These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

My 98 Boxter check engine light is on. After I took the car to the mechanic he found faults P0410 secondary air system and P1411 manufacturer control emissions. He said he tested secondary air system, found air pump not coming on, he traces wiring and cleaned all connectors, pump ran, then tested air pump control valve, it was not operating. He changed it. He charged me $600. I brought the car back home and check engine light came back on. I am planning to take the car back to him. Any suggestion as what causes this problem. Thanks.
