According to a Mercedes-Benz Technical Service Bulletin (LI54.71-P-077857), the U11A600 code can also be triggered by a brief interruption in the power supply to the radar sensor (B92/12) or the A108 control unit. This could be caused by a momentary voltage drop, a loose connection, or a failing battery. In fact, a 2021 GLA 250 owner reported that after replacing a faulty 12V starter battery, they were able to resolve some of the multiple error codes the car was displaying. A weak or failing battery is a known cause of numerous seemingly random electronic communication faults in modern vehicles.
The Mercedes-Benz fault code specifically refers to a "Communication with the 'radar sensor system' control unit has a malfunction". While seeing a "malfunction" code on a diagnostic scanner like XENTRY can be alarming, this particular code often has a unique and surprisingly simple resolution.

The U11A600 error code is a manufacturer-specific diagnostic trouble code (DTC) for Mercedes-Benz. It is officially defined as: .
When the system triggers , it means a monitoring control unit expected to receive a data packet from the radar module but received nothing, or the data was corrupted. ⚠️ Common Symptoms of Code U11A600 A weak or failing battery is a known
Use a high-quality XENTRY Diagnostics tool to clear the codes. If the code is just a momentary hiccup in the CAN network, clearing it may resolve the problem permanently.
If you are driving a model outside of the TSB scope (such as a C-Class, E-Class, or GLE) and your safety features genuinely do not work, the code points to a physical fault. The most common issues include: 1. Environmental Blockages and Dirt What is Fault Code U11A600
(B-Class / GLB) and related sub-platforms (like the W177 A-Class) equipped with SA code 243 (Active Lane Keeping Assist). The Known Cause
: The front radar is highly sensitive. If the front bumper takes a minor hit (even from parking), or if the sensor bracket bends by more than 3 degrees, the module shuts down communication. Heavy mud, ice, or thick, non-factory metallic paint over the bumper emblem can also block the signal.
According to an official technical service bulletin issued by the National Highway Traffic Safety Administration (NHTSA) , code U11A600 frequently shows up as an inherent software glitch.
