MT Internal Quality-Control Standard
Used OEM Parts Supply Verification Process
VIN + Original-Part Photos. Double-Checked Before Order Confirmation.
To reduce fitment errors and improve installation success, MT verifies the vehicle, the original component and the replacement part before confirming a used-parts order. This process also prevents security-encrypted modules from being supplied to workshops without the required programming capability.
Verification reduces avoidable supply errors. It does not make every used electronic module plug-and-play.8 Verification Steps Before Dispatch
Collect Vehicle & Repair Data
Full VIN, model year, sales region, engine/transmission, requested part and current fault codes.
Assess Domestic Supply Feasibility
Check official market availability and stable dismantling channels. A non-official-import vehicle is assessed case by case—not automatically rejected.
Verify Original-Part Photos
Require clear images of the OE label, connector pins, front/rear housing, left/right position, mounting brackets and installed condition.
Cross-Check Hardware & Configuration
Compare VIN, OE number, hardware/software IDs, pin layout, trim configuration and model-year differences. Conflicts must be resolved before sourcing.
Classify Installation Risk Before Quote
Classify the part as security-encrypted, coding/calibration required, or unbound hardware. Required workshop procedures are disclosed before quotation.
Confirm Programming Responsibility
Programming is not included by default and is provided only when stated in a written quotation. The customer’s workshop must provide compatible equipment, a stable power supply and an on-site technician, and programming must be booked in advance. If compatible equipment is not available, we cannot provide programming.
Source, Inspect & Document the Part
Source through established dismantling channels, inspect condition and send actual part/label photos to the customer for approval.
Complete Final Dispatch Re-Check
Reconfirm the agreed model, OE number, label photos, left/right position, hardware shape and programming responsibility before release.
Risk Classification Before Quotation
Security-Encrypted Modules
Immobilizer, ignition, keyless-start and other anti-theft electronics. Programming authorization and specialist capability are mandatory.
Coding / Calibration Required
Modules requiring coding, adaptation, calibration or parameter writing after installation.
Unbound Hardware
Parts primarily verified by OE number, connectors and hardware specification, without vehicle security binding.
Programming: Not Included Unless Stated in a Written Quotation
Coding and programming are not included with the part by default; they are provided only when stated in a written quotation. The customer’s workshop must provide compatible equipment, a stable power supply and an on-site technician, and programming must be booked in advance. If compatible equipment is not available, we cannot provide programming. Where possible, MT may arrange or coordinate programming, but that service remains separate and separately quoted.
Do not order security or configuration-linked modules based only on matching OE numbers or connectors.
Clear Responsibility. No Hidden Assumptions.
MT Auto Parts Is Responsible For
- Vehicle and supplied-document review
- Original/replacement-part photo comparison
- Supply-feasibility confirmation
- Part condition and dispatch inspection
- Programming only when stated in a written quotation
Qualified Customer Workshop Is Responsible For
- Physical installation and on-vehicle diagnostics
- Licensed diagnostic equipment, authorized accounts and security access
- Local programming when remote service is unavailable
- Immobilizer matching, adaptation and calibration
- Final vehicle safety and functional validation
Final Responsibility Boundary
This SOP completes all practical pre-shipment verification available to MT. Physical installation, unsupported offline programming, immobilizer matching, adaptation, calibration and final vehicle safety validation remain the responsibility of the customer’s qualified workshop.
Prepare your full VIN, fault codes and clear original-part photos.

Remote programming is not included with a part unless it is expressly stated in a written quotation; where available we may introduce an independent third-party programming provider, and that service is separate and separately quoted. A programming failure does not by itself prove that the supplied part is defective. Questions? See our Contact page.
