Report: BMW Scanner 1.4.0 Drivers

Part 6: Does the BMW Scanner 1.4.0 Work on Windows 11?

Yes, but with caveats. Windows 11 has stricter driver signing and memory integrity (HVCI). To run BMW Scanner 1.4.0 drivers on Windows 11:

  • You must disable Memory Integrity (Core Isolation) in Windows Security
  • Use the CH341 driver version 3.8 or newer for native Windows 11 compatibility
  • Run the PA Soft executable in Windows 7 compatibility mode (Properties > Compatibility tab)

Many users report success on Windows 11 22H2 and 23H2 after following the COM port restriction (COM1-4 only).

5. Installation Steps (General)

Compatibility

  • Most BMWs with OBD-II and earlier OBD protocols (pre-2005 E30/E36/E38/E39/E46 families).
  • Some late-model BMWs and newer protocols may not be supported; newer cars typically require ISTA/D or modern OBD-II tools.

1. Identify Your USB Adapter

The BMW Scanner 1.4.0 uses a USB-to-OBD cable with a BMW 20-pin round adapter (for older models) or just an OBD2 connector for E46/E39/E38/E53, etc.
Inside is an FTDI or CH340 USB serial chip. Most clones use CH340. bmw scanner 140 drivers

3. Installation Instructions (Windows 10/11)

Step A: Install the Software First Do not plug in the cable yet. Run the BMW Scanner 1.4.0 setup executable. When it asks to install the driver, you can let it try, but it often fails on Windows 10/11. Just finish the software installation.

Step B: Force the Driver Update

  1. Plug your BMW Scanner cable into the computer.
  2. Open the Device Manager (Right-click the Start button > Device Manager).
  3. Look under "Other Devices." You should see a device named "USB" or "BMW Scanner" with a yellow exclamation mark.
  4. Right-click the device and select Update driver.
  5. Select Browse my computer for drivers.
  6. Select Let me pick from a list of available drivers on my computer.
  7. This is the crucial step:
    • If you are using FTDI, look for USB Serial Port or USB Serial Converter.
    • If you are using CH340, look for USB-SERIAL CH340 (COMx).
  8. If the BMW Scanner software installed a driver previously, you might see "BMW Scanner Diagnostic Interface" in the list. You can try selecting that first. If that fails, try selecting the generic "USB Serial Port" option.

Step C: Set the Latency Timer (Critical for FTDI) If you have the FTDI (White) cable, the scanner will often fail to connect unless you change a specific setting:

  1. In Device Manager, find the cable under Ports (COM & LPT).
  2. Right-click it and select Properties.
  3. Go to the Port Settings tab.
  4. Click Advanced....
  5. Find the Latency Timer setting. It is usually set to 16.
  6. Change this to 1 or 2.
  7. Click OK and close Device Manager.

3. Compatible Operating Systems

| OS | Compatibility | Notes | |----|--------------|-------| | Windows XP | Full | Ideal, most stable | | Windows 7 (32/64-bit) | Good | May require legacy driver mode | | Windows 8/8.1 | Limited | Manual driver installation needed | | Windows 10 (32/64-bit) | Partial | Requires signed or test mode drivers | | Windows 11 | Unreliable | Not officially supported | Report: BMW Scanner 1

⚠️ 64-bit Windows requires driver signature enforcement to be disabled or use specially modified drivers.

7. Extra Tips

  • Do not update the driver via Windows Update – stick with the CH340 v3.5 or FTDI v2.12.
  • Some BMW Scanner 1.4 cables need external 12V power (rare) – most are powered by USB + car OBD.
  • If using a 20-pin round adapter under hood, ensure the cap is properly seated and ignition is ON (position 2).
  • Software works best on 32-bit Windows XP/7, but runs on 64-bit Windows 10 with compatibility settings.
