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.

5 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.

POST 1 / ORIGINAL POSTEROriginal post

Hello - bought a 1999 C2 late last year- the seller gave me a copy of an invoice where Porsche replaced the engine in 2001 due to an internal coolant leak. The invoice shows the replacement engine number as M660166X16044. I thought that all these engine numbers started with M96. Thoughts? The car is stored right now, so I am unable to check the engine number for myself.

POST 2Original post

check this out, it will help you understand. http://www.porscheclubgb.org/clientftp/Register/996/faq_engine_transmission_codes.pdf

POST 3 / ORIGINAL POSTEROriginal post

Thanks Tony- The only intrepretation that I can think of is that the M66 prefix is a typo-should be M96. The other numbers make sense after looking at your reference.

POST 4Original post

I agree. The engine stamping has to be M96 xxx etc.

POST 5Original post

These stampings are pretty damn hard to read. Im also thinking it was misread.

This is a source reference. Confirm exact model applicability in the original material.
