The advent of sophisticated onboard diagnostic systems in vehicles has been a game-changer for mechanics and car enthusiasts alike. These systems, often accessed with tools like VCDS (Vag-Com Diagnostic System), provide invaluable insights into the health of your vehicle. However, deciphering the codes these systems throw up can be daunting. One such code that often raises concerns is “000135.” This article aims to demystify VCDS error code 000135, providing a comprehensive understanding of its meaning, causes, symptoms, and solutions.
What Does VCDS Error Code 000135 Mean?
In simple terms, error code 000135 in VCDS specifically points to a problem with the power supply to the anti-lock braking system (ABS) control module. This fault code is often logged as “000135 – Power Supply Terminal 30: Voltage too Low.”
Essentially, the code indicates that the ABS module is not receiving the correct voltage it needs to function properly.

Causes of VCDS Error Code 000135
Several issues can lead to the 000135 error code. Some common culprits include:
- Weak or Failing Battery: A low battery voltage is one of the most frequent reasons for this error.
- Faulty Alternator: The alternator is responsible for charging the battery and powering electrical components while the engine is running. A malfunctioning alternator can lead to insufficient voltage supply.
- Wiring Issues: Damaged, corroded, or loose wiring connections between the battery, alternator, and ABS control module can disrupt the power supply.
- Damaged ABS Control Module: While less common, a faulty ABS control module itself can also trigger this error code.

Symptoms Associated with Error Code 000135
The appearance of the 000135 error code is often accompanied by noticeable symptoms, such as:
- Illuminated ABS Warning Light: The most apparent indicator is the illumination of the ABS warning light on your dashboard.
- Malfunctioning ABS System: You might experience issues with the anti-lock braking system, like wheel locking up during braking.
- Other Electrical Problems: Due to the potential voltage issues, you may encounter problems with other electrical components in your vehicle.

Diagnosing and Fixing Error Code 000135
If you encounter the 000135 error code, it’s crucial to diagnose the root cause before attempting any fixes. Here’s a step-by-step approach:
-
Check the Battery: Begin by inspecting the battery terminals for corrosion and ensuring a secure connection. Test the battery voltage – a reading below 12 volts with the engine off suggests a weak battery.
-
Inspect the Alternator: With the engine running, the alternator should provide a voltage reading between 13.5 and 14.5 volts. If the voltage remains low, it indicates a potential alternator problem.
-
Examine Wiring and Connections: Carefully inspect the wiring harness between the battery, alternator, and ABS control module for any signs of damage, looseness, or corrosion.
-
Consult a Professional: If the above steps don’t reveal the cause or you’re not comfortable working with electrical components, it’s best to seek assistance from a qualified automotive electrician or mechanic.
“Always remember that accurately diagnosing the root cause is paramount when dealing with any fault code,” advises John Miller, a seasoned automotive engineer specializing in vehicle electronics. “Jumping to conclusions without proper diagnosis can lead to unnecessary component replacements and expenses.”
Frequently Asked Questions about VCDS Error Code 000135
Q: Can I still drive my car with error code 000135?
A: While you might still be able to drive, it’s not recommended. Driving with a compromised ABS system can be dangerous, especially in emergency braking situations.
Q: Is it expensive to fix error code 000135?
A: The cost of repair varies depending on the underlying cause. A simple battery replacement is relatively inexpensive, while a faulty alternator or ABS module can be more costly.
Q: Can I prevent error code 000135?
A: Regular vehicle maintenance, including battery and alternator checks, can help prevent this error code. Additionally, addressing any electrical issues promptly can mitigate the risk of more significant problems.
