An AdBlue message may appear in the instrument cluster either because there is a fault in the emission control system or because the system needs to be refilled. The AdBlue message displayed may vary depending on the model year of the vehicle.
- [37 14 21 2036826](/bulletins/10210670.md), 2022-05-02, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); UNKNOWN OR OTHER. Diagnostic threshold setting in current software is too sensitive. The following message appears in the information display: ?Gearbox malfunction: You can continue driving.? New software in the TCM addresses the condition.
- [37 13 98 2025754](/bulletins/10210667.md), 2022-05-02, Service bulletin: ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION MOTOR; UNKNOWN OR OTHER; POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). The vehicle pulls away with a jerk and slightly increased engine speed. There are no fault entries in the transmission control module. The vehicle hardly tends to creep in driving mode D and R. When pulling away, a jerk can be felt. The gear changes are uncomfortable.Shifting concerns while cruising or kick down. Shuddering or jerking when in R. Harsh gear engagement. Improved software of the transmission control module.
- [37 13 09 2028715](/bulletins/10210652.md), 2022-05-02, Service bulletin: ELECTRICAL SYSTEM:12V/24V/48V BATTERY; POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:GEARS. After a mechatronics, torque converter, or complete gearbox replacement, the clutches must be adapted to the new component. This requires a gradual move of the clutch linings toward the optimal operating points in the most diverse load conditions. As a result, sporadic driving power disruptions lasting for less than a second or reduced shift comfort are possible over the first 500 miles. This is normal, and these issues will decrease over time. The issues can also occur if the adaptation values of the gearbox were deleted.
