iStep update: engine, gearbox, traction, fuel pump, steering, chassis, suspension
Updates your car's software version and iStep level. BMW revises its software over time, and updates can fix bugs or issues and even improve overall performance and fuel consumption.
Most cars never get an update, because they never visit a dealer for repairs, warranty work or recalls, which is when BMW would normally do it. Like a phone that's never updated, the car won't perform at its full potential.
We generally update engine, gearbox, traction control, fuel pump, steering, chassis and suspension software, and more.
