What this code means
Gear Shift Lock Solenoid Circuit / Open.
P0928 is a generic code: it means the same thing on every make. P0928 belongs to family P09xx — Transmission and controls. Its page explains how to read a code and groups all its codes by part.
Type of fault
The control unit no longer sees continuity in this control circuit: a broken wire, an unplugged connector, or an open winding in the component. A multimeter checks both the component's resistance and the continuity of the wires.
Automated gearbox actuators
Automated manual gearboxes are manual gearboxes whose clutch and gear changes are operated by actuators, hydraulic or electric. Sensors measure the clutch position and the selector position, and the control unit learns these positions.
What you notice
Jerky starts, a slipping clutch, a gear that will not engage, a gearbox stuck in neutral.
How to check it
Check the hydraulic fluid level if the system uses one, the actuators' connectors and the battery voltage, since these gearboxes are sensitive to it. After any repair or a battery disconnection, a relearn of the positions with a suitable tool is often required.
What to do
Have it checked this week. The car remains usable, but the fault will not clear itself and will fail the roadworthiness test.
