Mercedes-Benz A-Class — 电动转向
A-Class W177 EPS
W177 A-Class EPS uses a column-assist design — the electric motor is on the steering column rather than the rack. This design is lighter but more sensitive to vibration and water ingress. Fault codes B1120x (torque sensor) and C1511x (column motor) are the most common in Malaysia. XENTRY codes the replacement module.
