How Does The ECU Pro's Audi ECU / PCM Mail-In Repair Service Work?

The ECU Pro provides a reliable and affordable Audi ECU / PCM (also known as engine computer) mail-in repair service. If your Audi ECU is malfunctioning, you can send it to us for professional diagnostic testing, repair, or cloning by our experienced technicians.

To begin the ECU repair process for your Audi, follow these simple steps:

  1. Mail Your Audi ECU / PCM
    Remove your Audi ECU and send it to our service center.

  2. Diagnostic Testing and Evaluation
    We perform a comprehensive diagnostic test on your ECU. If we are unable to replicate the issue, we offer you a test ECU to use for up to 14 days. Return it within this period, and the total service fee will be $249.

  3. Repairs or Replacement Based on Diagnosis
    If we can replicate the problem, our technicians will either repair or replace your ECU, depending on the extent of the damage.

Our Audi ECU repair service is fully plug-and-play, meaning no additional coding is needed. This makes the process convenient and efficient, allowing you to get back on the road with confidence.

    Everything you need to know about Audi ECU repairs

    Driving with a faulty ECU can risk further engine damage and decreased performance. It’s recommended to address ECU issues promptly to avoid worsening problems.

    A repaired ECU can restore normal engine operation and prevent issues caused by faulty ECU signals, but regular maintenance is still important for ongoing reliability.

    Yes, you can send related units, such as the BCM or TCM, if you believe they are part of the issue. Please include details for each unit to ensure accurate diagnostics.

    If our technicians determine the ECU cannot be repaired, we will notify you and discuss replacement options, or we can return the ECU to you if preferred.

    Repair costs vary based on the ECU model and repair complexity. To view the exact cost, select your vehicle and service on our website. Starting with a diagnostic test is often best, as testing fees can be applied toward the repair cost.

    Our testing service will identify if we can repair your ECU or if it needs to be replaced. Typically only water damaged ECU or ECU with extensive physical damage require replacements.

    In most cases, our repairs return the ECU to plug-and-play status. However, some Audi models may require additional programming or adaptation after installation, which we will inform you about if necessary.

    Before removing the ECU, use an OBD2 scanner to record any fault codes. Then, package the unit securely and include your contact information and a description of the issue for our technicians.

    In many cases, an Audi ECU can be repaired rather than replaced. Our technicians can often fix communication errors, electrical faults, and software issues, saving you the cost of a new unit.

    Typically, Audi ECU repairs take 3-7 business days, depending on the issue’s complexity. Once repaired, the ECU will be promptly returned to minimize your vehicle’s downtime.
