Xhorse Audi BCM2 Adapter V2 Review

I’ve used the Xhorse BCM2 Encrypted Solder-Free Adapter on several BCM2 jobs. It’s a practical bench setup for encrypted BCM2 read/write work on Volkswagen, Audi, Porsche, and Lamborghini, and it works with both Multi-PROG and VVDI Key Tool Plus.

Who Should Buy It?

Good fit for:

• Technicians regularly working on VAG BCM2 modules.
• Locksmiths who need BCM2 bench read/write capability.
• Workshops that prefer solder-free connections.

Not the best fit for:

• Shops that only see BCM2 occasionally.
• Beginners with no BCM2 bench experience.
• Technicians who don’t need BCM2 read/write work.

Real Workshop Notes

The Connection

The connection is pretty simple once you have the right BCM2 version. The adapter locks onto the required points and stays in place well.

The kit has two adapter boards and two cables for different BCM2 versions. I like the setup because there’s no soldering involved.

Reading

I usually do a Read ID first. If the CPU is recognized correctly, I move on to D Flash and P Flash.

D Flash is relatively quick. P Flash takes longer, but the actual reading process was stable in my testing.

One Thing to Expect

The BCM2 needs to be unlocked again for each operation. It doesn’t stay unlocked after the first decryption.

That adds some time, especially if you’re doing several operations. I wouldn’t permanently unlock it just for convenience because that means erasing the data.

Overall

Once the correct adapter and protocol are selected, the workflow is straightforward. Writing follows basically the same approach as reading.

What I Liked

1. Stable fit: The adapter stays firmly on the BCM2 connection points.
2. Solder-free: No direct soldering to the board.
3. Two setups: Covers different BCM2 versions.
4. Read ID: Useful for checking the connection before a full read.
5. MultiPROG&Key Tool Plus: Good flexibility if you already use either platform.

What Could Be Better

1. Repeated unlocking: Adds extra time between operations.
2. P Flash speed: Larger data takes noticeably longer to read.
3. Correct identification is important: The BCM2 version, CPU, and protocol all need to match.
4. Some bench experience helps: It’s not completely plug-and-play for someone new to BCM2 work.

Would I Buy It Again?

Yes. After using it on multiple BCM2 jobs, I’m comfortable keeping it in the bench setup. The BCM2Solder-Free Adapteris stable, solder-free, and easy to work with once the correct configuration is identified. The repeated unlock step is the main thing to account for, but it hasn’t been enough to put me off using it.

VVDI2 and Multi Prog Change VAG MQB 5A Cluster Mileage

 Xhorse Multi Prog and VVDI2 are possible to change the odometer for VAG MQB 5A cluster. You can read it for immo.

Besides being able to make lost keys (Read micro v850 and rh8505a), Odometer also works.

Example:

Mileage change rh850 5a
With multiprog.
Everything ok.

Original mileage 52,216 km

Desired mileage: 890km
