Communication with control unit "Radar sensorics" has a malfunction. 🔍 The Two Main Real-World Scenarios

: If the code persists and is accompanied by a warning light, a Mercedes-compatible diagnostic scanner should be used to see if the fault is "active" or just "stored".

If your steering feels normal and no warning lights are active on your dash, this code can likely be . Mercedes-Benz service literature suggests that steering functions remain fully operational despite the stored code. 2. Clean the Radar Sensors mercedes-benz u11a600

A detailed diagnostic report on a 2019 Mercedes-Benz E300L revealed that the U11A600 code was ultimately caused by an internal short circuit within the A108 unit. Measuring the internal resistance of the faulty A108 unit showed a value of 14.7 kΩ, which was significantly lower than the 18.6 kΩ measured on a known-good unit, confirming an internal electrical fault. Replacing the A108 unit completely resolved the issue.

The diagnostic system reads this communication gap as a critical failure during a standard XENTRY Diagnostics scan . Communication with control unit "Radar sensorics" has a

: Mercedes-Benz documentation states that this fault code can be ignored , as it does not typically restrict steering functions. The Role of the Radar Sensor System

The Mercedes‑Benz U11A600 is a designation evoking a heavy‑duty, purpose‑built vehicle component or module in Mercedes‑Benz’s systems nomenclature—most plausibly tied to their commercial-vehicle or industrial-engineering families (transmission unit, powertrain assembly, or an electronic control module). This treatise treats U11A600 as a singular, high‑performance subsystem: an integrated power and control assembly designed to deliver robust torque handling, precise control, and long service life in demanding applications. Measuring the internal resistance of the faulty A108

When these primary vehicle control units attempt to ping the radar sensors to fetch spatial data—such as checking the distance to the car ahead—and receive no signal, they immediately trip the U11A600 fault code. Common Symptoms Accompanying U11A600

According to Mercedes-Benz document LI46.35-P-069432, if the fault code U11A600 is stored in the steering control unit (N68) but the vehicle is a (Lane Keeping Assist), this fault can often be ignored . The steering continues to function without restriction. 2. Check for Moisture (Physical Inspection)

If the dashboard actively flashes errors like "PRE-SAFE Inoperable" , "Collision Prevention Assist Inoperable" , or your adaptive cruise control drops out, the U11A600 code points to a physical hardware failure.

Your adaptive cruise control will refuse to activate or will abruptly turn off mid-drive.
