GODIAG GT115 MQB IMMO4 Test Platform for VAG Vehicles with POGO PIN to Read & Write Data

The GODIAG GT115 is a purpose-built off-vehicle test platform and connecting cable for V‑A‑G MQB vehicles (IMMO4). Designed for workshops and automotive engineers, it supports IMMO programming, key synchronization, diagnostics and secure read/write access to instrument cluster data using a stable POGO PIN interface.

Why choose the GT115?

• Compatible with MQB architecture (replacing PQ25/PQ35/PQ46)
• Off-vehicle IMMO programming, matching and diagnostics
• POGO PIN connection minimizes cable strain and prevents connector damage
• Real-time monitoring of voltages and currents for safer testing

Godiag GT115 Key Functions 

Synchronous Key and IMMO Module Detection

The GT115 performs synchronized detection of ignition keys and vehicle IMMO modules, enabling quick verification of pairing status and fault diagnosis.

Independent Engine & Power Expansion Module Diagnostics 

Run standalone diagnostics on engine and power expansion modules without full-vehicle wiring—ideal for bench testing and module repairs.

Gateway-Based Communication & Programming Tests 

Communicate and perform programming tests on engine and power modules via the vehicle gateway, including BCM interactions when required.

IMMO 4th Generation POGO PIN Read/Write & Key Sync

Read and write dashboard (instrument cluster) data through a reliable POGO PIN probe. Supports IMMO4 key synchronization and secure data operations for cluster repairs and cloning.

BCM and Gateway Module Testing

Connect BCM modules through the gateway for communication testing and programming. Some operations may require toggling the device’s dedicated switches.

Godiag GT115 Features

POGO PIN Technology for Dashboard Access

The integrated POGO PIN probe ensures stable contact with instrument cluster pads, reducing wear and eliminating cable stress. This enables accurate read/write operations for mileage, IMMO data, and configuration files.

Real-Time Power and Module Monitoring

• Displays current connected power supply voltage (V)
• Displays module current draw (A)
• Shows 2032 battery voltage to verify key/button battery health

Comprehensive Diagnostic Coverage

The GT115 supports:

• IMMO synchronization checks
• Engine and power module bench diagnostics
• Gateway and BCM communication checks and programming

How to Use the POGO PIN (Step-by-Step)

1. Ensure the power switch on the GT115 is OFF. 
2. Turn ON the vehicle IGN ignition power.
3. Connect the instrument plug to the GT115.
4. Locate the POGO PIN contact points on the instrument cluster and attach the probe.
5. Turn the GT115 power switch ON for 3–5 seconds. If the ABS light flashes, the device has entered POGO PIN read/write mode.

Safety note: Always follow ESD precautions and avoid powering modules improperly—incorrect connections can damage clusters or modules.

Typical Use Cases

• Off-vehicle instrument cluster repair and programming
• Key programming and IMMO synchronization for MQB vehicles
• BCM and gateway communication diagnostics for V‑A‑G platforms
• Bench testing of engine and power expansion modules
• Verification of key battery (2032) voltage and module current draw
