Many BMW owners enjoy the precision, comfort, and dynamic handling that come with the brand’s advanced steering technology. Among these innovations is Integral Active Steering (IAS), a feature designed to enhance the driving experience by improving agility at lower speeds and stability at higher speeds. This system works seamlessly in the background to make city driving easier, high-speed cruising more secure, and manoeuvring in tight spaces far more manageable. It is one of the many reasons drivers across the USA value the engineering excellence found in BMW vehicles.
However, like any advanced technology that relies on both mechanical components and electronic systems, Integral Active Steering can occasionally encounter problems. If you drive a BMW equipped with this system and begin to notice unusual steering behaviour, dashboard warning lights, or error messages, you may be dealing with an issue related to IAS. Addressing these problems early on can save you from costly repairs and keep your BMW running at peak performance. In this guide, we explain the most common issues, symptoms to watch for, and how to resolve them with the help of Automanspareparts.com, your trusted USA-based source for high-quality BMW parts.
What is BMW Integral Active Steering?
Integral Active Steering adjusts the front steering ratio and adds rear-wheel steering to provide greater agility at low speeds and improved stability at high speeds. The system also works with various driver assistance technologies, helping to enhance the driving experience.
By controlling the angle of both the front and rear wheels, IAS allows for tighter turning circles, better cornering, and smoother lane changes. The system operates through sensors, electronic controls, and electric motors making it both a mechanical and electronic component of your BMW.
