Vcds Loader - Kolimer Failed 2
If you are using a cheap eBay cable (FTDI chip with spoofed EEPROM), the loader might fail because the cable’s firmware is corrupted. Use MProg or FT_Prog to re-flash the cable with a generic FTDI configuration. This is an advanced procedure.
You installed ODIS, ELSAD, or a different VCDS crack. Now Kolimer fails.
Likely cause: Another tool installed a system-wide hook, driver conflict, or modified the hosts file.
Even with Real-time protection off, it's best to whitelist the folder.
The error "VCDS Loader Failed 2" typically indicates a communication or security conflict between the third-party Kolimer loader and the VCDS software, often occurring when the interface firmware and software versions become mismatched. This error is common for users of non-genuine HEX-V2 or ATMEGA-based cables that rely on a custom loader to bypass official license checks. Root Causes
Version Mismatch: The VCDS software may have been updated (automatically or manually) to a version that the current Kolimer loader does not support.
Antivirus Interference: Security software often flags third-party loaders like Kolimer as a "false positive," deleting or blocking essential files during execution.
Driver Conflict: Windows may have automatically updated the USB drivers to an official Ross-Tech version that is incompatible with the loader's requirements.
Bricked Interface: If the cable was connected to the internet while official VCDS software was running, the firmware might have been "soft-bricked" or locked by the official server. Troubleshooting & Fixes Disable Antivirus/Windows Defender:
Temporarily disable real-time protection and add the VCDS installation folder (usually C:\Ross-Tech\VCDS) to your exclusion list. Clean Reinstall:
Uninstall the current VCDS software and drivers through the Windows Apps/Programs menu.
In Device Manager, find the "Ross-Tech" device, right-click, and select "Uninstall device," ensuring you check the box to "Delete the driver software for this device".
Reinstall the specific version of VCDS provided with your cable and the corresponding Kolimer loader. Manual Driver Installation:
If the interface is not found, manually point the device driver update path to the VCDS installation folder (C:\Ross-Tech\VCDS\). Force Firmware Reset:
For interfaces stuck in a "failed" state, some users use the VCI Config utility (accessible via the "Net" or "Config" button in VCDS options) to force a firmware re-check or update, though this carries a risk of permanently bricking clone cables. Disable Core Isolation:
On Windows 10/11, disable "Memory Integrity" under Core Isolation in Windows Security, as it can block the older drivers used by custom loaders. Version Compatibility Note
Atmega-based cables generally support features up to version 19.x, even if they appear to work with newer versions like 25.x. If you have a newer vehicle, these older clones may fail to communicate with certain modules.
The "VCDS Loader Kolimer Failed 2" error typically occurs when using non-genuine or "clone" HEX-V2 interfaces with the VCDS software. This error often indicates that the loader cannot properly communicate with the interface hardware or that the software environment is blocking its execution.

"Failed 2" error in the Kolimer VCDS loader typically indicates a communication breakdown between the loader software and the diagnostic cable's hardware, often caused by an anti-virus deletion firmware mismatch
. This is common with "clone" interfaces when the software detects unauthorized hardware or corrupted loader files. Common Fixes for "Failed 2" Disable Anti-Virus:
Your PC's security software (including Windows Defender) often flags the loader as a "false positive" and deletes critical
files required for it to run. Disable your anti-virus and restore any quarantined files related to VCDS. Check USB Drivers:
Ensure the correct Ross-Tech USB drivers are installed. If the device manager shows an "Unknown Device" or "Ross-Tech HEX-USB" with a warning, manually update the driver from the C:\Ross-Tech\VCDS\ Match Loader and Firmware:
The Kolimer loader must match the specific firmware version on your cable's chip (e.g., ATmega162 or STM32). If you updated the VCDS software without using the loader, it may have "deactivated" or bricked the cable's license. Clean Reinstall:
Uninstall VCDS and delete the installation folder completely. Disable your internet connection.
Reinstall the specific VCDS version provided with your cable. VCDSLoader.exe
(Kolimer) into the installation directory and always use it to launch the program instead of the default shortcut. When to Reflash the Cable
If the hardware is still not recognized after a clean install, the cable's internal EEPROM may need to be reflashed using tools like VAGCOM_EEWriteLang.exe
or a specialized firmware updater found in "Loader 9.2" archives. Are you using a or an older HEX-USB+CAN
The story of the "VCDS Loader Kolimer Failed 2" error is a classic tale of a garage hobbyist's battle with a stubborn piece of diagnostic software. The Saturday Morning Project
Leo had his 2018 GTI up on jack stands. He wasn’t doing anything major—just some basic tweaks to the comfort settings using his VCDS diagnostic system. He plugged in his HEX-V2 interface, fired up his grease-stained laptop, and double-clicked the icon for the "Kolimer Loader."
But instead of the familiar interface, a small, cold window popped up: "Failed 2." The Troubleshooting Rabbit Hole
Panic didn't set in immediately; Leo was a veteran of the "VAG-COM" days. He knew that sometimes these HEX-V2 interfaces—especially clones—could be temperamental if they sensed an internet connection or if the firmware was out of sync. He tried the usual tricks:
The Cable Swap: He moved the USB cable to a different port, hoping a fresh connection would wake it up.
The Driver Refresh: He dove into the Device Manager to uninstall the Ross-Tech device and clear out any conflicting driver stacks.
The Loader Relocation: Remembering a tip from Reddit, he made sure the VCDSloader.exe was in the exact same folder as the main program. The Bricked Reality
As the sun began to set, the "Failed 2" message remained. Leo realized he might have made the ultimate mistake: he’d left the Wi-Fi on. When VCDS checked for updates and saw a newer version available, it may have partially "bricked" his non-genuine cable.
He spent the rest of his Saturday night on forums, reading about "VII Plus Loaders" and "flashing red lights". In the end, Leo learned the hard way that when it comes to loaders and diagnostic clones, one small update can turn a powerful tool into a very expensive paperweight.
