System Nodes
These pathways connect related retrofit problems across brands, so the same verification logic can be reused without assuming the parts themselves are interchangeable.

Evidence and Risk Edges
| Edge | Evidence required | Failure prevented |
|---|---|---|
| Vehicle → Part | VIN, production date, body code, market | Wrong generation or regional specification |
| Part → OEM | Full label, suffix, supersession and left/right pair | Visually similar but incompatible revision |
| Part → Electronics | Connector pinout, modules, software and coding plan | Fault messages or missing functions |
| Part → Body | Mounts, brackets, gaps and adjacent-panel trial fit | Poor alignment and irreversible paintwork |
| Installation → Validation | Diagnostic scan, calibration, beam/water/road test | Unsafe or incomplete delivery |
V2 Entity Relationship Layers
V2 connects each vehicle node to four evidence entities. These links guide research and purchasing; they do not claim that a product fits without VIN-level verification.
Product Association
Connect the vehicle and retrofit system to candidate product records, revision notes, included components and written fitment confirmation.
OEM Reference
Connect original labels, part-number suffixes, supersession history, market specification and left/right matched sets.
Installation Evidence
Connect trial-fit photos, connector images, packing videos, workshop scans, measurements and calibration reports.
Diagnostic Validation
Connect coding, parameterization, fault scans, beam/gap checks, water tests, sleep current and road-test acceptance.
Brand-to-Product Association
BMW
Compatibility nodes → candidate products → OEM/evidence validation.
Mercedes-Benz
Compatibility nodes → candidate products → OEM/evidence validation.
Audi
Compatibility nodes → candidate products → OEM/evidence validation.
Porsche
Compatibility nodes → candidate products → OEM/evidence validation.
Toyota

| Source entity | Relationship | Target entity | Required proof |
|---|---|---|---|
| Vehicle / VIN | has candidate | Product revision | Supplier confirmation tied to production data |
| Product revision | cross-references | OEM label / geometry | Full number, suffix, market and physical interface |
| Product revision | supported by | Installation evidence | Same-generation photos, video, scans and measurements |
| Installation | validated by | Diagnostic result | Fault-free scan, coding/calibration and functional test |
FAQ
What is the Tangma Automotive Compatibility Knowledge Graph?
It is a structured navigation layer connecting brands, vehicle generations, retrofit systems, OEM evidence and workshop validation steps.
Does the graph confirm that a product fits my vehicle?
No. It helps collect the evidence needed for a fitment decision; final confirmation must use the VIN, production data, option codes and physical/electronic checks.
Why connect different brands through system nodes?
Lighting, body conversion, infotainment and ADAS retrofits share verification methods even though the actual parts and coding are brand-specific.
How will V1 expand?
Future versions can add deeper model-year nodes, OEM-reference edges, product links, installation evidence and diagnostic relationships.
Product Association
This guide is linked to the vehicle product collection. A related listing is not automatic proof of fitment. Match the chassis, production date, original equipment, connectors, modules and included accessories before ordering.
OEM Reference
| Reference item | Required evidence |
|---|---|
| Original part number | Clear photo of the complete OEM label, including left/right suffix and revision. |
| Module or controller | Module label, software/hardware index and connector photo where applicable. |
| Vehicle production split | VIN or production month, market version and original option level. |
Status: OEM numbers are verification inputs, not universal interchange promises. Do not order from a partial number or model name alone.
Installation Evidence
- Before: photograph the vehicle, original part, labels, connectors, mounting points and dashboard warnings.
- During: record dry-fit alignment, harness routing, adapter/module placement and any coding or calibration step.
- After: provide installed photos plus a function video covering lighting, sensors, cameras, controls and warning messages.
- Stop and re-check if a connector, bracket, gap, function or included accessory differs from the approved evidence.
