Electric Pump Opel Vivaro Easytronic Techshift

Opel Vivaro, 2001-2014, 1.9 CDTI, 2.0 CDTI, 2.5 CDTI · Opel Movano, 2003-2016, 2.5 CDTI, 2.3 CDTI.

Petrol, diesel, Twingo 1: the Quickshift parts compatibility guide.

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).

• You can drive and the gears engage? The electric pump works: look at the accumulator instead.
• Direct test: power the electric pump with 12 V directly from the battery, using 2 wires. If it does not run, its motor is dead.
• It runs, then stops: the pressure builds up, it works. With a diagnostic tool, it should start at around 40 bar and stop at around 50 bar.
• It runs without ever stopping: either it no longer builds up pressure, or its control relay is stuck (code DF065, pump relay circuit).
• It runs on the battery but never switches on in the car: the control relay or the pressure sensor is at fault. A diagnostic tool that reads the pressure will tell you which.

Guide with video: diagnose the gearbox in 8 seconds.

• Robot oil — essential: replacing the electric pump requires topping up the oil level; without it the job cannot be completed.
• Opel Easytronic Techshift pressure sensor — to be checked in the event of a pressure fault (DF078)

Supplied complete with its pump: the electric pump fits directly, with no part to transfer from the old one.

Tools: 10 mm socket, 13 mm open-ended spanner, Torx T30, large syringe, drip tray.

1. Empty the reservoir with the syringe and place the drip tray under the electric pump.
2. Depending on the vehicle, remove the driver's side headlight (10 mm socket): the electric pump comes out more easily that way.
3. Loosen the rigid pipe nut (13 mm spanner) and unplug the connector.
4. Remove the 2 upper T30 screws, then lever at the top with a large screwdriver to free the lower fixing. Take the assembly out.
5. Fit the new electric pump, refit the upper screws, tighten the pipe with the 13 mm spanner and plug the connector back in.
6. Oil level, cold: 38 mm above the reservoir joint. With the ignition on, it drops to the joint.

No bleeding or reprogramming: the air bubbles rise by themselves the first time the ignition is switched on.

As the accumulator works together with the electric pump, these two parts have the same level of wear: we strongly recommend replacing them at the same time, along with the oil (see repair kit).
