The Kolimer loader requires certain .dll files (e.g., msvcr100.dll, kernel32.dll calls) or a specific folder structure. If you placed the loader in the wrong directory, step 2 fails.
Before you throw your cable out the window, follow this diagnostic flow. Perform these steps exactly in order.
Let’s be realistic. The "VCDS Kolimer failed 2 new" error appears because Ross-Tech actively fights clones. Every time Kolimer releases a new loader, Ross-Tech updates their software within weeks. The "failed 2 new" error is a cat-and-mouse game.
If you need reliability for professional use: Purchase a genuine Ross-Tech HEX-V2 or HEX-NET cable (starting at $199 for 3 VINs). You will never see this error again, you get live updates, and support.
If you are a hobbyist: Stick to an older, known-stable combination. For example:
Do not update Windows, do not update VCDS, and freeze your system.
| Step | Action | Result |
|------|--------|--------|
| 1 | Reinstall VCDS (19.6.3 – Kolimer recommended version) | No change |
| 2 | Replace loader.exe with alternate version (v1.2, v1.4) | Failed 2 New persists |
| 3 | Test on different vehicle (2010 Golf vs. 2018 Tiguan) | Fails on newer vehicle only |
| 4 | Test with genuine Ross-Tech HEX-V2 | Passes all modules |
| 5 | Inspect interface PCB | Clone board – no security IC |
Corrupted Kolimer file? Try obtaining a fresh copy (different source). Some users report that “Kolimer v3.6” or “Kolimer 2019” resolves “Failed 2 New.”
In the VCDS interface, if the software cannot talk to a specific control module, it often displays a message in German or a translation error.
What this means: Your diagnostic cable is talking to the car's main gateway, but it cannot reach a specific module (like the Engine, ABS, or Transmission).

The error message "vcds kolimer failed 2 new" typically appears when using Kolimer loaders with unofficial or "clone" VCDS (VAG-COM Diagnostic System) interfaces. This failure usually indicates a communication breakdown between the third-party loader software and the interface hardware, often triggered by a mismatch in software versions or anti-virus interference. Understanding the "Failed 2 New" Error
This specific error is associated with the Kolimer loader, a tool used to bypass official Ross-Tech licensing on clone cables. The "Failed 2 New" status often means the loader cannot properly initialize the interface because:
Software Version Mismatch: The loader version you are using does not support the specific VCDS software version installed on your PC.
Firmware Mismatch: The cable's firmware has been updated (or attempted to update) by the official Ross-Tech software, causing the third-party loader to lose control.
Security Conflicts: Windows Defender or other anti-virus software has flagged and quarantined essential loader files, preventing them from "patching" the VCDS executable. Step-by-Step Troubleshooting Guide
If you encounter this error, follow these steps to restore functionality: 1. Disable Anti-Virus and Windows Defender
Third-party loaders like Kolimer are frequently flagged as "False Positives" because of how they modify software behavior.
Disable Real-time Protection: Temporarily turn off your anti-virus before launching the loader.
Add Exclusions: Add the entire VCDS installation folder to your anti-virus exclusion list to prevent it from deleting the loader in the future. 2. Perform a Clean Reinstall
Conflicting drivers or corrupt installation files are common culprits.
Uninstall VCDS: Remove the software via "Apps & Features" in Windows.
Remove Drivers: In Device Manager, find the Ross-Tech interface, right-click it, and select "Uninstall device," ensuring you check the box for "Delete the driver software for this device".
Reinstall: Install the specific version of VCDS that was originally bundled with your Kolimer loader. Do not use the latest version from the official Ross-Tech Download Page unless your loader explicitly supports it. 3. Update the Loader Version
If you have updated your VCDS software to a newer version (e.g., from v20 to v23 or v24), your old Kolimer loader may no longer work.
Search for the latest Kolimer Loader compatible with your VCDS version.
Ensure the VCDSLoader.exe is placed directly in the main VCDS installation directory before running it. 4. Fix a "Bricked" or Stuck Interface
If your interface shows flashing red lights, it may be stuck in an "update mode" or have corrupted firmware. vcds kolimer failed 2 new
Force Update: If you are using a HEX-V2 or HEX-NET style clone, try using the VCI Config utility to force a firmware update, though this carries a risk of permanently "bricking" some clone cables.
Check Connection: Ensure you are using a high-quality USB cable. Sometimes a simple cable swap can resolve "enumeration" errors that the loader misinterprets. Summary of Best Practices To avoid the "Failed 2 New" error in the future:
Stay Offline: Always disconnect your PC from the internet when using clone cables to prevent the software from checking for official updates.
