How to Deactivate ASR and ESP Functions Using an OBD Scanner for Volkswagen

Volkswagen vehicles are known for their advanced safety features, including Anti-Slip Regulation (ASR) and Electronic Stability Program (ESP). While these systems are designed to enhance driving safety, there may be situations where you need to temporarily disable them. This guide will walk you through the process of deactivating ASR and ESP functions using an OBD scanner, specifically for Volkswagen vehicles.

Understanding ASR and ESP

Before we dive into the deactivation process, it's essential to understand what ASR and ESP are and why they're important.

Anti-Slip Regulation (ASR)

ASR, also known as Traction Control System (TCS), is designed to prevent wheel spin during acceleration. It works by reducing engine power or applying brake force to individual wheels when it detects loss of traction.

Electronic Stability Program (ESP)

ESP, sometimes referred to as Electronic Stability Control (ESC), helps maintain directional control of the vehicle during challenging driving conditions. It uses various sensors to detect and correct oversteer or understeer situations.

Why Deactivate ASR and ESP?

While these systems are crucial for everyday driving safety, there are specific scenarios where deactivating them might be necessary:
  • Performance testing on a dynamometer
  • Driving in deep snow or sand where wheel spin is needed
  • Track days or performance driving events
  • Diagnostic purposes

Tools Required

To deactivate ASR and ESP functions in your Volkswagen, you'll need:
  • An OBD-II scanner compatible with Volkswagen vehicles
  • A laptop or smartphone (depending on your OBD scanner type)
  • Appropriate software or app for your OBD scanner

Step-by-Step Guide to Deactivating ASR and ESP

Follow these steps carefully to deactivate ASR and ESP functions using your OBD scanner:

1. Connect the OBD Scanner

  1. Locate the OBD-II port in your Volkswagen. It's usually found under the dashboard on the driver's side.
  2. Plug in your OBD scanner to the port.
  3. Turn on the ignition without starting the engine.

2. Access the Brake Electronics Module

  1. Using your OBD scanner's interface, navigate to the "Control Modules" or "Select Control Module" option.
  2. Look for the "03 - ABS Brakes" or "Brake Electronics" module and select it.

3. Enter the Coding Function

  1. Within the Brake Electronics module, find the "Coding" or "Recode" option.
  2. Select "Software Coding" or a similar option that allows you to modify the module's coding.

4. Modify the Coding

  1. You'll see a multi-digit code. This is the current coding for your ASR and ESP functions.
  2. To disable ESP while keeping Electronic Differential Lock (EDL) active, enter the code "16398".
  3. To disable both ESP and EDL, enter the code "00014".

5. Save and Exit

  1. After entering the new code, save the changes.
  2. Exit the coding function and return to the main menu.

6. Clear Fault Codes

  1. Navigate to the "Clear Fault Codes" or "Clear DTCs" option.
  2. Run this function to clear any error codes that may have been generated during the process.

7. Verify Deactivation

  1. Start the engine and check the instrument cluster.
  2. The ESP light should remain illuminated, indicating that the system is deactivated.
  3. If your vehicle has an ESP button, it should no longer function.

Alternative Method: Manual Deactivation

For some Volkswagen models, there's a manual method to temporarily disable ESP without an OBD scanner:
  1. Turn the ignition on (don't start the engine).
  2. Activate the hazard lights.
  3. Press the accelerator pedal five times in quick succession.
  4. Start the engine.
This method may not work on all models and typically resets when the ignition is cycled.

Accessing ESP Deactivation Function in Popular OBD Scanners

Different OBD scanners may have slightly different interfaces. Here's how to access the ESP deactivation function in some popular scanners:

VCDS (VAG-COM Diagnostic System)

  1. Connect the VCDS interface to your vehicle and computer.
  2. Open the VCDS software and select "Select Control Module."
  3. Choose "03 - ABS Brakes."
  4. Click on "Coding - 07."
  5. In the "Software Coding" box, enter the appropriate code (16398 or 00014).
  6. Click "Do It!" to save the changes.

OBDeleven

  1. Connect the OBDeleven device to your vehicle and open the app on your smartphone.
  2. Go to "Control units" and select "ABS."
  3. Tap on "Adaptations."
  4. Look for "ESP_Funktion" or similar and change the value to "Deactivated."
  5. Save the changes and exit.

Ross-Tech VCDS

  1. Connect the VCDS scanner and open the software.
  2. Select "03 - ABS Brakes" from the control module list.
  3. Click on "Recode - 07" in the advanced functions.
  4. Enter the new coding (16398 or 00014) in the "Software Coding" box.
  5. Click "Do It!" to apply the changes.

Important Considerations

Before deactivating ASR and ESP functions, keep these points in mind:
  • Disabling these safety systems increases the risk of loss of vehicle control.
  • It's recommended to only deactivate these systems in controlled environments or for specific purposes.
  • Always re-enable ASR and ESP for normal road use.
  • Some vehicle functions or warning lights may be affected when these systems are deactivated.
  • Deactivation methods may vary slightly between different Volkswagen models and years.

Reactivating ASR and ESP

To reactivate ASR and ESP:
  1. Follow the same steps as deactivation.
  2. Instead of entering the deactivation code, enter your vehicle's original coding.
  3. If you don't know the original code, consult your vehicle's documentation or a Volkswagen specialist.

Troubleshooting

If you encounter issues during the deactivation process:
  • Ensure your OBD scanner is compatible with your specific Volkswagen model.
  • Check that you're using the latest software version for your OBD scanner.
  • If error codes persist after deactivation, clear them again and recheck.
  • For persistent issues, consult a professional Volkswagen technician.

Legal and Safety Considerations

  • Deactivating ASR and ESP may affect your vehicle's compliance with local road regulations.
  • It may also impact your insurance coverage in the event of an accident.
  • Always prioritize safety and use these instructions responsibly.

Conclusion

Deactivating ASR and ESP functions in your Volkswagen using an OBD scanner can be a useful skill for specific situations. However, it's crucial to understand the implications and use this ability responsibly. Always prioritize safety and comply with local regulations. If you're unsure about any aspect of this process, consult a professional Volkswagen technician.
