Description
2011 Mercedes-Benz E-Class 5.5L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2011 Mercedes-Benz E-Class 5.5L models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with our cloning service.
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
Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

Samuel Sanders –
Installed this ECM in no time, and my E-Class runs like new again—couldn’t be happier with the quick delivery and seamless fit.
Perfect match for my 2011 E-Class, arrived fast and worked immediately without any fuss.
This ECU was exactly as described, made the install process straightforward and got my car back on the road quickly.
Super smooth experience from order to install, the VIN programming was spot-on and had my Mercedes purring perfectly.
Arrived faster than expected and plugged right in—definitely a stress-free upgrade for my E-Class!
