Common workshop questions
Does this knowledge center upload or process ECU files?
No. These are public preparation routes. Private upload, credits, messages and delivery remain inside the authenticated portal.
Can a service be confirmed from a vehicle model alone?
No. ECU or TCU identity, software context, read method, file quality and workshop notes can all affect support and review.
Where are status and completed files shown?
Customers track request status, messages and available downloads inside their protected dashboard.
