Read evidence and context

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 performed work without a confirmed outcome: 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.

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.

7 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.

POST 1 / ORIGINAL POSTEROriginal post

Does anyone know if the M96.22 & M96.23 are direct-swappable? If not, what's the difference between the two? I may have a source on a 2003 M96.23 motor that I may want as a backup for my 2002 M96.22, if they're compatible. Thanks in advance!

POST 2Original post

i don't know the codes, but if you want to go from a 5 chain to a 3 chain engine, the engine control is different.

Thanks, Quadcammer. I honestly don't know for sure whether I have a 5-chain or 3-chain. My car is a 2002 base and the donor car is a 2003. All I know from the catalog is that the 2002 has the M96.22 engine and the 2003 has the M96.23. Do you by chance know which year they went from 5 chains to 3?

POST 4Original post

Quotes source post: 623598

The year is 2003. So the engine you want to swap (3 chain) needs the ME 7.8 engine managment system, which is different from yours.

That answers that. Thank you.

Thanks, I realize I wouldn't want to get into all that. I'd rather just do a direct swap.
