Step five: Access the MCU
Strip the casing from the instrument cluster, then disconnect ribbon and red plug connectors to lift the circuit board. Carefully remove the plastic trim and metal casing with a flat blade to expose the microprocessor. Identify the microprocessor type( in this case, D70F3526) to determine the correct ACDP connection procedure.
Step six: Read dashboard data
Connect the MQB adapter to the ACDP device following the on-screen diagram. Use the path: MQB IMMO → MQB 81 ICP → Read Dashboard. The device will decrypt the chip and save all instrument cluster data automatically.
Step seven: Obtain IMMO data and generate dealer key
Open the saved dashboard data and select‘ IMMO’. Confirm no external EEPROM is present. Calculate immobiliser data then insert the working key into the PCF adaptor. Select the saved IMMO data and continue. Next, remove the working key and insert the new AUTRK0079 key. Generate the dealer key and write key data.
Step eight: Reinstall instrument cluster
Carefully reconnect all connectors and secure the cluster back into the vehicle. Restore all trim and panels removed during disassembly.
Step nine: Program keys via OBD
With the instrument cluster reconnected, navigate to OBD Learn on the ACDP device. Insert the working key, turn ignition
on and select saved IMMO data. Next, follow prompts to learn all keys: number of keys was two. Insert each key in turn until the device confirms“ Keys learned: 2 / 2”.
Step 10: Test functionality Test central locking with both keys to ensure lock / unlock works, then start the vehicle with each key to confirm the engine starts successfully.
Outcome
During this procedure, a 2018 VW Golf GTE’ s virtual dashboard and immobiliser system were accessed using the ACDP device. The new AUTRK0079 key was generated as a dealer key, successfully programmed, and it now fully operates the vehicle for both locking / unlocking and starting.
