How to Solve Xhorse Multi Prog Porsche XDNP17 BCM Adapter Chip Crack Failed Error

Problem:

Read Porsche BCM 1L15Y with Xhorse multi prog and XNDP17 Porsche BCM solder free adapter. Multiprog can’t decode CPU. Software reported error chip crack failed. Any suggestions?

Solution:

Clean the contacts on the pbc with ipa, or nail varnish.

Also do as the software says, adjust the VDD voltage to 4-5V.

Go to Operation tab- Voltage.

Some reported VDD 4.5V work without issue.

Use Godiag GT110 with Xhorse VVDI Key Tool Plus

The GT110 is one of a series of test platforms designed by Godiag to emulate the immobilizer systems of VAG (Volkswagen, Audi, Skoda, Seat) vehicles. Specifically, the Godiag GT110 is engineered for Generation 4 immobilizers.

The device itself is a compact box that serves as a surrogate for the car’s dashboard. Its key components include:

• An Ignition Ring (Coil): This acts as the vehicle’s transponder antenna, allowing the platform to read and write to key chips.
• A Transponder Slot: A dedicated place to insert a transponder chip separately if needed.
• Dashboard Connector: A specific cable (referred to as a “Pogo pin” connector) that plugs directly into the vehicle’s instrument cluster.
• Power and Ignition Controls: Buttons to simulate turning the platform’s power on/off and switching the ignition on/off.
• OBD-II and Power Ports: It features a port for a 12V power supply and an OBD-II connector for direct linking to a programmer like the Xhorse VVDI Key Plus or VVDI2.

Why Use a Test Platform?
These devices are essentially simulated ignition locks and immobilizer antennae. They allow a technician to:

• Work on the car’s instrument cluster on a bench, away from the vehicle.
• Service customers remotely. A client can ship their instrument cluster and door lock (for blade cutting) to the specialist, who then programs the key and returns everything by mail.
• Test and repair clusters efficiently without repeatedly going to the car.

The Primary Use Case: Remote Key Programming

The most significant advantage of the GT110 is the ability to perform key-related jobs remotely. Imagine a customer from 1,000 km away contacts you with a Golf VI and no keys. Instead of turning down the job or traveling, you can provide a solution:

Instruct the customer to remove and ship you two components: the driver’s door lock (to cut a new key blade) and the instrument cluster.

Using the GT110 on your bench, you can connect the customer’s instrument cluster to the platform.

You can then perform a full key-loss procedure—reading the EEPROM, generating a service mode dump, preparing dealer keys, and learning them into the immobilizer—all without the car being present.

Once done, you ship back the instrument cluster and the newly programmed key. The customer reinstalls them, and the car starts.

This capability dramatically expands your service area and makes previously impossible jobs highly feasible.

Key Features and Benefits of the GT110

Bench-Top Efficiency: Eliminates the need to constantly run back and forth to the car. All programming and testing are done in the comfort of your workshop.

Remote Business Enablement: Unlocks a new revenue stream by allowing you to service customers nationally or even internationally.

Diagnostic Capabilities: The platform allows you to check the immobilizer status, see how many keys are programmed, and verify if the system recognizes a transponder (the indicator light on the platform behaves like the car’s).

VAG Coverage: While the GT110 covers Gen 4, Godiag offers other platforms (GT11, GT112, GT114) for older generations (2 & 3), allowing a specialist to cover the entire VAG lineup.

Demonstrating the Test Platform

We demonstrate the GODIAG GT110 test platform. By connecting the instrument cluster and a power source to the platform, he was able to:

Power on the cluster independently.

Simulate ignition on/off cycles.

Read immobilizer status.

Successfully program additional keys to the cluster entirely on the workbench, proving its utility for remote jobs.

How to Cut PS AHU83 Key with Xhorse Dolphin XP005

 Problem:

When I tried to cut a Citroen Jumpy key with a HU83 blade in my Xhorse Dolphin XP005, I had this problem. It fit properly in the door lock, but not in the ignition cylinder. Afterwards, I looked at the detail in the attached photo. Could this be the reason why the key didn’t fit properly?

Solution:

The end of the key likely isn’t actually cut properly. If you held the original and new key up together they would be slightly different at the tips/last bitting. Use universal duplication to cut HU83 with extra bitting.
Other people with the same issue. So as long as the machine is calibrated right, it decoded it properly, and the key actually was HU83 and not VA2, then it will just be that same bug, it’s nothing you’ve done wrong apart from maybe not comparing the keys after you cut them.

We’ve experienced the same problem, and the issue lies not with the cut, but with the key not passing dust lid you need to file tip of the key narrow to pass it. Just done the same hu83 for 308 today, file tip a bit and it will work.
