996 Engine Serial Number Code Help

Recommended Posts

New P-Car owner and new to the forum, sorry if I'm breaking any protocol but it looks like this type of thread is common.


99 c2 cab tip LHD US


Engine reportedly replaced a few years ago. Maybe around 2011- 2012. Stamp is very faint but it looks like M96/0400114453. The first 1 might not be a 1. It may be an upper case i or a lower case L.


Any help appreciated. Thanks,

Usually if it is a factory replacement engine it will have an AT in the engine number such as M96/04ATXXXXXXX.

It could be an engine from a donor vehicle.  See chart:

Here is my engine number for a 99 C2 with a manufactured date of 7/98 (thus my car has an engine made in 98).  So from your description M96/04, from Model Year 2001, 661 should be the next sequence, and the last five digits are the engine serial numbers, ranging from 00501 to 60000.  Yours is 14453.

Thank you for the information and help Joe. I'll go look again and verify the sequence after the 04. I took a so-so pic and it looks like 001 rather than 661 but I'll verify and try to get a good pic.
