Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi all, Has anyone ever changed their o2 sensor? I just got my car (997.1 Carrera S) and I understand it isn't too hard from reading online although would be good to get some local thoughts? Also where is best to buy from also? Cheers, Mitch
