Common Questions
How is my module protected during shipping?
We recommend using tracked, insured shipping. Wrap your ECU in an anti-static bag and place it in a well-padded box. We also recommend taking photos before shipping as documentation.
Can I ship on weekends or holidays?
Contact us first so compatibility and service requirements can be reviewed before shipping. Packages received over weekends or holidays are processed on the next business day.
What if I need faster turnaround?
Turnaround is estimated after inspection and compatibility review. Timing depends on module type, condition, required procedures, parts availability, and current workload.
What's your warranty on repaired modules?
All our work includes quality assurance testing. If an issue appears related to the completed service, contact us promptly so the module, service records, installation conditions, and vehicle-side requirements can be reviewed. Warranty coverage, when applicable, depends on the service performed and the cause of the reported issue.

Do not ship a module until DG Autohaus has reviewed the vehicle information, module identification, service request, and compatibility.
