The Mercedes-Benz fault code translates to "Communication with control unit 'Radar sensorics' has a malfunction"
Q: Can a bad MAP sensor cause U11A600 on an AMG? Absolutely. On the M177 (C63/E63), U11A600 is often linked to the bank 1 manifold pressure sensor. AMG engines have two sensors (one per bank). You must identify which bank logged the fault.
Anyone familiar with code U11A600 on their Mercedes?
Monitor the following live values while idling and under light acceleration:
Hypothetical Match: Components matching the U11A... series are frequently found inside:
Q: Will disconnecting the battery reset U11A600? Temporarily, yes. But the code will return once the ECU runs its monitoring cycle (usually a few drive cycles). Disconnecting the battery is not a fix.
