Suggestion · Original poster

If I have a vacuum leak somewhere (for instance, a cracked oil filler pipe), the SAI's check valve won't open at all as it's run on vacuum, causing the SAI pump to be blocked.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

If I have a vacuum leak somewhere (for instance, a cracked oil filler pipe), the SAI's check valve won't open at all as it's run on vacuum, causing the SAI pump to be blocked. Correct?

POST 2Original post

Depends on the severity of the leak, but the short answer is yes, it will keep it from opening.

POST 3 / ORIGINAL POSTEROriginal post

Severe enough to have a substantial performance impact on the car, and to throw lean EML's? I thought I had two issues, a vacuum leak and the SAI issue, but I think it's just one big vacuum leak.

POST 5Original post

Ummm. Sorry to be a pain, but what does SAI stand for?

POST 6 / ORIGINAL POSTEROriginal post

Secondary Air Injection (pump)

POST 7Original post

Vacuum leak is on the check list for SAI codes.
