaving the front doors open or frequently driving with an open window when it is raining, which results in water entering into the operating unit (window lifter). As this is a result of customer use, the replacement of the switch will not be covered under warranty. The switch cover will also not be covered under warranty as this is not a defect of the component. Remedy If the window switch is inoperable it will need to be replaced. Attach silicone cover trim over operating unit for sealing. Silicone trim has an adhesive strip and is affixed over operating unit. Bonding surface area must be cleaned and degreased prior to bonding.
