Audi A8 Power Steering Malaysia
D4: electro-hydraulic (EHPS) or fully electric EPS. D5: fully electric EPS with active rear steering. EPS rack with active rear steering: RM 4,000–8,000. VCDS steering angle sensor reset after any rack work. Active rear steering (D5): calibration required after any rear suspension work.

A8 Power Steering
- EPS + rear-wheel steering standard — both electric, no hydraulic fluid
- Rear-wheel steering actuator fault: VCDS coding + calibration required; RM 3,000–5,500
Audi EPS — No Fluid, But Maintenance Exists
The A8 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 VCDS coding if the EPS unit is replaced. Common EPS symptoms in Malaysia: groaning or whining on full lock in car parks (especially in heat), variable steering weight at highway speed (usually an EPS adaptation issue), or a steering warning light. VCDS can read EPS torque sensor data and motor current draw to diagnose early faults.
