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.

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.
Leading evidence: 'headlights' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'headlights' (1 discussions; 0 report identifying it and 1 suggest it). No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

I was helping my son with his math homework yesterday, when I noticed "911", "991", and "997" in a list of
prime numbers
. 996 was obviously missing. It got me wondering how many Porsche designations are prime. Was this by conscious choice, or by happenstance?
So, for your Friday entertainment, I present the following useless information:
Number of Porsche unique numeric designations (under 3513): 223
Number of prime numbers (under 3513): 490
Number of Porsche Primes (under 3513): 29
Here are the Porsche model designations that are prime:
Type Year/Description

953 1984 4x4 version of 911 Carrera for Paris-Dakar Rally
991 2011 7th generation of the "911" Carrera and Carrera 4
997 2004�2011 6th-generation "911" Carrera and Carrera 4
1997 1973 Urban car studies, two-cylinder air-cooled rear�engined
2539 1975 SAVE mobile medical-assistance project for Technology Ministry (see 2614)
(
Designations per Wikipedia
. Duplicate designations such as 911/01 and non-numeric designations omitted.)
In the list of all numbers between 1 and 3512, the likelyhood of 29 numbers to occur in both the prime number list and the Porsche designation list purely by chance is very high (likelihood ratio p-value = 0.67)
tl;dr
: Looks like it's random. Now you know.
