GODIAG GT115 For V-A-G MQB IMMO4 CAN-Bus UDS 4th Generation IMMO System Test Platform with POGO PIN to Read & Write Data

This tool is a specialized diagnostic and programming test platform designed for V‑A‑G vehicles built on the MQB platform, especially those that use the 4th‑generation immobilizer (IMMO4) system. It’s essentially a connecting cable + test interface that lets technicians work off‑vehicle (bench testing) with various modules like the instrument cluster, BCM, gateway, engine modules, etc. It supports CAN‑Bus UDS communication used on newer MQB‑based cars.

The standout feature is a POGO PIN interface that allows stable reading and writing of data directly to/control of the dashboard/cluster without damaging fragile cable connectors.

Key Functions & Capabilities

According to official product documentation and manuals, the GT115 supports:

Core Test & Diagnostic Functions

• Synchronous key & IMMO module detection – detects presence and status of keys vs immobilizer modules.

• Independent diagnostics of engine and power expansion modules.

• Communication & programming tests between engine/power modules via the gateway.

• Real‑time monitoring of connected supply voltage and module current.

• 2032 coin battery voltage detection (common in instrument clusters).
