Professional workflow
The catalog is only the start.
Real request quality comes from the intake flow: vehicle context, original file, service scope, notes, review status and delivery all stay connected to the same customer order.
Step 1
Choose service scope
Select the closest ECU, TCU, diesel, diagnostic or support category before the secure upload flow starts.
Step 2
Prepare technical context
Vehicle, engine, ECU or TCU details, read method, exact fault codes and workshop notes stay attached to the request.
Step 3
Submit securely
Files are submitted only through the authenticated customer portal, with credit and access checks on the server.
Step 4
Track review and delivery
Status, customer-visible messages, delivery and revisions remain in the private dashboard.

FAQ
Service catalog questions
Is every listed option automatically available for every vehicle?
No. Availability depends on the vehicle, controller, read method, file quality, hardware state and submitted notes. Complex or unclear work stays review-first.
Does this public service page upload or modify files?
No. This is a public service catalog. File upload, payment, request status and delivery happen only inside the authenticated customer portal.
Why does MG AutoTech show more services than a basic ECU solutions page?
Workshops often need more than one simple category. MG AutoTech separates performance, aftertreatment, diagnostics, TCU, function requests and support add-ons so the request can be prepared clearly.
What should I prepare before opening a request?
Prepare the original file, vehicle details, engine, ECU or TCU information, read method, exact DTCs if relevant and a short workshop note.
