2012 BMW 5 Series 4.4L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2012 BMW 5 Series 4.4L 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.

I was a bit nervous about replacing the ECM on my 2012 BMW 5 Series, but this unit arrived exactly as described and was ready to go right out of the box. The VIN was already programmed, which saved me the hassle of dealing with complicated coding. Installation was straightforward, and my car fired up without any issues the first time. Shipping was surprisingly quick, too, so my weekend plans didn’t get delayed. Overall, a hassle-free experience that I’d recommend to anyone needing a reliable ECM replacement.
Swapping out the ECU on my BMW was something I thought would require dealer intervention, but this product completely changed that. It arrived well-packaged and was pre-programmed to my VIN, making the switch super simple. The engine runs smoother now, and the check engine light is gone, which was a huge relief. If you want an easy fix without the dealership price, this is the way to go. Plus, the support team was very responsive when I had a quick question
