Porsche equipment codes
Standard equipment build codes, option codes and Exclusive options
Please note: paint and interior color codes are not covered with this research work
Every Porsche leaves the factory with a list of standard and optional equipment. Standard equipment is described by build codes and optional equipment by option codes. The codes are three or four character strings of numbers and letters. Back in the old days, all the codes started with an M and they were called as the M-codes. Nowadays they start with an I. Please note that the sticker in the service book or on the body never includes all the codes related to the car. It is a bit of a mystery why some codes are printed there and some are not.
It is important to understand that the code descriptions depend on the model and the model year. If you see an option code list somewhere that doesn't tell for which model and model year it is, then it is not a quality source for decoding the codes of your Porsche.
