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.
1 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.

2006 C2S with 150,000 miles. these codes come up all at once on my Duromatic and when I clear them they will reappear a week or two later. Car runs fine all the time. With so many codes lighting up all at once, what is the process of elimination to identify the real issue? Any thoughts would be helpful. TIA Johan
