I’ve used the Xhorse BCM2 Encrypted Solder-Free Adapter for multiple BCM2 projects, and it’s a convenient solution for encrypted BCM2 read/write work on Volkswagen, Audi, Porsche, and Lamborghini. The adapter provides a clean, solder-free bench setup and is compatible with both Xhorse Multi-PROG and VVDI Key Tool Plus, making BCM2 programming more efficient and straightforward.
Who Is It For?
A great choice for:
- Technicians who frequently handle VAG BCM2 modules.
- Locksmiths looking for reliable BCM2 bench read/write capabilities.
- Workshops that want a convenient, solder-free connection solution.
Consider other options if:
- You only work on BCM2 modules occasionally.
- You are new to BCM2 bench programming.
- Your work does not require BCM2 reading or writing.
Real Workshop Notes: The Adapter Setup
The setup is straightforward once you identify the correct BCM2 version. The adapter fits securely onto the designated points and holds firmly during the job. The kit includes two adapter boards and two cables to cover different BCM2 versions. Best of all, the whole process is solder-free, making the connection quick and convenient.
Reading
I normally start with a Read ID to confirm that the CPU is detected correctly. Once the chip is recognized without any issues, I proceed with D Flash and P Flash.
The D Flash read is fairly quick, while P Flash takes a bit longer. In my testing, however, the overall reading process was stable and reliable.
One Thing to Keep in Mind
The BCM2 has to be unlocked again every time you perform a new operation. The unlock does not remain active after the initial decryption.
This can add a little extra time, especially when handling multiple operations. I wouldn’t recommend permanently unlocking the BCM2 just to save time, as doing so requires erasing the data.
Overall
Once the appropriate adapter and protocol are selected, the process is simple and efficient. The writing procedure follows essentially the same steps as the reading process.
What I Liked
- Secure connection: The adapter fits firmly onto the BCM2 connection points.
- No soldering required: Makes the setup cleaner and easier without soldering directly to the PCB.
- Flexible setups: Supports two different BCM2 configurations.
- ID reading: Lets you verify the connection before starting the full data-reading process.
- Multi PROG & Key Tool Plus compatibility: Great flexibility for users already working with either platform.
What Could Be Improved
- Repeated unlocking: Each unlocking step adds extra time to the overall process.
- P Flash speed: Reading larger amounts of data can take noticeably longer.
- Accurate identification is essential: The BCM2 version, CPU type, and communication protocol must all be correctly matched.
- Some bench experience is recommended: The process is not entirely plug-and-play, especially for beginners working with BCM2 modules.
Would I Buy It Again?
Yes. After using it on several BCM2 jobs, I’d definitely keep it in my bench setup. The solder-free adapter has been reliable, convenient, and easy to use once the correct wiring and configuration are confirmed. The need to repeat the unlock process is something to keep in mind, but overall, it hasn’t been a major issue and hasn’t changed my opinion of the adapter.
