Description

2011 Mercedes-Benz SL-Class 5.5L ECM / ECU – VIN Programmed | Plug & Play

This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2011 Mercedes-Benz SL-Class 5.5L models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with no dealer visit required.

Built to OEM standards for reliability, calibration accuracy, and long-term performance.

Strict Testing & Quality Assurance

Every ECU is inspected, refreshed, and verified through advanced diagnostic tools. Testing includes:

• Complete communication & CAN-bus verification

• Sensor input/output and signal integrity checks

• Injector & ignition pulse simulation

• Power, ground, and load-circuit analysis

• Flash memory integrity and checksum validation

• Thermal and voltage-stress testing to confirm reliability

This ensures a fully functional, reliable, plug-and-play module you can install with confidence.

Important Note

Some vehicles equipped with IMMO (Immobilizer) or PATS (Passive Anti-Theft System) may require additional key programming after installation. This is normal for models where security data must be synchronized with the vehicle’s body control system.

For a 100% plug-and-play solution with no relearns, no key programming, and no compatibility issues, we recommend our ECU Cloning Service, which transfers all original security, immobilizer, and configuration data directly into the replacement unit.
