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
