Mercedes-Benz GLA — 电动转向
GLA EPS — X156 and H247
X156 GLA and H247 GLA both use column-assist EPS. The higher ride height of the GLA means more steering column angle — this can accelerate wear on the upper torque sensor bearing. H247 GLA updated the column assembly but the fault pattern is similar. XENTRY diagnosis before any part replacement.
