For the 2006 model year (and possibly late 2005 model year), Porsche began using the M97, which is very similar to the last version of the M96.

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.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Today I added a FVD deep sump to my 996 and while doing so I tried to read my engine ID. Looks like my engine number is M96/04AT66Y65978 which I believe to be a model year 2000 motor. My chassis build date is 11/98. So, do I have a factory replacement engine?

POST 2Original post

AT is short for AusTauschmotor or "replacement engine". Therefore, Porsche replaced the motor in your car.

POST 3 / ORIGINAL POSTEROriginal post

Ok. Thanks. Any idea on the year this engine was replaced based on the ID? I think it is a 2000 but I'm not sure.

POST 4Original post

Check with the dealer, it might be in the computer when it was replaced.

POST 5Original post

Good info here... https://www.renntech.org/forums/topi...number-decode/

POST 6Original post

Based on a small sample of one, the year/type of the motor, the date code on the motor and the year of the motor install do not need to be the same with these AT replacement engines. Off the top of my head, for example, my 2002 Carerra has a m96/03 serial number engine with a 2005 date code and a record (dealer invoice) of installation in 2007.

POST 7 / ORIGINAL POSTEROriginal post

Thanks for the info . Looks like the engine would be a 2000 replacement.

POST 8Original post

It's an M96.04, so it is likely newer than 2000. It may have the later larger single row bearing, but you won't know for sure until you pull the trans and look at the IMSB flange. There is no date code in the engine serial number. My 3/98 build has a M96.01. later varieties include the M96.02, M96.03, and M96.04, as I recall. For the 2006 model year (and possibly late 2005 model year), Porsche began using the M97, which is very similar to the last version of the M96.

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