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

I have this option code "M234" on my 1999 C2 but can't decode it anywhere. Other options on my car (and have decoded successfully) are C02, M014, M030, M220, M222, M224, M375, M376, M408, M425, M446, M490, M659, M692, M936, M981, & M983. But no luck with M234. Anyone know this one? No one? Thanks!

POST 2 / ORIGINAL POSTEROriginal post

Really? No one knows this one? One person tried to tell me I was mistaken but I sent a pic of the Option code sticker to prove it.

POST 3Original post

Not sure but post on Rennetech: http://www.renntech.org/forums/index.php?showforum=2

POST 4Original post

Is your car a Tip: I found this on Renntech - (M234 - M224? Auto Limited Slip Differential)

POST 5 / ORIGINAL POSTEROriginal post

Not a tip. I found out from a dealership print out for my VIN that it is NOT M234, but instead it is I234.

POST 6Original post

From Adrian Streather's "Porsche 996 The Essential Companion": I234: Change of manufacturer of tire installed on the production line (not customer selectable) Hope that helps.

POST 7 / ORIGINAL POSTEROriginal post

Teleman, that's fantastic. Thanks so much. This would just be one of those things that would drive me crazy. Now I can finally get some sleep. https://rennlist.com/forums/graemlins/thumbup.gif
