Professional laboratory board-level overhaul service
If your component exhibits any of the following issues, this specific laboratory repair will permanently resolve them. We do not just replace components that are currently failed; we re-engineer known wear points site-wide:

Cycling from -20°F to 180°F
End-to-end active network testing
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).
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.
Audi A4 (B5, B6) 1.8T: 1999–2006
Audi S4 (B5) 2.7T: 1999–2002
Audi TT (1.8T): 1999–2006
Audi A6 (C5) 2.7T, 3.0 V6: 1999–2004 * (Alarm and hazard lights may flash after starting)
Audi Allroad 2.7T: 2001–2005
If your vehicle isn’t listed, send us your ECU part number for verification.
Q: Will this service work if my Audi won’t start at all?
A: No. This service only bypasses immobilizer interference; the engine must be able to start for it to be effective.
Q: Will the immobilizer light or alarm behave differently after service?
A: On some models, particularly A6 ECUs starting with 8E0, the immobilizer light may stay on and alarm/hazard lights may flash briefly after starting. This is normal.
Q: Can I use this service on a replacement or used ECU?
A: Yes. This service is ideal for installing a used or remanufactured ECU without immobilizer-related start issues.
Q: Do I need to clear OBD codes?
A: Yes. Clear any existing OBD codes before or after the service for proper ECU operation.
Q: My Audi model isn’t listed. Can this service still work?
A: Send us your ECU part number for verification. We’ll confirm compatibility.
