These were taken in portugal whilst on holiday! visited a dealer to see what the fox was like, and this was parked-up next to it! Was around the £12000 mark i think!

This is copied directly from a Vw Self Study Book that i got from work!

The 085 electronic manual gearbox was developed specially for the Lupo 3L and is operated by means

of an electronic gate selector lever. The development goal was to reduce fuel consumption.

This gearbox is based on conventional manual gearbox 085 which was revised to incorporate several

weight-saving measures.

To save weight:

- the shafts were drilled hollow

- the crown wheel was drilled

- the 5th gear is spoked

- the cheeks of the gear wheels were

recessed to make them lighter

- oil capacity was reduced by 0.2 litres while

maintaining

the same oil level by modifying the housing

Why a manual gearbox?

A manual gearbox has the following advantages

over an automatic gearbox:

- it is lighter, and

- it is more efficient

A manual gearbox with the characteristics of

an automatic gearbox

There is no clutch pedal. The manual gearbox is

operated automatically via a hydraulic selector

lever.

A control unit decides what gear is to be

engaged by means of the selector. As a result,

the engine operates in the optimal torque range

with regard to fuel economy.

Despite having the characteristics of an

automatic gearbox, the manual gearbox still

provides a choice of automatic or manual

gear-changing.

The manual gear-changing mechanism is the

same as in the Tiptronic.

The ´Stop´ position is not equivalent to the ´Park´ position

in an automatic gearbox. It is also necessary to apply the

handbrake. If the handbrake is not applied, a warning lamp

on the dash panel will flash for up to 5 minutes.

The driver can move the electronic gate selector lever into two

selector gates.

The gear change system

Upshifts

Middle position

Downshifts

To put the vehicle in reverse, press the Lock

button at the head of the gate selector lever

and the brake.

In the neutral position, it is possible to start the

engine when the driver's door is closed and the

brake is pressed at the same time.

In this position, gears are engaged

automatically.

In Economy mode, the stop/start function is

deactivated and the vehicle runs very

economically.

The engine is shut down automatically when the

vehicle is stationary and first gear is selected.

The can be started as soon as the driver's door is

closed and the brake pedal is pressed.

Automatic gearshifts Manual gearshifts

Even in Economy mode, the driver

can still utilise the engine's full power

by means of a kickdown function.

In Tiptronic mode, each gear is engaged

individually.

System design

The electronic manual gearbox comprises three main elements:

● the electrics

● the hydraulics, and

● the mechanicals

Electronic manual gearbox 085

The electrics

comprise sensors, actuators and the gearbox control unit. The control unit can recognise the actual state

of the system, e.g. what gear is currently engaged, from the signals which the sensors generate.

The input signals are processed in the gearbox control unit. The output signals for activating the

actuators are then calculated, e.g. for a gearshift operation.

The components the electrical system are:

- The electronic gate selector lever

A single potentiometer and three micro-switches on the gate selector lever

determine the position of the selector lever and transmit this information to the

gearbox control unit.

- The electronic accelerator pedal

transmits the current position of the accelerator pedal to the engine control unit.

The engine control unit then transmits a corresponding signal along the CAN

databus to the gearbox control unit.

- Potentiometer on selector and clutch actuator

One potentiometer recognises the selector gate position.

The second potentiometer recognises the gear row, e.g. 3rd or 4th gear.

The potentiometer on the clutch actuator recognises the current clutch position.

- The gearbox control unit

calculates the optimal gear position on the basis of

this information and activates the gearshift operation.

- An electro-hydraulic valve for the clutch actuator

is activated when the clutch is activated via the hydraulics.

- Four electro-hydraulic valves on the selector lever

admit the system pressure to the hydraulic piston in the gear

selector depending on requirements and activate a gear operation.

The hydraulics

The system utilises the hydraulics to execute the

necessary movements, e.g. clutch engagement/

disengagement or gearshift operations

The components the hydraulics are:

- A hydraulic pump and pressure

accumulator

generates the system pressure which is

required in order to be able to perform

gearshifts and operate the clutch.

The pressure accumulator keeps sufficient oil

and pressure in reserve to allow a quick

response.

- A clutch actuator

engages and disengages the clutch during

gearshift operations.

- A selector lever

moves the selector shaft via hydraulic pistons.

The mechanicals

are the same as in manual gearbox 085

The individual gears are engaged via

the selector shaft:

- The selector gate is selected

through rotation of the selector shaft

- A gear is selected through backwards and

forwards movements of the selector shaft.
