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.
- [23 14 31 2038105](/bulletins/10212650.md), 2022-05-31, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION. Production tolerances in intake hose can cause amplification of normal turbocharger noises. Customer states excessive turbocharger resonance or intake air noises during acceleration. The concern can be reproduced at approximately 30% throttle loading and medium RPM.
- [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 19 2036113](/bulletins/10210657.md), 2022-05-02, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:GEARS. The Park position of the gear shifter is sporadically not recognized, which causes the ignition key to not be cleared and prevents the vehicle from being locked.
- [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.
