What are the steps to make BMW steering lighter?

The power source for hydraulic power steering is the engine. When driving, avoid holding the steering wheel at full lock for extended periods. If the steering assist pump oil pressure is too low, it can damage the pump and cause the steering to become heavier. When tire pressure is too low, the steering will feel heavier. It is recommended to check the tire pressure.
Adjusting steering from heavy to light is quite common. Let me explain from a practical user's perspective. When you find the steering wheel too heavy, don't rush to make changes. It's best to connect a diagnostic tool to read the fault codes first. For BMW vehicles, OBD devices are typically used to scan steering system errors. If no issues are found, update the vehicle's software—sometimes an iDrive upgrade can adjust the power steering assistance. For hardware issues, such as aging power steering motors, replacement or calibration is necessary. Personally, I always back up data before making adjustments. The general steps include: diagnosing errors, updating software, and testing after part replacement. It's safer to have the entire process handled by a professional shop, as they have specialized tools and can avoid operational errors that might compromise safety. After adjustments, a test drive is essential to confirm the steering is both lighter and stable—otherwise, it could be dangerous at high speeds. Regular maintenance of the steering system can also prevent this issue.
