. This code typically appears when there is an interruption in the data flow between the radar sensors (used for safety systems) and other control modules, such as the steering or drivetrain units. National Highway Traffic Safety Administration (.gov) Quick Verdict: Can You Ignore It?
Recommendation: To verify the exact Mercedes OE number, the physical label on the unit must be inspected. Look for a 10-digit number beginning with A (e.g., A204... or A211... ).
Initial research indicates that the designation "U11A600" does not correspond to a standard, serialized Mercedes-Benz Original Equipment (OE) part number (which typically follow formats such as A168.xxx.xx.xx or N.xxx ). mercedes-benz u11a600
Not exactly. P0106 is the generic OBD2 code for manifold pressure plausibility. U11A600 is Mercedes-specific and often provides more detail (e.g., which sensor B28/7 is at fault).
To understand the U11A600, one must first speak the language of Mercedes-Benz’s internal parts classification. The "U11A" prefix typically points toward a specialized mechatronic or electrical actuation component—commonly a solenoid, a control valve, or a small positioning motor. The "600" suffix often denotes a specific variant or a higher-performance revision within that family. While Mercedes-Benz guards its proprietary part numbers closely, cross-referencing with technical service bulletins and parts databases suggests the U11A600 is an , likely found in the late-W204 C-Class, W212 E-Class, or W166 M-Class vehicles equipped with the 7G-Tronic Plus (722.9) transmission or the ADS Plus (Adaptive Damping System).

Adaptive cruise control (DISTRONIC), blind spot monitoring, or emergency braking may stop working. Red Triangle:
One such diagnostic trouble code (DTC) that can cause confusion for owners and technicians alike is the . This article provides an in-depth look at what this code means, why it occurs, and how to address it. What is the Mercedes-Benz U11A600 Code? in rare cases
Mercedes-Benz acknowledges the U11A600 issue in official documentation. A technical service bulletin (TSB) with the number addresses a specific complaint: "Message in instrument cluster: 'active brake assist function restricted'". The bulletin notes that the driver assistance systems are "temporarily unavailable" and, in rare cases, can be caused by a "brief interruption in the power supply to the LRR (B92/12) or A108 (Active Brake Assist)". The prescribed remedy is not a part replacement, but to "perform new SCN coding at BC_R (N10/8)". This underscores the importance of checking for and applying the correct software solution before replacing any hardware.
