: In many instances, U11A600 is considered a "ghost code" shown by mistake when reading data through XENTRY Diagnostics. If the steering functions normally, the official recommendation is that the fault code can be ignored .
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.

The steering functions and safety systems typically continue to operate without any actual restrictions, even when this code is present in the "stored" memory.
: Model 247 (A-Class / B-Class / GLB) and related MFA2-platform vehicles equipped with lane keep assist or radar packages. : In many instances, U11A600 is considered a
Yes. A stored U11A600 will cause your vehicle to fail emissions testing in states that use OBD2 plug-in inspections (California, New York, etc.). The monitors will show "incomplete."
Depending on the specific Mercedes-Benz model and the module reporting the code, this error can either point to a physical component failure within the Advanced Driver Assistance Systems (ADAS) or exist simply as a known software glitch. The Crucial Diagnostic Exception: When to Ignore It Commonly retrieved during deep electronic scans, this code
The radar sensor, often mounted behind the front bumper mesh or the central Mercedes-Benz star grille emblem, relies on a precise field of view. Heavy accumulation of mud, snow, ice, or road grime can block signals. Additionally, minor parking lot bumps can jar the radar bracket out of its strict alignment window (often requiring a tolerance within ±3∘plus or minus 3 raised to the composed with power 2. Water Ingress and Corrosion
When your Mercedes-Benz performs a self-diagnostic scan, the presence of the U11A600 fault code indicates a specific issue: . Essentially, a primary control unit, such as the Drivetrain Control Unit (PTCU) or the power steering control unit, cannot reliably communicate with a radar sensor module.
It can be safely ignored . The steering system and driver assistance functions will perform normally without any real-world restrictions.
Intermittent symptoms are the hallmark of U11A600. The car may drive perfectly for a week, then throw a dozen errors simultaneously for 30 seconds, then return to normal.
