Mercedes-benz U11a600

[Radar Sensor / Bumper] ---> [Moisture/Corrosion] ---> [CAN Bus Disruption] ---> [U11A600 Error] Moisture and Environmental Contamination

As noted in technical service bulletins, the U11A600 code can sometimes be wrongly stored in the steering control unit (N68) during diagnostics.

If corrosion is found at the sensor connector or a broken wire halfway through the harness, expect 1–2 hours of electrical diagnosis plus repinning or section replacement.

is a highly specific automotive diagnostic trouble code (DTC) that indicates a communication breakdown with the radar sensor system control unit . Commonly retrieved during deep electronic scans, this code is tied closely to Mercedes-Benz’s advanced driver-assistance systems (ADAS), including Active Lane Keeping Assist, Distronic Plus (adaptive cruise control), and Collision Prevention Assist.

Are you currently seeing a on your dashboard, or did this code only appear during a diagnostic scan ? Fault code U11A600 stored steering control unit - nhtsa

Mercedes-Benz explicitly states that if the code appears without active dashboard warnings, . The steering functions work perfectly without restriction, and the code is simply an error in the XENTRY Diagnostics software platform. Vehicles Most Affected

If your issue occurred after driving in heavy rain or a car wash, you should:

If the above steps fail, you will need a professional to use the to pinpoint which sensor is causing the malfunction and check for CAN bus communication errors.

Modern Mercedes-Benz vehicles are marvels of engineering, relying on an intricate web of sensors, control units, and communication networks (CAN bus) to operate advanced driving assistance systems (ADAS). When these systems fail to communicate, the vehicle will log diagnostic trouble codes (DTCs). One such specialized, yet sometimes misleading, fault code is .

Remove the radar sensor from the rear bumper (or front, depending on which system is reporting the error). Inspect for water damage or corrosion on the pins.

In rare cases, the radar sensor itself or its mounting bracket may be damaged or out of alignment, often after a minor front-end collision. Commonly retrieved during deep electronic scans, this code

In many cases, Mercedes-Benz has identified that U11A600 is actually a . According to official technical service bulletins (such as LI46.35-P-069432), the code may be displayed by mistake when reading out data through XENTRY Diagnostics on certain models.
