2011 Audi A6 4.2L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2011 Audi A6 4.2L 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 swapping out the ECU on my 2011 Audi A6, but this unit made the process incredibly smooth. It arrived quickly, well-packaged, and was already programmed to my VIN, so there was no hassle with additional coding. Installation was truly plug-and-play—everything fit perfectly, and my car fired up without a single issue. After a few days of driving, I can say the performance feels just as crisp as before, maybe even better. Great product and excellent support from the seller when I had a quick question. Highly recommend for anyone needing a reliable ECM replacement!

The VIN programmed ECM arrived quickly and was exactly as described for my 2011 Audi A6 4.2L. Installation was straightforward, truly a plug-and-play unit with no extra programming needed on my end. After swapping it out, the car fired up immediately and runs perfectly, making this a hassle-free solution. The support team was also very responsive when I had a couple of questions before ordering.
