00-06 AUDI ME7.X Immobilizer Delete Service - IMMO OFF
This service is designed for Audi vehicles equipped with Bosch ME7.1, ME7.1.1, and ME7.5 ECUs. It bypasses the immobilizer system in the engine control unit (ECU), allowing your vehicle to run without immobilizer interference. This service is ideal when replacing a faulty ECU with a used unit or resolving immobilizer-related starting/shutting down faults.
Common fault codes addressed: P1570 (Engine start blocked by immobilizer), P0513 (Incorrect immobilizer key).
Important Notes
-
If your vehicle won’t start at all, this service will not be effective.
-
For Audi ECUs with part numbers starting with 8E0, bypassing the immobilizer allows the engine to run, but the alarm and hazard lights may flash briefly after starting (common with Audi A6 models).
-
After service, the immobilizer light may remain illuminated depending on the fault.
-
Clear all OBD codes before or after the service for proper operation.