Use the Loader Only: Never launch VCDS using the original vcds.exe shortcut; always use the VCDSLoader.exe provided with your interface.
The VCDS Kolimer software is a specialized loader designed to bypass licensing restrictions on third-party (clone) VCDS diagnostic interfaces. When a "Failed to New" error occurs, it generally indicates that the loader cannot properly initialize the communication bridge between the modified software and the cable firmware. Core Troubleshooting Steps
If your VCDS Kolimer loader is failing to initialize, follow this sequence to restore functionality: Clean Reinstall (Driver & Software)
Open Device Manager, find the Ross-Tech device under "Universal Serial Bus controllers," right-click it, and select Uninstall device. Ensure you check the box for "Delete the driver software for this device". Uninstall the VCDS software entirely from your system.
Reinstall the specific VCDS version provided with your cable, then reconnect the interface to refresh the driver stack. Antivirus & Permissions
Disable Real-time Protection: Modern antivirus software often flags Kolimer loaders as malicious because they modify program execution. Temporarily disable your antivirus or add the VCDS installation folder to your Exclusions list.
Run as Administrator: Ensure you are launching the VCDSLoader.exe (Kolimer) with administrative privileges to allow it to hook into the system processes. Interface Configuration
Connect your cable to the PC (vehicle connection is not always required for initial config).
Launch the loader, navigate to Options, and select the USB port.
Click Test. If the interface is found but says "Questionable" or "Unregistered," the Kolimer loader is usually failing to patch the license in real-time. Hardware Verification
Check for a "License Revoked" message. If the cable was connected to the internet while an official Ross-Tech update was running, the firmware may have been blacklisted.
If the cable fails to respond entirely, you may need to use a firmware flashing tool (like MPROG) to restore the original clone firmware. Key Terms for Diagnostics
SRI Reset: Used to clear service reminders once the interface is communicating correctly.
Reset Counter: A value within fault codes that indicates how many "clean" driving cycles are needed before a fault clears itself from memory. Follow-up Questions:
Are you seeing a "License Revoked" message in the VCDS status window? The Kolimer loader requires certain
What version of VCDS (e.g., 23.3, 24.1) are you attempting to use with the loader? HEX-V2 updates
When a VCDS Kolimer (a common clone interface) fails or is "blocked," it's usually because the Ross-Tech software detected it as non-genuine or a firmware update corrupted the internal ATMega chip. Troubleshooting: VCDS Kolimer Failed / No Interface Found
If your interface has stopped working after a software update or a "forced" firmware refresh, follow these steps to recover functionality. 1. Clean Software Environment
Uninstall and Purge: Completely uninstall VCDS and the Kolimer Loader.
Clean Registry: Use a tool like CCleaner to remove leftover Ross-Tech registry keys that may be flagging the hardware.
Disable Security: On Windows 11, you may need to disable Memory Integrity (under Core Isolation) to allow the drivers to initialize properly. 2. Hardware Recovery (The "Flash" Method)
If the cable is not recognized at all, the firmware on the internal ATMega chip likely needs a manual reset:
Use the Loader: Never open VCDS from the original desktop icon; always use the specific Loader app provided with your kit.
Hardware Reflash: If the device is "flagged," you may need to use a separate programmer (like a USBasp) to re-flash the EEPROM/Flash memory of the ATMega chip with a clean firmware version (e.g., v1.96). 3. Proper Connection Sequence To avoid "Interface Not Found" errors during a lead test:
Power First: Plug the interface into the car's OBD-II port first to power the device.
USB Second: Once the interface has power, connect the USB cable to your laptop.
VCI Config: If the lights are flashing red, open the VCI Config utility within the VCDS directory and try to "Check for Updates" while the laptop is offline to force a local reset. 4. Common Error Fixes
Unsupported Identifier: If Device Manager shows "Ross-Tech Direct Interface" (PID_FA30), the newer Ross-Tech drivers will not support it. You must manually roll back to the drivers provided by the clone manufacturer.
Windows S Mode: Ensure your laptop is not in S Mode, which prevents the installation of non-Microsoft Store diagnostic software.
Heads-up: VCDS Kolimer “Failed 2 – New” Error
If you’re using the Kolimer cracked VCDS loader, you might have started seeing:
Failed 2 – New
This seems to be happening more often now. It likely means:
🔹 The loader is detecting an updated check from genuine VCDS software
🔹 The crack is no longer bypassing the protection
🔹 Time to either find a newer loader version (if any exists) or go legit Do not update Windows, do not update VCDS,
Just a reminder – unofficial loaders can also brick your interface or give incorrect diagnostics. Proceed with caution.
