SUBJECT

Model C-Class, GLC, S-Class, and SL (206, 223, 232, and 254 platform) 

Model Year 2023 

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2023 C-Class, GLC, S-Class, and SL (206, 223, 232, and 254 platform) vehicles, the DRVU control unit does not correspond to current production specifications. As a result, an incorrect fault stored message may appear (e.g. U188D00 and U015400) in the instrument cluster, indicating a "missing signal," when in fact such signal is not required at this time. An authorized Mercedes-Benz dealer will update the SCN coding for the DRVU Control Unit.

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 66,944 vehicles are affected.

Order No. P-SC-2024020005

• 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.
