Update Software for Various Control Units – Wave 1

This is to notify you of the Service Campaign Launch to update the software for various control units in 2,015 Model Year (“MY”) 2022-2023 EQS (297 platform) vehicles. The vehicles will be visible and flagged in VMI as “OPEN” on August 22, 2023.

 

Issue

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2022-2023 EQS (297 platform) vehicles, the software for various control units does not meet current specifications. An extensive optimization update will be implemented on the affected vehicles. Also, a special procedure has already been implemented in Xentry. The software updates will include, but are not limited to, increased system robustness, increased augmented reality camera quality, implementation of the Zync-App for video streaming via the head unit, and implementation of Dolby Atmos for an improved audio experience.  

 

What We’re Doing

MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the control units.

 

Parts

  • Should you require any support, issues must be documented with an XSF ticket with subject “QO297“

If two or more software updates or SCN codings are performed during a single workshop visit, operation items 02-4762 and 02-5058 may be invoiced only on one of the workshop orders.

 

Work Procedure

It is advantageous to always use the same XENTRY Diagnosis for the software updates. The entire software must always be re-downloaded per device (up to 18 GB).

It is mandatory that a VCI connection is established via cable.

LAN wired Xentry is recommended for a faster download speed and a stable connection.

The flash procedure should be started in the morning and cannot be interrupted.

The flash could take several hours.

 

  1. Connect XENTRY Diagnosis and verify all the latest ad-ons are installed. The cable to the VCI must be routed through a rear side window.

The front side windows and front doors must be closed.

During this process, the front seats are moved to their end positions. The VCI cable must be positioned such that it cannot be pinched.

Via the orange special menu item,  start “Control unit updates are available for this vehicle” (Figure 1).

Then follow the user guidance in XENTRY Diagnosis

 

  1. Update “Parking control unit”

To do this, select and start menu item #1 – N62/3 (Parking system control unit), (A, Figure 2).

Then follow the user guidance in XENTRY Diagnosis.

 

Update “All control units” software.

To do this, select and start menu item #2 (All control units), (B, Figure 2).

Then follow the user guidance in XENTRY Diagnosis.

 

  1. Verify all control units are completed (Figure 3), repeat Work Procedure step 2 as needed.

 

  1. Clear fault memory

 

  1. Disconnect XENTRY Diagnosis.
