FAQ:

What is this service for?
This service disables the EWS immobilizer in the Bosch ME7.2 DME, allowing the vehicle to start without immobilizer synchronization.

Will I need dealer programming after this service?
No. Once the immobilizer is disabled, the DME is plug-and-play and does not require dealer or factory-level programming.

Do I need to send my DME to you?
Yes. The DME must be shipped to us so we can perform the immobilizer-off modification.

Does my replacement DME need to match part numbers?
Matching part numbers are strongly recommended for best compatibility, but immobilizer removal eliminates EWS matching requirements.

Will this trigger a check engine light?
No. While an immobilizer-related fault code may be present, it will not trigger the check engine light.

How long does the service take?
Most services are completed within 1–2 business days once the DME is received.

Who pays for shipping?
You are responsible for shipping the unit to us. We cover return shipping back to you.
