This Immobilizer OFF (IMMO OFF) service is designed for Volkswagen and select Audi vehicles equipped with MED9.X / MED9.1 ECUs. The service disables the factory immobilizer system inside the ECU, allowing the engine to run without immobilizer authorization. This is an ideal solution for vehicles experiencing immobilizer-related start-and-stall issues or when installing a used or replacement ECU.
This is a service-only listing. No ECU or vehicle parts are included.

Not sure if your ECU is MED9.X or MED9.1? Contact us with your ECU part number for confirmation.
Ship your MED9.X ECU to us.
We modify the ECU software to disable the immobilizer system.
Your ECU is returned ready to run, with no immobilizer authorization required.
This service is intended for vehicles that start and then shut down due to immobilizer activation.
Not recommended for vehicles that do not crank or do not start at all for non‑immobilizer reasons.
After IMMO OFF, the immobilizer warning light may remain illuminated on the dashboard.
This service does not repair hardware damage (water damage, burnt components, no communication ECUs).

What does Immobilizer OFF do?
It disables the factory immobilizer inside the ECU, allowing the engine to run without key or immobilizer authorization.
Will my car still start with my existing keys?
Yes. The engine will start normally, but the immobilizer system will no longer be active.
Will the immobilizer light stay on?
In some cases, yes. This is normal after IMMO OFF and does not affect drivability.
Is this legal for road use?
Immobilizer OFF is typically intended for off-road, race, export, or diagnostic purposes. Customers are responsible for compliance with local and state laws.
Do you fix non-starting ECUs?
Only if the issue is immobilizer-related. Hardware failures or no-communication ECUs require repair or cloning services.
Do you serve customers outside Texas?
Yes. We offer nationwide mail-in ECU services.
