At ECU Fix, we specialise in fast, reliable, and cost-effective Audi ECU repair services. Whether you’re dealing with a faulty engine ECU, ABS pump, gearbox module, or power steering unit, we’re here to help. Instead of replacing the unit, we repair it—saving you both time and money.

If your ECU is listed in our online repair catalogue, we will test it within 24 hours—or the repair is completely free. However, if your unit isn’t listed, don’t worry. In most cases, we can still test and repair it. Just send us your part number or vehicle information and we’ll confirm compatibility.

In addition, all of our repairs come with a lifetime warranty, so you can drive away with confidence.

Audi ECU Repair Services

We cover all major Audi electronic systems. Therefore, no matter where the fault lies, ECU Fix has a solution.

Audi Engine ECU Repair

Your engine ECU plays a vital role in starting and running your Audi. If it begins to fail, you may notice:

  • No-start or hard start conditions
  • Misfires or rough running
  • Diagnostic tool communication issues
  • Internal data corruption or electrical failure

Fortunately, our team can repair most of these faults quickly and affordably.

Audi ABS Pump Repair

A faulty ABS pump can compromise braking safety. That’s why it’s important to act fast when you notice:

  • ABS or ESP warning light on
  • Brake pressure sensor faults
  • Pump motor not engaging
  • Loss of communication with diagnostics

We support Bosch, TRW, and ATE units commonly fitted in Audi vehicles.

Audi Body Control Module Repair

The body control module (BCM) manages key features like lights, windows, and locks. When it fails, multiple systems may stop working. We repair issues such as:

  • Central locking or electric windows failing
  • Constant battery drain
  • Immobiliser-related no-start issues
  • Internal water damage or circuit faults

As a result, repairing your BCM can resolve several electrical issues at once.

Audi Instrument Cluster Repair

When your instrument cluster fails, it affects both functionality and safety. We can help with:

  • Flickering or blank displays
  • Dead pixels or dim lighting
  • Faulty gauge readings
  • Warning lights that fail to illuminate

By repairing rather than replacing, you avoid reprogramming and reduce costs.

Audi Gearbox ECU & Mechatronics Repair

If your Audi struggles to shift smoothly or is stuck in gear, the gearbox ECU or mechatronic unit may be at fault. Common issues include:

  • Gearbox stuck in limp mode
  • Harsh or delayed gear changes
  • No drive or reverse
  • Communication faults with the TCU

Audi Airbag Module Repair

A lit airbag or SRS warning light can be a sign of crash data or internal faults. We fix:

  • Crash data that needs clearing
  • SRS communication problems
  • Water-damaged modules
  • Internal circuit errors

In most cases, you can simply refit the repaired unit—no coding required.

Audi Electric Power Steering Repair

Power steering faults affect driveability and safety. Therefore, it’s important to repair issues like:

  • Heavy or inconsistent steering
  • EPS warning lights
  • Loss of power steering assist
  • Torque sensor or motor failure

Each unit is thoroughly tested before we return it to you.
