Mercedes-benz: U11a600

Mercedes-Benz fault code U11A600 signifies a communication error between the Electrical Power Steering (N68) and the Radar Sensor System, often acting as a "ghost" code stored erroneously during diagnostic scans. Particularly affecting Model 247 vehicles with Lane Keeping Assist, this issue typically presents no physical symptoms and, according to technical bulletins, can often be ignored if steering and radar features function normally. While usually a software anomaly addressed by system updates, rare, genuine faults may stem from sensor obstruction or physical damage, requiring inspection of the radar sensor housing and wiring.

Because this code involves sensitive, advanced driver-assistance systems (ADAS), the causes can range from simple environmental issues to complex electronic faults: 1. Obstructed Radar Sensors mercedes-benz u11a600

The Mercedes-Benz fault code translates to "Communication with control unit 'Radar sensorics' has a malfunction" Internal dealer or logistics code – Some regional

• Internal dealer or logistics code – Some regional distribution centers use alphanumeric internal tracking numbers.
• Aftermarket or parts supplier number – Not an OEM Mercedes designation.
• Misremembered or mis-typed code – Could be a misreading of another code.
• Fleet or rental company inventory tag – Some large buyers add their own asset tags.

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

At first glance, this code looks like a complex piece of engineering jargon. In reality, understanding U11A600 is critical for maintaining your vehicle’s performance and avoiding costly repairs. This article provides a complete breakdown of what this code means, why it appears, how to diagnose it accurately, and the exact steps to fix it.

• Sudden loss of power steering assist (if EPS loses CAN signal)
• Disabled ABS/ESP (your stability control turns off)
• Transmission stuck in park (if the shift module loses comms)

This code is typically stored in the N68 - Electrical Power Steering (ES) control unit. On the surface, it suggests that the steering system is having trouble talking to the vehicle's radar, which is critical for safety features like Active Brake Assist or Distronic Plus adaptive cruise control. Common Affected Models

• Reduced power (turbo may be disabled completely)
• Poor fuel economy (15-20% worse)
• Risk of catalytic converter damage if mixture drifts too lean
