Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
If a PO ran an Aftermarket Filter for most of the Car's life, then removed it when selling the Car, a MAF failure could occur with the New Owner who was unaware that the Car hadn't run an OEM filter for it's total lifespan.

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.

POST 1 / ORIGINAL POSTEROriginal post

If you had a Mass Air Flow Sensor (MAF) failure at under 100K miles on your Boxster, what type of air filter were you using?

POST 2Original post

Stock filter. 52K miles at time of failure 2000S

POST 3Original post

Hi, You might want to distinguish between One-Owner and Previously Owned vehicles. If a PO ran an Aftermarket Filter for most of the Car's life, then removed it when selling the Car, a MAF failure could occur with the New Owner who was unaware that the Car hadn't run an OEM filter for it's total lifespan. While it's true there would be no way of actually knowing what the PO ran for a Filter, the data, once compiled, could show a statistical significance on Previously Owned Cars which would be suspicious to say the least...
