'M' (Mehrausstattung) Number

Please find below a list of 'M' Numbers or Factory fitted options.  With production changes, some numbers became standard equipment, therefore the old 'M' number was reused for another option.  This is not a complete list, but is accurate to the best of our knowledge.  If you know of any corrections or missing numbers and descriptions, please let us know, we would very much like to hear from you.
