What are the reasons for the failure of the automatic steering wheel lifting in the BMW 5 Series?

BMW 5 Series steering wheel automatic lifting failure reasons are: 1. Excessive wear of the power steering pump; 2. Slippage of the power steering pump belt; 3. Failure of the steering valve; 4. Circuit failure or connector failure, etc. If the steering wheel adjustment fails, it may cause loss of control, so it is recommended to go to a 4S store for inspection and repair as soon as possible. Taking the BMW 5 Series 2021 modified 525Li Luxury Package as an example: The manufacturer of this car is BMW Brilliance, the level is medium and large car, the energy type is gasoline, the transmission is 8-speed automatic manual, and the body type is 4-door 5-seater sedan.

I've been driving a BMW 5 Series for over a decade and encountered issues with the automatic steering wheel height adjustment malfunction. There are several common causes. Motor failure is the primary culprit – the lift motor wears out over time, leading to gear slippage or jamming, resulting in unresponsive adjustment. Wiring issues shouldn't be overlooked either, such as harness aging, short circuits, or poor contact, possibly due to a loose or corroded connector. The position sensor failure is also critical; located at the base of the steering wheel, dust accumulation or damage can cause the system to inaccurately detect positions, preventing automatic adjustment. Software glitches in the control module are another factor – BMW's iDrive system occasionally has bugs, and sometimes restarting the vehicle can resolve it. Additionally, a blown fuse cutting off power will cause the entire system to stop working. To prevent worsening the issue, avoid frequent adjustments and conduct regular inspections, as prolonged problems can compromise driving comfort. It's best to visit a professional repair shop early.

The automatic steering wheel adjustment malfunctioned. I believe the mechanical components are most prone to issues—dust clogging the adjustment tracks or dried-up lubricant can cause it to jam. On the electrical control side, broken wires or blown fuses can cut power directly. Sensor failures are also common, especially inaccuracies after getting damp on rainy days. System software glitches might be fixed with update patches. I suggest first checking the fuse box and trying a new fuse. If that doesn’t work, see if the motor overheated and burned out. Avoid operating the adjustment on bumpy roads to reduce wear. This issue needs prompt attention—otherwise, you can’t adjust the steering on long trips, which is incredibly annoying. A simple fix now can save big money later.

I've encountered this issue before, and the core problem lies in the electronic control or sensors. If the position sensor is dirty or malfunctioning, the system position becomes chaotic, leading to lifting failure. Control module software errors are often caused by incompatible upgrades, and a power cycle might restore functionality. Damage to the motor drive circuit can also cause signal errors. Check if the connectors are tight, and use an OBD tool to diagnose fault codes if necessary. Avoid self-disassembly as it carries significant risks. Quick repairs can restore the driving experience.
