Developed on the basis of the Polo, the Fox has inherited the best that Volkswagen can offer in terms of safety, comfort and technology for compact automobiles. São Bernado do Campo plant, Anchieta The world’s second largest Volkswagen plant (the largest is in Wolfsburg, Germany) was opened on 18 November 1959. It has a total floor space of 1,984,811 m2 and the buildings cover an area of 1,123,948 m2. The daily production capacity is 1,400 cars. The main activities at the plant are press moulding, frame and body assembly, painting, final assembly and the production of engines as well as research, product planning and development. São José dos Pinhais plant, Curitiba The São José dos Pinhais plant features a new kind of layout for the group:S349_209S349_208S349_005The areas of frame construction, painting and final assembly run together into a communication centre. The building where the administration offices are located is triangular. The flow of information is therefore faster and constant quality improvement is supported. The Fox 2006 is built at both Brazilian plants.S349_007S349_0065In BriefFox 2006The Fox 2006 is based on the Polo 2002 platform, although the Fox is 15mm taller than the Polo.

The design and structure ensure good crash safety. The body is partly galvanised and has a 12-year guarantee against internal corrosion.Longitudinal memberS349_013Longitudinal member The underbody features a frame structure. The longitudinal member is made from sheet metal with increasing thickness. The increased capability to absorb bumps provided by this system is called progressive absorption. The protection of occupants in the cockpit is thus maximised.Bumper covers front and rear The bumper covers at the front and rear can absorb an impact energy at up to 4 km/h without damage. Higher collision speeds up to around 15 km/h are absorbed by impact members without the longitudinal members being deformed. The longitudinal members are only deformed in severe collisions.Front impact member S349_21510B-pillar reinforcementS349_017 S349_212 Sill reinforcement Side impact memberSide impact protectionSeat cross memberIn a side collision, the reinforced B-pillars, the sturdy sills and the inside door panel, which is almost closed, minimise deformation of the passenger cell. The side impact member, the door gutter reinforcement and the padding between them provide an ideal barrier against the impact force. The padding is the side protection cushioning in the doors.Rear impact member S349_21411BodySeatsThe Fox has been designed as a 4-seater. The front seats can be optionally equipped with the easy-entry system, the rear seat comes as a single bench as standard or optionally split and folding.Rear seat bench The rear bench is made up of two seats with a storage bin and cup holder in the middle.S349_216Front seats The front seats in the Fox are available with easy-entry and manual memory function upon request.Driver’s seatLever for easy-entry and for folding the backrest forwardsBackrest tilt adjustmentSeat length adjustment S349_019 Drawer under driver’s seatSeat height adjustment12Easy-entry The easy-entry system makes it easier to access the rear seats. When you want to climb into the back seat, the backrest of the front seat is unlocked as usual and folded forward. At the same time, the front seat can be pushed forward. This creates more space so you can climb into the car easily.Function Folding the front seat backrest forward activates the memory module on the seat rail.S349_341S349_342The activated memory module unlocks the length adjustment of the front seat allowing the front seat to be pushed forward. At the same time, the memory function is triggered. Using this function, the memory module mechanically records a change to the position of the front seat so that the starting position of the front seat is stored mechanically in the memory module.S349_343To return the front seat to its initial position, the front seat needs to be pushed back with the backrest folded forward. Once the front seat has returned to its initial position, the memory module triggers the memory function and the length adjustment is locked. Once the backrest has been folded back, the memory module locks the length adjustment of the front seat.S349_344If the backrest is folded back before it reaches the initial position, only the length adjustment is locked. The memory function is kept until the initial position is reached.13BodyRear benchThe rear bench is made up of two seats with a storage facility and cup holder in the middle. The rear seat bench can be moved completely (optional) and folded