If the code is accompanied by physical symptoms and cluster warnings, a genuine communication drop has occurred. Common signs include:
Sometimes the hardware itself fails. The internal processor of the gateway can develop micro-cracks in solder joints due to thermal cycling. This is a known issue in early W213 (2016–2018) gateway modules.
Gently clean the front emblem and the corners of the rear bumpers. This is the most common "DIY" fix for communication-related radar faults. 3. Inspect the Wiring Harness U11A600 can degrade into a no-start condition within
: Model 247 (A-Class / B-Class / GLB) and related MFA2-platform vehicles equipped with lane keep assist or radar packages.
Do not throw parts at U11A600. Follow this logic:
The "600" suffix typically indicates that the fault is current or persistent, rather than intermittent or historical. In some Mercedes technical service bulletins (TSBs), U11A600 is explicitly linked to a .
In modern automotive architecture, individual control units communicate over a localized Controller Area Network (CAN bus). When a master control module—such as the Powertrain Control Unit (PTCU) or Steering Control Unit—attempts to ping the radar sensor control module and receives an improper or missing response, code U11A600 is triggered. Denotes a network communication fault code.
