New VCI+A-BT (also known as the "New VCI" or "Multidiag Pro+") is a popular aftermarket vehicle communication interface used for automotive diagnostics. Finding the correct drivers and software is crucial for establishing a stable connection between your PC and the vehicle's OBD-II port. 1. Understanding the Hardware The New VCI+A-BT typically uses a single board double board
design and relies on a USB-to-Serial bridge to communicate with your computer. : Most versions use the Silicon Labs CP210x USB to UART bridge. Capabilities
: It supports both USB and Bluetooth (BT) connectivity for diagnostic software like Silicon Labs 2. Where to Download Drivers
Because these devices are often third-party or generic, official manufacturer websites are rare. However, reliable packages exist: Delphi VCI Driver Package
: This is a standard set of drivers that enables Windows to recognize VCI hardware for automotive diagnostics. You can often find these through software update portals like Software Informer VCI (Diagnostic Unit) Drivers : Repository sites like Driver Scape
host drivers specifically for the VCI Diagnostic Unit, supporting Windows XP through Windows 10. 3. Installation Steps Connect the Device : Plug the VCI into your computer via USB. Check Device Manager
: Open Device Manager on your PC. If the device appears as "Unknown Device" or "USB Serial Port" with a yellow exclamation mark, the driver is missing. Update Driver
: Right-click the device in Device Manager and select "Update Driver." Point the wizard to the folder where you downloaded the VCI or Delphi driver package. Pairing Bluetooth
: For the "BT" functionality, you must pair the device through your Windows Bluetooth settings. The default pairing code is usually 4. Common Software Integration The New VCI+A-BT is most commonly used with Autocom 2021.11
or similar versions, which provide a comprehensive interface for reading fault codes and live data. When installing the software, ensure the firmware on the VCI matches the software version to avoid communication errors. CP210x USB to UART Bridge VCP Drivers - Silicon Labs

The New VCI-A-BT driver is a essential component for the Xentry VCI (Vehicle Communication Interface), which is used for Mercedes-Benz vehicle diagnostics. This driver enables the hardware to communicate with diagnostic software like Xentry/DAS, particularly over Bluetooth (as indicated by the "BT" in the name). Key Features and Functionality
Wireless Connectivity: It provides the necessary protocols for secure Bluetooth pairing between the VCI device and your diagnostic laptop, allowing you to perform scans without being physically tethered to the car.
Hardware Initialization: The driver allows the Windows operating system to recognize the Xentry VCI hardware, ensuring that the "VCI-A" (the specific hardware revision) is correctly identified.
Data Translation: It acts as a bridge, translating the high-level diagnostic commands from the software into low-level signals that the vehicle's electronic control units (ECUs) can understand.
Firmware Compatibility: Modern versions of the driver often include update utilities that ensure the VCI's internal firmware is compatible with the latest version of Xentry software. How to Download and Install
Source: These drivers are typically bundled with the Xentry OpenShell or Xentry PassThru installation packages. If you are using a legitimate workshop setup, the "VCI Manager" or "ConfigAssist" tool will handle the driver installation automatically.
Manual Installation: If the driver is missing, it can usually be found in the installation directory of your diagnostic software: C:\Program Files (x86)\Mercedes-Benz\Xentry\VCI.
Third-Party Tools: For users with cloned or aftermarket hardware, the driver is often provided by the vendor via a dedicated download link or an included USB drive, as standard Mercedes-Benz drivers may sometimes require specific patches to work with non-OEM hardware.
Once you have located the New VCI-A-BT driver download, follow these steps to ensure a clean installation: New Vci-a-bt Driver Download
Step 1: Disconnect the Device Do not plug the VCI-A-BT into your computer yet. If it is already plugged in, unplug it.
Step 2: Run the Installer as Administrator Locate the downloaded file (usually a .zip or .exe). Extract it if necessary. Right-click the installer file and select "Run as Administrator." This is crucial; standard permissions often block the writing of registry keys needed for the driver.
Step 3: Follow the Wizard The installation wizard will guide you through the process. If prompted with a Windows Security warning saying "Windows can't verify the publisher of this driver software," click "Install this driver software anyway." This is common with automotive hardware that uses generic chipsets.
Step 4: Connect and Verify Once the installation is complete, plug in your VCI-A-BT via USB or connect via Bluetooth. Open Device Manager and expand the section labeled "Ports (COM & LPT)" or "Universal Serial Bus controllers." You should see the VCI-A-BT listed without a yellow exclamation mark.
Do not download from “driver download .com” sites. Use these legitimate sources:
| Source | Reliability | Notes | |--------|-------------|-------| | Official Manufacturer Website | Highest | Check your device’s brand (e.g., VXDIAG, VCX NANO, or generic B&T). | | Microsoft Update Catalog | High | Search for “VCI Bluetooth” or “J2534 driver”. | | Techstream DVD Package | Medium | The driver often comes bundled with Toyota Techstream 12.x or newer. | | GitHub (Open Source Drivers) | Medium-High | For advanced users; look for “libusb” or “Zadig” drivers. |
Direct Download Suggestion: If you have a generic VCI-A-BT, the most common stable driver is the Silicon Labs CP210x Universal Windows Driver (version 11.2.0 or higher). Google “Silicon Labs CP210x VCP” and go to the official Silicon Labs site.
If you purchased a third-party clone (common on eBay or AliExpress), you cannot use official DrewTech drivers. Instead:
However, be aware that clone drivers are often unsigned and may trigger antivirus warnings. Proceed at your own risk.
A: Yes. The USB driver is required initially to flash the Bluetooth firmware and set up the serial COM mapping. After that, the Bluetooth connection uses the same driver architecture.
Navigate to the official support website of the device manufacturer. Do not use third-party "driver downloader" tools, as these often bundle bloatware.