up against the front seats (tipped) to make the boot larger. The seat backrests can be folded down separately.Securing hooks The red hook on the back of the rear seat bench hooks into the front seat head restraint. It prevents the rear seat bench falling back.Securing hooksMoving the rear seat bench lengthways (optional) The rear seat bench slides lengthways. A toothed rail with a catch locks the rear bench so it cannot be moved back and forth. You release the lock by lowering it with the lever at the front of the seat base. Another handle can be accessed from the boot.Handle for lengthways adjustmentLockS349_225A full-width, one-piece rear seat bench is also available. Both rear bench systems have Isofix anchor points for securing child seats as standard.14Folding down the back rest Both rear seats can be unlocked and folded down separately. Two loop handles have been provided at the front to help you fold the seat.Loop handlesHandle for folding down the backrest and rear benchS349_297The backrests can be released using the lever for folding down the backrest and rear bench in the boot.Lever for moving the rear bench lengthwaysFolding down the rear seat bench The rear seat bench can only be folded down completely once it has been pushed back as far as possible. In this position, the lever presses against the release pin when the handle for folding down the backrest and rear seat bench is moved. This opens the catch in the floor lock. The backrests are unlocked at the same time and the rear seat bench can be folded over.LeverRelease pinS349_224S349_226The backrest is locked by four teeth at the same time to distribute the force.15Occupant ProtectionAirbag systemThe Fox is equipped with the proven occupant protection systems, the airbag system and the restraint system.The complete airbag system includes: - Driver airbag - Front passenger airbag - Optional side airbags in frontOptional front passenger side airbagFront passenger front airbag moduleSide airbag crash sensor in cockpit under driver’s and front passenger seat.Airbag control unit with crash sensor16Restraint systemThe belt system includes: - Three-point seat belts with pyrotechnic belt tensioners for driver and front passenger - Three-point seat belts without belt tensioners on the rear seat benchThree-point seat belts without belt tensioners for the rear seat benchOptional driver side airbagS349_231Driver front airbag moduleThe restraint system is uses three-point seat belts with pyrotechnic belt tensioners and belt pressure limiters for the driver’s and front passenger seat.17EnginesOverview of engines and gearbox1.2l 40kW petrol engineS349_0331.4l 55kW petrol engineO2T 5-speed manual gearboxS349_034S349_0381.4l 51kW diesel engineS349_0361802T 5-speed manual gearboxThe 02T gearbox used in the 2002 model year Polo is installed in the Fox. The maximum torque to be transferred by this gearbox is 200Nm. The complete gearbox transmission is configured for the respective engine version using different gear ratios and different transmission ratios for the axle drives. The gearbox is assigned to the engine via the gearbox code.S349_038S349_239Gear changes The gears are changed via a selector cable and a shift cable. Thanks to these cables, the rocking movement of the engine acts only slightly on the gearstick. This allows you to select gears more precisely.Further information can be found in self-study programme no. 237, which contains details on the design and operation of this gearbox.19Engines1.2l/-40 kW petrol engineThe 1.2l 40kW petrol has been taken from the 2002 model year Polo without any modifications.Technical features 2-valve technology Chain-driven valve control Crankshaft drive with balancer shaft Oil filter arranged standing Single-spark ignition coils with integrated output stagesS349_370You will find further information on this engine in self-study programme no. 260 The 1.2l 3-cylinder petrol engines.Technical dataPower and torque development graphNm kW 60 55 50 45 40 35 30 25 20 15 10 1000 2000 Power [kW] Torque [Nm] 3000 4000 5000 rpmEngine code Type Capacity [cm3] Bore [mm] Stroke [mm] Valves per cylinder Compression ratio Maximum output Maximum torque Engine management FuelBMD 3-cylinder in-line engine 1198 76.5 86.9 2 10.3 : 1 4kW at 4750rpm 108Nm at 3000rpm Simos 3PG Super unleaded RON 95 (normal unleaded at RON 91 with reduction in performance) Catalytic converter, Lambda control with two probes EU4170 160 150 140 130 120 110 100Exhaust gas treatment90 80 70Emissions standardS349_032201.4l/55 kW petrol engineThe 1.4l 55kW petrol engine featured in the Fox is an all-new engine.

