Get your ABS pump repaired
If you’re working on a VAG vehicle showing the 01130 fault code—“ABS Operation Signal Implausible”—this guide will walk you through the cause, the symptoms, and the right way to fix it. Whether you’re an independent tech or workshop owner, here’s what you need to know before replacing parts.
🔍 What Does the 01130 Fault Code Mean?
The 01130 fault is logged when the ABS control module receives an inconsistent or implausible operation signal. In simple terms, the module knows something is wrong with how the ABS system is being activated or read—but it can’t trust the data it’s receiving.
This often occurs due to:
- Corrupted signal paths within the ABS module
- Voltage irregularities caused by internal damage
- Intermittent or failing driver circuits in the pump’s electronics
Although the fault can sometimes be caused by external wiring or sensor issues, in many cases, the ABS control module itself is to blame—and that’s where we come in.
⚠️ Common Symptoms of the 01130 ABS Fault
Vehicles affected by this issue may show:
- ABS and/or ESP warning lights on the dashboard
- Brake system warning messages
- Failure during an MOT brake performance test
- Stored or recurring 01130 fault code
- No visible issue with sensors or wheel speed data, making diagnosis harder
If left unresolved, braking safety features like ABS or traction control may become disabled.
🧰 Why the ABS Pump Fails
On many VAG models, the ABS module is integrated with the hydraulic unit. Over time, thermal stress, water ingress, or internal voltage spikes can damage the circuit board or communication drivers. When that happens, signals become corrupted or completely unreadable—triggering fault codes like 01130.
We regularly repair these modules where the fault lies internally, and not with the sensors, relays, or wiring.

FAQs
What is error code 01130 on VW?
Error code 01130 on a Volkswagen refers to “ABS Operation Signal Implausible.” In most cases, this means the ABS control module is receiving an inconsistent or invalid signal. Often, this happens due to internal failure within the ATE MK60 or MK60EC1 ABS pump. Therefore, the fault isn’t typically caused by sensors or wiring—but by the module itself.
What is the code 01130 on Audi A4?
On an Audi A4, fault code 01130 indicates a problem where the ABS system is unable to validate the operation signal. While this can occasionally point to external wiring, it is most often caused by a fault inside the ABS pump module—especially on vehicles using ATE MK60EC1 units. As a result, full module replacement is not always necessary; professional repair is possible.
What does the ABS implausible signal mean?
An implausible ABS signal means the system is receiving data that doesn’t fall within acceptable parameters. Typically, this occurs because of corrupted communication or a damaged circuit inside the ABS unit. Although sensors may appear to work, the internal control board may not be interpreting signals correctly—leading to this fault.
What is the code for the ABS pump fault on a VW?
One of the most common ABS pump fault codes on VW models is 01130 – ABS Operation Signal Implausible. This code frequently shows up when the ABS control module can no longer process signals reliably, usually due to circuit damage or board failure inside the ABS unit. Therefore, targeted repair of the control module is often the best solution.
