Comprehensive Guide to BMW Scanner 1.4.0 Drivers BMW Scanner 1.4.0 (often referred to as PA Soft) is a popular diagnostic tool for older BMW models, including the E38 (7 series), E39 (5 series), and E46 (3 series). While powerful for reading error codes, checking mileage discrepancies, and customizing car features (coding), it is notorious for driver installation difficulties on modern operating systems like Windows 10 and 11. Core Functionality
Module Scanning: Identifies chassis, model, engine, and gearbox data across all communicable modules.
Error Management: Reads and erases Diagnostic Trouble Codes (DTCs) from modules like the DME, EWS, and IKE.
Feature Coding: Allows users to enable features such as auto door locks, window roll-up/down via the key fob, and more through the ZKE module.
Data Verification: Compares odometer values in different modules to detect potential tampering. Driver Installation for Windows 10/11
Modern versions of Windows require digitally signed drivers by default, which the original BMW Scanner drivers lack. There are two main ways to overcome this: Option 1: Disabling Driver Signature Enforcement
This is the most common method for getting the scanner to work on 64-bit systems.
Getting Your BMW Scanner 1.4.0 (PA Soft) Running on Windows 10/11
If you’ve recently picked up a BMW Scanner 1.4.0 (often called "the Bobcat" or "PA Soft"), you’ve likely realized the included disc is basically a coaster. Getting the drivers to play nice with modern 64-bit versions of Windows is the biggest hurdle, but it is entirely doable with a few manual steps. 1. The Driver Dilemma The scanner uses an
to communicate via USB. Modern Windows versions often automatically install the latest FTDI drivers, which unfortunately can "brick" or ignore the older clones used in many cheap BMW scanners. You need the specific x64 D2XX drivers . Many enthusiasts recommend using the FTDI Chip D2XX Drivers
directly or finding the "patched" version common on forums like Bimmerforums 2. Bypass Driver Signature Enforcement
Windows 10 and 11 won't let you install "unverified" drivers by default. You have to temporarily lower the gates: Method A (CMD): Run Command Prompt as Admin and type: bcdedit /set testsigning on , then restart your PC. Method B (Advanced Startup):
Go to Settings > Recovery > Advanced Startup. Upon restart, choose
Troubleshoot > Advanced options > Startup Settings > Restart to "Disable driver signature enforcement". 3. Manual Installation (The Critical Step)
Don't use the "Setup.exe" that comes with the software. You must do this through Device Manager
Plug the scanner into your PC (it doesn't need to be in the car yet). Device Manager
. Look for "BMW Scanner" or "Unknown Device" with a yellow exclamation mark. Right-click it and select Update Driver Browse my computer for drivers bmw scanner 140 drivers
Point it to the folder where you extracted the 64-bit drivers.
If it still fails, select "Let me pick from a list," click "Have Disk," and manually select the file from your driver folder. 4. Avoiding the "Hardware Faulty" Error
The most common mistake is trying to run the software while the scanner is only plugged into your laptop. Connect to the Car First:
You must plug the scanner into the car's OBDII port (or the 20-pin under-hood port for older models) and turn the ignition to position 2 before opening the software.
If you get a "Hardware Faulty" message, the software isn't seeing the 12V power from the car. 5. Final Hardware Tweaks
Many of these scanners require a small physical modification to work with certain models (like the E46 or E39). If you can only see a few modules (like DME or EWS) but others are red/missing, you likely need to solder pins 7 and 8 together
inside the scanner plug. This bridges the two K-lines required to read all the car's modules. Was this guide easy to follow? Installation steps Driver links
BMW scanner 1.4 installation tutorial for Windows 10. (PA Soft)
Installing drivers for the BMW Scanner 1.4.0 (often called PA Soft) can be tricky on modern 64-bit systems like Windows 10 or 11. Most issues stem from the fact that the original drivers were intended for 32-bit Windows XP. Essential Installation Steps To get the scanner working correctly, follow this sequence:
Download 64-Bit Drivers: Standard discs often only include 32-bit drivers. You typically need to download the D2XX drivers directly from the FTDI Chip Drivers Page.
Plug-In Sequence: Plug the scanner into the car's OBD port first to power it (look for a solid green light), and then connect the USB to your computer.
Manual Update: Open Device Manager, find the "BMW Scanner" device (it will likely have a yellow exclamation mark), right-click it, and select "Update Driver".
Disable Driver Signature Enforcement: On Windows 10/11, you may need to disable "test signing" or driver signature enforcement to allow the unofficial drivers to load. Use the command prompt as an admin and run bcdedit /set testsigning on, then restart your PC. Common Error Fixes
"Connection Error with IKE/EWS": If the software opens but won't talk to the car, you might need to solder pins 7 and 8 together inside the scanner cable, as some aftermarket cables come with these disconnected.
"Access Violation": This often happens if you try to run the software before the drivers are fully recognized by Windows.
64-Bit Compatibility: If you're on a 64-bit system, ensure you specifically point the Device Manager to the folder containing the ftdibus.inf and ftdiport.inf files. Where to Find Help Comprehensive Guide to BMW Scanner 1
The BMW Scanner 1.4.0 (often called PA Soft) is a versatile diagnostic tool for older BMW models like the E38, E39, E46, E53, E83, and E85. While highly capable for reading codes and customizing features, its biggest hurdle is driver installation on modern 64-bit versions of Windows (10/11) due to strict driver signature requirements. Core Installation Steps
To successfully set up the scanner, you must bypass Windows' security features and manually point the system to the correct 64-bit drivers.
