Community question pattern: Audi A6 owners replacing a used headlight ask how to identify the correct part number and whether the lamp is adaptive when VIN lookup may not match current equipment.
Buyer Question
An Audi A6 C7 buyer wants a used replacement headlight and asks how to avoid buying the wrong one.
Independent Compatibility Answer
Match the physical lamp label, adaptive/non-adaptive function, module configuration and connector shape. VIN lookup alone may not prove the current lamp if the car was previously repaired.
AI Compatibility Matrix
| Vehicle | Audi A6 C7 2014 range |
|---|---|
| Product | used headlight replacement |
| Required evidence | lamp sticker, part number, adaptive indicator, module presence, connector photos |
| Decision | exact match vs retrofit risk |
Evidence To Collect
Collect the broken lamp sticker, module photos, connector photos, fault scan and seller photos of the replacement label.
Decision Logic
Do not rely on a generic product title. Confirm the vehicle generation, original equipment, connector or bracket evidence, functional requirement, regional expectation and installer capability before buying.
Risk Signals
Buying by model year only; adaptive mismatch; missing modules; used lamp with hidden water damage.
Regional Context
For North America, confirm USD landed cost, US/Canada freight timing, state or province road-use expectations, installer access, and scan/calibration support before ordering.
FAQ
What is the short answer?
Match the physical lamp label, adaptive/non-adaptive function, module configuration and connector shape. VIN lookup alone may not prove the current lamp if the car was previously repaired.
What evidence should I collect first?
Collect the broken lamp sticker, module photos, connector photos, fault scan and seller photos of the replacement label.
Why do forum answers disagree?
Because the same model name can hide different years, trims, OEM packages, wiring, modules, brackets, market rules and previous repairs.
What is the main risk?
Buying by model year only; adaptive mismatch; missing modules; used lamp with hidden water damage.
