4 Series Power Steering
- All 4 Series use electric power steering (EPS) — no fluid to change

- EPS failure (rare before 120,000 km): RM 1,800–3,000 to repair
Electric Power Steering — No Fluid to Ignore
The 4 Series uses electric power steering (EPS) — there is no hydraulic fluid to check or change. However, EPS is not maintenance-free: the steering column bearing and EPS motor are wear items, and the system requires correct coding to the vehicle's VIN if the EPS unit is replaced. Common EPS symptoms in Malaysia: groan or whine on full lock in car parks, variable steering weight at highway speed (usually an EPS adaptation issue), or a steering warning light. ISTA can read EPS torque sensor data and motor current draw.
