An A4 B9 workflow: dated mileage and invoices, Audi digital service records, accident checks, diagnostics and an independent inspection.
An Audi A4 B9 advertised with low mileage may still have gaps in its history. Compare the VIN, dated readings and documents, then inspect the car before paying.

Screenshot source: carVertical ↗ Buying guide Editorial review: 22 October 2026Resolve any difference between vehicle markings, documents and the report before paying a deposit. An empty report does not confirm that the car has never been damaged.
Request a clear photo of the VIN on the car and the relevant documents, then arrange dates and mileage readings in order. Keep a budget for an independent inspection.
There is no magic reading that guarantees 'genuine mileage'. Compare independent documents, available Audi-network records and the physical inspection.

Some models show the VIN through the windscreen. A door-frame label or a stamped marking may be elsewhere; check the manufacturer’s manual for your model.
Compare the marking with the vehicle documents and report. Do not confuse an engine code or a part number with the VIN.
Do not scrape or alter markings. If a number is missing, hard to read or does not match, ask a specialist to verify the vehicle’s identity.
Fictional example: an invoice showing 182,000 km in 2022 and an advertisement showing 139,000 km in 2025 conflict. A recording error or documented instrument replacement needs evidence; this example is not an actual vehicle history.
Audi describes an online service record accessible through its service centres. With the owner's cooperation, request confirmation of available VIN-linked entries and supporting invoices. Confirm local access arrangements for a prospective buyer.
An upcoming-service display is not a complete history. Compare dates, mileage and operations against invoices; work outside the network may need other evidence.

3. Damage: reconcile the report with the actual car| Finding | Next check |
|---|---|
| No damage entries | Arrange a body inspection: missing records do not rule out repairs. |
| Repainted panel | Check joints, adjacent parts and records; repainting alone does not determine severity. |
| Documented damage | Compare earlier photographs, repair invoices, alignment and safety-system checks. |
| Airbag or ADAS faults | Request diagnosis and repair/calibration evidence, not simply cleared codes. |

I have a dated VIN/mileage timeline, not only screenshots. I checked Romanian records and import documents. The owner cooperated with checking available Audi history. Conflicts and any replaced instruments are documented. Bodywork, structure and safety systems were inspected. I have a diagnostic report and quotes for confirmed defects.Not alone. Compare the display and service reminders with documents and independent records.
Does a clean A4 B9 history report mean no accidents?No. Repairs may never reach the consulted databases. Body and structural inspections are still necessary.
Does any difference between module readings prove rollback?No. It depends on what each module records and any documented replacements. Ask a specialist to interpret it.
