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.

POST 1 / ORIGINAL POSTEROriginal post

Hi, I'm getting some parts together for a service at home. Looking at pollen filters on ECP there are a few that are all slightly different sizes.... Rather than taking mine out I wondered if someone knew the exact size of the filter? Or perhaps they don't need to be an exact size to fit well? I have most of the workshop manuals and the parts PDF but I can't see any sizes on there. Also - will any magnetic sump plug that's M18 x 1,5 replace my existing sump plug? Cheers!
