slow or jerky gear changes, jolts when accelerating, unexpected return to neutral (N), unexpected switch to manual mode, engine will not start, automatic gearbox warning light on, gearbox stuck in limp mode.

DF005, DF078.

Meaning:

• DF005: oil pressure sensor circuit.
• DF078 / P0944: hydraulic control (pressure too low, pump fault, loss of pressure or accumulator fault).

Full list: Quickshift fault codes (DF, DTC and P-code).

Pressure sensor failure is rare. An oil pressure sensor circuit code (DF005: short circuit or open circuit) is not enough to condemn it: first check the accumulator and the electric pump, which are often at fault even with this code.

Only a diagnostic tool that shows the live pressure can settle it: the pump should start at around 40 bar and stop at around 50 bar. If the pump runs normally but the displayed pressure stays low, the sensor is at fault.

Guide with video: diagnose the gearbox in 8 seconds.
