If you buy and sell vehicles
The pre-purchase report: what it contains, who issues it and how to check it.
Reviewed by Daniel Morales, founder of Reprorace SL, on
The pre-purchase report collects what the vehicle's control units answered to the unit: identification, mileage of each control unit, faults, recent clears, real consumption and battery, with a four-level verdict and any inconsistencies found (for example, a different VIN or an odometer that does not add up).
- Take the vehicle to a workshop that uses Diaglana or ask your usual workshop: today reports are issued by workshops.
- The workshop does a full read and presses “Issue the report” on that read. If the report has a price, it sees it before issuing.
- You receive the signed report with its QR code. Anyone can check that it is genuine on the verification page.
- For electric and hybrid cars, if the same unit reads the high-voltage battery within 24 hours before or after, the battery goes signed into the report.
- If you are a dealer with your own workshop, you issue the reports yourself from Remote sessions › Diagnostics.
Important: It is not a mechanical inspection and does not replace the roadworthiness test. It does not check the vehicle's history or stolen-vehicle databases and does not read airbag data.
