'M' Code Optional Extras for the Type 4

Volkswagen maintained a list of options that were available when a new car was built. The codes were options or standard equipment in certain markets. These codes were called 'M' Codes.

This collection was taken from a dealer parts manual I have that dates to about 1974, but before production ended.

If you notice that I am missing some information, please feel free to email me.