It has a volume of 50l. The Fox has a galvanised steel sheet tank. Galvanising the steel sheet improves the corrosion resistance compared with conventional metal tanks.Quick-fastening couplings are used for easier assembly of the fuel lines.Quick-fastening couplingS349_293 Fuel tank Activated charcoal filter Reservoir S349_290The activated charcoal filter is located in the rear right wheel housing. All petrol fuel systems are equipped with an activated charcoal filter to meet the environmental legislation. The activated charcoal container collects the fuel vapours produced during operation and then delivers them to the engine for combustion later on.Fuel pump The fuel pump is secured with a bayonet ring.S349_29223EnginesCombination valve The combination valve has the task of preheating and cooling the fuel. It splits the fuel system into a vehicle circulation system and an engine circulation system. The combination valve is mounted on the coolant expansion tank in the engine compartment. Fuel preheating prevents the fuel filter being blocked in the winter by paraffin that separates from the diesel fuel at low temperatures. Fuel cooling protects the fuel tank as well as the fuel gauge sender by preventing a return of high-temperature fuel. The fuel is warmed due to the high pressure that is built up in the unit injectors.Vehicle circulation system The vehicle circulation system is made up of the fuel tank with the fuel pump and pressure control valve as well as the fuel return.Engine circulation system The engine circulation system includes the fuel temperature sender, the injection system, the tandem pump, the fuel filter and the fuel supply line.Combination valveFuel temperature senderTandem pump Pressure control valve Fuel pump Fuel filterS349_364 Injection system TankMixing the cold and warm fuel in the combination valve increases the temperature of the returned fuel. This also increases the temperature and pressure in the fuel tank. The threshold value for opening the pressure control valve in the fuel tank has therefore been raised from 0.5 bar to 0.8 bar.24Function The vehicle return is closed by the plunger in the combination valve during a cold start. Warm fuel flowing back from the engine return is mixed in the combination valve with cold fuel from the vehicle supply line and is returned to the engine. Preheating the fuel in this way prevents the separation of paraffin and thus fuel filter blockages.Combination valve closedPlungerEngine returnVehicle returnEngine supplyVehicle supplyS349_361 HousingAs the engine temperature increases, the fuel temperature in the engine return also increases. This heats the plunger with the wax element in the combination valve. The wax element then expands and pushes the piston upwards against the spring.Engine returnSpring Wax element S349_362Combination valve openOnce the operating temperature has been reached, the combination valve opens the engine circulation system to the vehicle circulation system. The warm fuel from the engine supply line mixed with cold fuel from the vehicle supply can then flow back to the fuel tank. Mixing with cold fuel in the combination valve prevents the fuel in the fuel tank being heated above a limit temperature.S349_363Vehicle return25ChassisAxlesFront axle The front axle of the Fox is the same as the one used in the 2002 model year Polo. McPherson struts are used as on the Polo.Rear axle The Fox has either a rear axle with tube profiles like the 2002 model year Polo and a rear axle with a Vprofile cross member. The tube profile is used in the versions of the Fox with 1.4l 55 kW petrol engine and 1.4l 51 kW TDI engine. The V-profile is used in the Fox with 1.2l 40 kW petrol engine.Rear axle with tube profileS349_300SteeringS349_044The hydraulic pump for the electro-hydraulic power steering is driven by an electric motor. The power steering is thus not dependent on the operating state of the vehicle engine and the energy supplied for steering assistance is adjusted to requirements. This ensures an improvement in comfort when manoeuvring and helps save fuel.Further information on the ESP electronic stabilisation programme can be found in self-study programme 204.26BrakesThe brake system used in the Fox is split diagonally into two circuits. Two different brake systems are available. ABS (anti-lock brake system) is fitted in the European version of the Fox as standard and ESP (electronic stabilisation programme) is available as an option.S349_043Anti-lock brake system The brake servo with brake master cylinder is located separately from the ABS/ESP hydraulic unit in both systems. The hydraulic unit is located on the left next to the strut tower. The Fox uses the anti-lock brake system 8.0 from Bosch. It is the same system as used in the 2006 model year Polo.Rear wheel drum brakes Drum brakes are used on the rear axle. The brakes have a diameter of 200 mm and are 40 mm wide.S349_046 S349_042Front wheel disc brakes Disc brakes are used on the front axle. The ventilated brake discs are 22mm thick and 256mm in diameter. On cars without power steering, the brake discs are 18 mm thick and 239 mm in diameter.S349_04527Electrical SystemOnboard supplyThe onboard supply is decentralised. The most important components are shown here.A-pillar coupling station The coupling station on the A-pillar is used to connect or disconnect electrical components in the doors from the rest of the onboard supply system.Compact connector The compact connector is a coupling station on the bulkhead for connecting/disconnecting the onboard supply components in the engine compartment and passenger compartment.Main fuse carrier The main fuses are all located in the main fuse carrier on the battery lid and are easy to access.S349_087Fuse holder The fuse holder is made up of two holders.Onboard supply control unit This unit takes care of functions that were previously performed using separate relays (e.g. turn signal relay). It monitors the supply of power to consumers and vehicle components outside the CAN systems (e.g. switches/fuses).Relay carrier The relay carrier is used to hold the relay for basic and special equipment.28Exterior LightsHeadlights The headlights have clear covers made from plastic. The headlight unit has a combined reflector for dipped beam and main beam lights (H4 bulb). The side lights (W5W) and the turn signal (PY21W).S349_047 Turn signals Side light Dipped beam and main beam (H4)Fog light The fog lights are integrated in the bumper. An H3 bulb is used for the fog lights.S349_049 Adjusting screwTaillight One screw, accessed in the boot, needs to be removed when you change the bulbs in the taillight. A two-filament bulb (P21/5W) is used in the taillight/ brake light. The bulb for the turn signal is a PY21W, which has been coloured yellow. The rear fog light (P21W) is only installed on the left-hand side. The reversing lights also use P21W bulbs.Taillight/ brake light Reversing light Turn signalRear fog lightS349_04829Electrical SystemOverview of control unitsThe following diagram shows the positions of the control units in the Fox.Convenience system central control unitDash panel insertOnboard supply gatewayRadio Climatic control unitControl unit of ABS Bosch 8.0S349_088Location of engine control units - Simos 3PD* - Bosch EDC 15P* Engine control unit Magneti Marelli 4EV*Airbag control unitPower steering control unit*The engine control unit used depends on the engine.30Dash panel insertThe dash panel insert has been newly developed for the Fox and is based on the group dash panel insert.

