How we test & write

Our articles are written and edited by the onderdelen.autos editorial team — a team, not an anonymous source. We publish under a team name because the content is a collective editorial product.

We do not invent an individual "expert" to claim authority. If we add a subject-matter reviewer (e.g. a mechanic or MOT inspector) in future, we will name them with their role.

Articles draw on the parts taxonomy and vehicle data the platform maintains, on RDW licence-plate data, and on connected sellers’ inventory. We check factual claims (functions, symptoms, fitment) against multiple sources.

Spotted an error? Tell us via the contact page; we correct it and bump the revision date.

Prices and replacement intervals are indications and ranges, not fixed figures. They vary by make, model, year, and trim. Use them as guidance, not a quote — the live price is always on the seller’s page.

The editorial team drafts articles with AI assistance and editorially reviews them before publication. English, French and German translations are also AI-assisted and editorially reviewed. AI does not replace editorial judgement — it accelerates drafting.

We periodically review articles and update the revision date when content changes. The date under each article shows when it was last reviewed.
