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.

As I understand it, certain systems - secondary air, O2 sensors, etc - will not recored codes for a certain number of cycles after they've been cleared. So I have several questions
1. Does anyone know which Boxster systems must wait for a certain number of cycles before recording new faults?
2. Are the cycles number of starts, number of miles driven, or a combination of both. If so, what are the relevant numbers
3. Does the ECU store faults before a waring light comes on.
Thanks
1. All the emissions’ systems require "drive cycles" before the DME resets from "not ready" to "ready".
2. Area of debate; some codes take longer than others, and this appears to be on purpose to foil clear codes and then trying to sneak the car through inspection. All require several "cold start, warm up to full temp, drive and highway speeds, and cool down to cold" cycles. So it could be anywhere from 50 miles to over 100, dependant upon the code(s) or combination of codes involved.
3. Yes, they are called "pending codes".
