General FAQ
See All
What is immo off or immobilizer delete, and will it work for my VW or Audi?
Immobilizer delete (immo off) bypasses the immobilizer in the engine control unit (ECU) of VW and Audi vehicles. It’s used when the vehicle starts but immediately shuts down due to a fault in the immobilizer system, often with fault codes P1570 or P0513. Immo off services will not work if the vehicle does not start at all; it must start and then be shut down due to the immobilizer.
What is module cloning, and do part numbers need to match?
Module cloning involves copying all the data from one module to another, allowing the replacement to function just like the original. While it's generally recommended to match part numbers for compatibility, the necessity can vary by module. Some require exact matches, while others are more flexible and allow cloning between different part numbers. Each product listing on our website specifies the part number requirements. If you're unsure, feel free to reach out for guidance.
Do you have to open the module cases?
We only open module cases when absolutely necessary. For services that don’t require opening, we won’t open the module. However, depending on how badly damaged your original ECU is, sometimes opening the module is the only way to retrieve data. Additionally, some services don’t have a plug-in method at all and require direct access to the board, including soldering or chip replacement. The need to open modules is not specific to us but is sometimes essential depending on the condition of the ECU.
What are the shipping procedures and turn around times?
After purchasing, you will receive an email with shipping instructions. You are responsible for shipping your modules to us, and we will cover the return shipping. You can use any shipping service that is convenient for you. We typically use UPS Ground (3-5 days) for return shipping, but in some cases, we may use USPS or FedEx. Once we receive your package (shipping times depend on how quickly you ship it and the service used), we typically ship it back the next business day. Some services may require a 2-day handling time, depending on the complexity.
For detailed shipping times to and from your location, check out our shipping speed map.
What is the warranty?
We offer a 90-day warranty on programming only. This covers the accuracy of the programming performed, but does not extend to the module hardware itself.
