2. Supported Key Functions & Features
The GODIAG GT114 supports multiple Audi immobilizer testing and key matching functions.
Offline Dashboard Connection
• Connects directly to the immobilizer dashboard
• Converts dashboard communication into a standard OBD2 interface
• Allows offline IMMO testing without installing the dashboard in the vehicle
Key Chip and Instrument Synchronization Test
• Tests key chip communication with the immobilizer system
• Performs instrument synchronization testing
• Helps verify whether key matching conditions are available
IMMO Dashboard Diagnosis
• Supports offline immobilizer dashboard diagnosis
• Reads and writes supported IMMO instrument data
• Helps technicians analyze immobilizer system problems
Key Matching Function
Supports:
• Key chip matching preparation
• Instrument IMMO synchronization
• Immobilizer data processing
Note:
Audi A6 C5 key matching requires a compatible Megamos ID48 key chip. Xhorse Super Chip cannot be successfully matched in this process.
Instrument Mileage Repair
• Supports mileage data repair functions on compatible Audi IMMO dashboards
Intelligent IMMO Emergency Start Area Detection
• Detects the vehicle key emergency start sensing area
• Helps identify the backup start location when the smart key battery is low or empty
IMMO Start and Key Chip Detection
The key identifier indicator provides test results:
• Light flashes and then turns off: IMMO chip and key are working normally
• Light flashes continuously: Key chip and vehicle IMMO system are not matched and require re-learning
• Light does not flash: Possible vehicle IMMO system fault
Independent Switch Design
• Independent power switch
• Independent ignition switch
• Key induction adapter with indicator light
