SUBJECT

Model EQE and EQS (294 and 296 platform) 

Model Year 2023 

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2023 EQE (294 platform) and EQS (296 platform) vehicles, the SCN coding of multiple control units does not correspond to current specifications. In this case, it is possible that error messages may occur during future software and SCN coding updates. An authorized Mercedes-Benz dealer will update the SCN coding for the control units in the affected vehicles.

Prior to performing this Campaign:

• VMI must be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns and perform accordingly.
• Please review the entire Campaign bulletin and follow the repair procedure exactly as described.

Approximately 34 vehicles are affected.

Order No. P-SC-2024060004

• Always use the latest  XENTRY Diagnosis software release with all available add-ons.
• Follow the operation steps exactly as described in XENTRY Diagnosis.
• Use a charger to ensure sufficient power supply to the vehicle's on-board electrical system battery  (greater than 12.5 V).
• If XENTRY Diagnosis is already connected to the vehicle, start with Work Procedure Step   2 . 

  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.
