"It is too early to say exactly what it will cost. We expect the final figure to be in the two digit million Euro range. The update only applies to Euro 5 cars. All BMW Group vehicles sold today are already Euro 6 standard and therefore no update is possible as these engines already achieve the best possible results," the spokesperson said.
According to BMW, Wednesday's meeting with German politicians was constructive.
"We are currently finalizing the operational aspects of the software update; it is too early to say when the upgrade will begin or how long it will take to upgrade the relevant BMW Group vehicles," the spokesperson said.
According to the statement of the German Automotive Authority (VDA), the owners will not incur the cost of the update, and neither the engine performance nor fuel consumption will be affected.
In July, German court backed the proposal of the Environmental Action Germany group to bar older diesel vehicles from the center of Stuttgart. Munich is reportedly also considering a similar ban.
