Share what helps. Respect the trade.

Show the diagnostic process

Include vehicle details, codes, symptoms, tests already completed and the evidence behind your conclusions.

Protect customer information

Remove registrations, VINs, names, addresses and other identifying information from screenshots and attachments.

Be constructive

Challenge the diagnosis, not the person. Explain alternatives clearly and avoid dismissive or abusive replies.

Close the loop

When a fault is fixed, update the case with the confirmed cause and repair so future readers benefit.

Declare commercial interests

Sponsors and users connected to a product or service must disclose that relationship when discussing it.
