Replacing the Engine Control Module (ECM) or Powertrain Control Module (PCM) on a modern Mercedes S-Class is a highly complex task. The new unit must be correctly coded to the vehicle's immobiliser (DAS), VIN, and specification data before the engine will start. We perform this critical, dealer-level programming on-site.
- New Module Flashing: Programming virgin ECM/PCM units with the latest Mercedes software tailored to your VIN.
- Immobiliser Synchronization (DAS): Aligning the new engine control unit with the vehicle's Electronic Ignition Switch (EIS) and keys.
- SCN Coding (Simplified): Applying essential coding parameters to match the car's full factory specification and equipment.
- Post-Installation Diagnostics: Full scan and clearance of fault codes to ensure peak engine and security performance.
This service is essential after an ECM failure or major engine electrical repair. We cover the W222 Saloon, C217 Coupe, and A217 Cabriolet petrol models from 2014 to 2020.
