Mercedes-Benz W218 CLS350 Engine Control Unit - Used Original Parts

Diagnosis and Common Symptoms

From a workshop perspective, a failing Motor Electronics (ME) control unit in the W218 CLS350 presents a distinct set of diagnostic challenges. Initial symptoms often manifest as intermittent engine hesitation or misfires under load, which can be mistakenly attributed to faulty ignition coils or injectors. A primary indicator of ECU failure is a no-start condition where the engine cranks but receives no spark or fuel injector pulse, despite all related sensors and wiring testing correctly.

Diagnostic scans will frequently reveal a loss of communication with the ME control unit or display fault codes pointing to an internal processor error.

Common Dashboard Errors & Symptoms:

• Check Engine Light (CEL) permanently illuminated
• Vehicle enters "Limp Mode" with drastically reduced power
• Engine cranks but will not start
• Severe and persistent cylinder misfires
• Complete loss of communication with the ECU via diagnostic tools

Relevant Fault Codes:

• P0606 - ECM/PCM Processor Fault
• P0607 - Control Module Performance
• U0100 - Lost Communication With ECM/PCM
• Multiple injector or ignition circuit codes (P02XX, P03XX) without a mechanical cause
