Bmw Error-d52c44 [new] Direct

D52C44 is a manufacturer-format diagnostic trouble code indicating a fault in the active steering control electronics. In BMW diagnostics this class of codes is usually logged by the steering control module (Active Steering ECU) when it detects internal errors, power/ground/communication faults, or inconsistent sensor/actuator data that compromise safe operation.

The EPS module is located low on the chassis and on the steering rack itself. Exposure to heavy rain, road salt, or deep puddles can force moisture into the wiring plugs, causing pin corrosion or temporary short circuits that block data flow. D52C44 and 210901 - 2010 2011 BMW 5 Series Forum F10
