 In this guide, we will read and disable the immobilizer on a BMW F30 EDC17C50 ECU (Engine Control Unit) using the Xhorse Multi-Prog tool. This procedure is essential for tasks such as adding or making keys for BMW vehicles, as it involves extracting the ISN and modifying the ECU’s immobilizer settings.

Step-by-Step Procedure

1. Connecting the ECU

1. Identify the Connectors:

   • The ECU has two types of connectors: rectangular and circular. The circular connectors are used for transmission control modules, while the rectangular ones are for ECU communication.

2. Connect the Power Leads:

   • Attach the negative (ground) lead to pin number 2.

   • Connect the positive lead to the appropriate pin.

3. Attach Communication Wires:

   • Connect the remaining wires (red, blue, purple, gray, yellow, and green) to their respective pins as shown in the pinout. Ensure all connections are secure to avoid communication errors.

4. Secure the ECU Adapter:

   • Attach the ECU adapter to the back of the ECU and screw it in place.

2. Reading the ECU Data

1. Power On the Multi-Prog Tool:

   • Turn on the Multi-Prog tool and ensure the ECU is properly connected.

2. Read the Internal EPROM:

   • Select the internal EPROM option and click Read. This process takes approximately 4 minutes and 16 seconds.

Save the read file, which contains critical data such as the VIN and ISN.

Read the Internal Flash:

• • Next, read the internal flash, which takes longer (around 7 minutes). Save this file as well.

3. IMMO OFF with Multi Prog

Load the Saved File:

• • Navigate to the Tool tab- Turn Off IMMO option in the software and load the saved EPROM file.

Generate the Immobilizer-Off File:

• • Confirm the action to generate the modified file with the immobilizer disabled. Save IMMO OFF file.

Write the Modified File to the ECU:

• • Select the IMMO Off file and write it back to the ECU. The process involves sending and receiving data, accompanied by clicking sounds indicating communication.

Verify the Write Operation:

• • After writing, read the ECU again and compare the data with the IMMO Off file. Ensure the files are identical to confirm the immobilizer has been successfully disabled.

Final Notes

• Bench Mode: The entire procedure is performed in bench mode, meaning the ECU is not installed in the vehicle.

• Time Management: Reading and writing processes may take several minutes, so patience is key.

• Verification: Always compare files before and after writing to confirm successful modifications.

With practice, this process becomes straightforward, enabling efficient ECU management for BMW vehicles.

 Problem:

Tried to program 2022 Nissan Sentra B18 smart key with xhorse vvdi key tool plus. It asks for a 32-digit rolling code.

Where can I get the pin code?

Solution:

Key tool plus cannot pull pin code for Sentra B18.

Need to remove HFM hands free module and read pin from dump.

Xhorse multi prog will read HFM data, but key tool plus cannot decode pin code automatically.

Need to send data to xhorse engineer to decode pin code manually.

 Choosing the right key cutting machine is crucial for locksmiths, whether you’re a mobile professional or shop-based. Two top-tier options are the Xhorse Dolphin XP005L (Dolphin II) and the CGDI Godzilla. Here’s a detailed comparison to help you decide which one suits your needs.

Dolphin II vs. CGDI Godzilla Comparison

1. Unbeatable Portability

The Dolphin II is designed for locksmiths on the move. Its compact, lightweight build and built-in rechargeable battery allow you to take it anywhere – whether you’re servicing cars, homes, or businesses on-site. No need for a constant power source like the Godzilla, which ties you to a shop.

2. Advanced Touchscreen & Wireless Connectivity

• 5-inch adjustable touchscreen for effortless operation.
• Bluetooth & Wi-Fi support for seamless software updates via the Xhorse app.
• Over-the-air updates ensure your machine always has the latest features and key compatibility.

The Godzilla lacks wireless capabilities, meaning manual updates and fewer tech-forward advantages.

3. Superior Clamp System & Key Compatibility

The M5 Clamp on the Dolphin II handles a wider variety of keys with precision, including high-security and automotive keys. While the Godzilla can cut standard keys well, it doesn’t match the Dolphin’s adaptability for modern locksmithing needs.

4. Future-Proof Investment

With regular software upgrades, the Dolphin II evolves with industry trends, ensuring long-term usability. The Godzilla, while cheaper upfront, may require costly replacements or upgrades sooner.

Godzilla: A Good Machine, But Not the Best

The CGDI Godzilla is a budget-friendly, durable option for shop-based locksmiths, but it lacks:
– Portability (no battery, requires constant power)
– Wireless features (no Bluetooth or Wi-Fi)
– Latest tech advancements (manual updates, no touchscreen.

Conclusion: The Dolphin II Wins

CGDI Godzilla is ideal forLocksmiths who prioritize durability and affordability for a fixed workstation.

If you want a high-performance, portable, and future-proof key cutting machine, the Xhorse Dolphin XP005L is the clear winner. It’s the best choice for locksmiths who value mobility, efficiency, and staying ahead of the competition.
