Target Vehicles and Core Function

The GODIAG GT114 cable connects Audi A4 and A6 C5 models from 2000 to 2006 to diagnostic tools for immobiliser work. It converts the dashboard connection to standard OBD2 so technicians can read and write instrument IMMO data, repair mileage and match keys offline.

Sustained Diagnostic Use

An independent power switch and separate ignition switch let the operator control voltage during long coding sessions without draining the vehicle battery. The key induction adapter includes a light to confirm coil activity while the tool maintains a stable K-Line link through extended data transfers.

Installation Notes

The package plugs into the dashboard harness and the tester with no soldering required. Successful key matching demands a genuine Megamos ID 48 key because the Xhorse super chip will not complete the process. After reading data the PIN code must be recorded and the generated IMMO file written back before learning can finish.

Questions about this item

Does the GT114 cable draw power from the car or need its own supply while running key-matching tests all day?

The cable has an independent power switch and an independent ignition switch, so it uses vehicle power but gives you manual control over when the dashboard and immobiliser circuits are energised.

Which diagnostic tools must I already own to use the GT114 for offline IMMO data reading and key synchronisation?

It works with HEX V2, VAGCOM VCDS 5053, VAS5054A, VAS6154, SUPER VAG K+CAN, Obdstar, Lonsdor, AVDI, ZEDFULL, VVDI2, Key Tool Plus, X300 DP Plus, SUPER VAG and AUTEL devices.

Can I keep using my existing Megamos ID 48 transponder keys when the GT114 writes new immobiliser data to the dashboard?

Yes — the matching process requires a Megamos ID 48 key, and after the instrument data is written back you perform the normal matching learning with those same keys.
