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.
