Steering

Steering-angle sensor

Reports steering position for vehicle-control systems.

Where it sits

At the column or within an associated steering sensor assembly.

How it works

The controller uses angular position and plausibility information alongside vehicle-motion data.

Think of it as

A direction dial reporting where the driver points.

Symptoms when it fails

DSC or steering warnings can involve calibration, wiring or other related sensors.

Lifespan

Joints and boots are inspected for play, damage and leakage; electrical assistance has no universal preventive replacement interval.

Repair cost

A tie-rod or boot service differs from a complete assisted rack. Alignment and electronic calibration may add work.

The BMW angle

BMW stability control uses steering intent together with actual vehicle motion rather than steering angle alone.

Used in

BMW steering systems as fitted; assistance type and rear-steering availability depend on chassis.
