Update Driving Assistance System Software
This is to notify you of the Service Campaign Launch to update the driving assistance system software on 24,840 Model Year
(“MY”) 2022-2023 C-Class, EQS and S-Class (206, 297 and 223 platform) vehicles. The vehicles will be visible and flagged in VMI
as “OPEN” on May 19, 2023.
Background
Issue
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has
determined that on certain MY 2022-2023 C-Class, EQS and S-Class (206, 297 and
223 platform) vehicles, the driving assistance system control unit software does not
meet current specifications. In the presence of uniquely shaped civil superstructures
that parallel the roadway at a height of~26-33 feet (e.g. large overhanging bridge
abutments, etc.), the vehicle may initiate brake applications during operation. In such
cases, the driver remains in control of the vehicle and can override the system at any
time.
What We’re Doing
An authorized Mercedes-Benz dealer will update the driving assistance system
control unit software.
Parts
The remedy is available and can be performed as necessary.

Update Driving Assistance System Software
 Always use the latest XENTRY Diagnosis software release with all available add-ons.
 Make sure to 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

only on one of the workshop orders.
The fault codes U05B7E1, U05B8E1, U05B6E1 and U05B5E1 appear after the software update, but can be ignored.
The fault codes U05B7E1, U05B8E1, U05B6E1 and U05B5E1 are no longer present after a short driving time.
