Description
2008 Audi A4 3.1L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2008 Audi A4 3.1L 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 really impressed with how straightforward this ECM was to install on my 2008 Audi A4. Since it came already programmed to my VIN, I just plugged it in and everything fired right up without any hiccups. The shipping was surprisingly fast, which helped me get my car back on the road sooner than I expected. I appreciate that the seller had tech support available in case I ran into any issues, though thankfully I didn’t need it. Overall, this was a smooth, hassle-free experience and the car is running great now. Would definitely recommend to anyone needing a replacement ECU.
