With the purchase of the Eisenach car factory end of 1928, BMW took over the license agreement with the Austin Motor Company, under which the Dixi 3/15 DA was further built. The enhanced BMW 3/15 PS was then with the sale beginning in July 1929, the first car of BMW, but a further under license from Austin. From the French car manufacturer Rosengart BMW secured the right to take over its contemporary exterior design and developed the model for a complete all-steel body on.
Under the direction of the chief engineer God Help Dürrwächter the first production car on March 22, 1929 in Berlin -Johannisthal arose. The chassis supplied the BMW factory in Eisenach; the sheet metal parts produced on the new presses at Ambi- Budd built BMW employees in a rented hall together right next to the Ambi- Budd plant to modern all-steel bodies. While in Berlin- Johannisthal production was stockpiled, BMW prepared in Eisenach the production of conventional bodies in the classical mixed construction according to the " system Weymann " before.
On 9 July 1929, the new BMW store opened in Berlin, at the same time was the press launch. From then on, the BMW 3/15 PS was available in two versions, sedan and touring cars at the BMW dealers.
Already in late 1929 broke the good sales numbers by the incipient global economic crisis. BMW took in 1930 outsourced production from Berlin- Johannisthal back to Eisenach. Despite the hard times of DA 2 was developed in 1931 to DA 4 with oscillating axle and enlarged body on. However, the axis of oscillation got to be too imprecise wheel control quickly in the criticism of art, and had to be repaired.
Production of the 3/15 was completed with the launch of the successor of 3/20 in March 1932; the 3/15 was but with and without oscillation axis to find by the end of 1932 in the price lists.
