This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2009 BMW 335i 3.0L AT gas 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.

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 require key programming after installation. This is normal.
For a 100% plug-and-play solution, we recommend using our full cloning service. We transfer all security data to the replacement unit.

If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I was really impressed with how smoothly the whole process went. The ECU arrived quickly with free shipping, which was a nice surprise. It was already VIN programmed, so installation was a breeze—just plug and play. The car started right up, and performance feels flawless now. The sellers also kept me in the loop throughout the entire shipping and programming stages, which gave me a lot of confidence in their service. Highly recommend!
