GODIAG GT114 Audi K-Lline IMMO
The GODIAG GT114 Audi K-Lline IMMO is a professional test platform cable designed for Audi A4 and A6 C5 2nd and 3rd generation dashboards. This advanced diagnostic cable allows technicians to perform offline IMMO key matching, dashboard synchronization, data reading and writing, mileage repair, and IMMO testing. It is a reliable tool for automotive locksmiths and ECU repair specialists who work with Audi IMMO systems.
It supports Audi A6 C5 vehicles from 2000 to 2006 and is compatible with diagnostic devices such as VXDIAG VCX SE 6154, VCX NANO 6154, and other VXDIAG VCX tools with VW licenses. With this cable, users can perform key learning, IMMO activation tests, and system diagnosis without connecting to the vehicle directly.




1. Use a Megamos ID 48 key for matching. Xhorse super chips are not supported. Generated IMMO data must be written back to the dashboard, followed by learning procedures.
2. Always note the PIN code after reading data — it’s needed during the key matching process. The ignition signal must be clear; otherwise, matching may fail. Follow on-screen instructions carefully, including required waiting times.

When pressing the vehicle’s start button, bring the key identifier close to specific areas. If the light on the key identifier flashes or stays on, that area is the vehicle’s key emergency start sensing zone. If the key battery is dead, placing it in this area allows the vehicle to start.