The convenience close function is started after approx. 2 seconds. You need to hold the door lock cylinder until the windows have closed completely. The convenience close function will be interrupted if a window switch is pressed or the EFL roll-back feature is triggered.Convenience open function for windows If you turn the key clockwise in the door lock cylinder and hold it in cars with power windows, the convenience open function will open all windows after 2 seconds. You need to deactivate the anti-theft alarm with the remote control beforehand.S349_329S349_328Excessive force limitation (EFL) The excessive force limitation reduces the risk of injury from the power windows.S349_324 S349_332Command 1st upwards runEffect When the window is jammed, the excessive force limitation reacts and the window is reversed. The window rolls back to create an opening of at least 200mm.2nd upwards run 3rd upwards runWhen the window is jammed again, it will not reverse. The window stops in that position.The upwards movement is carried out without EFL. The full power of the motor is available for the whole path. The window can be closed even though it may run slowly.The three commands each have to occur within 10 seconds otherwise the electronics will switch back to normal window operation.35Convenience and Safety ElectronicsAnti-theft alarm with interior monitoring sensorAnti-theft alarm The anti-theft alarm monitors the areas Doors Bonnet Tailgate Ignition The anti-theft alarm is activated within 30 seconds after the doors are locked. The anti-theft alarm can only be deactivated from the outside using the remote control.Special features The system is completely secure against false alarms caused by: - Objects hitting the roof or the windows - Air movement caused by wind or passing vehicles, temperature fluctuations, for example, when the car is heated up by direct sunlight and - noises of all kinds (for example, sirens, horns and bells).Convenience system central control unitAlarm hornAlarm horn The alarm is signalled acoustically via the anti-theft alarm horn and optically via the turn signals.If, for example, the bonnet is opened, an alarm is triggered immediately. The alarm is stopped when the ignition is switched on or the remote control is pressed.36Interior monitoring The interior monitoring works as an ultrasound monitoring system. It is only used in conjunction with the anti-theft alarm.Interior light with sensor for interior monitoringInterior lightS349_356S349_357Interior light with interior monitoring without sunroofInterior light with interior monitoring with sunroofInterior monitoring sensor buttons On vehicles with a sunroof, the button with which the interior monitoring system can be temporarily deactivated is located on the B-pillar.S349_055 S349_054On vehicles without a sunroof, the button for temporarily deactivating the interior monitoring system is located on the interior light.S349_35837Convenience and Safety ElectronicsConvenience system functional diagramPositive Negative Input signal Output signal Communications line CAN data busInOutS349_314S349_315J519E48E43L78Z4Z5V17V149V25V150S349_310E43 E48 J519 L78 V17 V25 V149 V150 Z4 Z5 sideMirror adjustment switch Mirror adjustment change-over switch Onboard supply control unit Mirror adjustment switch illumination bulb Driver side mirror adjustment motor Front passenger side mirror adjustment Driver side mirror adjustment motor Front passenger side mirror adjustment motor Heated exterior mirror on driver side Heated exterior mirror on front passenger38J519 J533Convenience CAN data bus W J393KF2F3L118E183S349_311E183 F2 F3 J393 J519 J533 K L118 WInterior monitoring switch Driver door contact switch Front passenger door contact switch Convenience system central control unit Onboard supply control unit Data bus diagnostic interface Communications line for diagnosis Deactivation of interior monitoring system switch illumination bulb Front interior light39Convenience and Safety ElectronicsTerminal 301Terminal 30 aJ519 W3 G209 V147 V148 F120J393E150L99E107L53E40E81L53S349_312Front left window regulator switch Front right window regulator switch Window regulator switch in front passenger door E150 Driver side interior locking switch F120 Anti-theft alarm and vermin repellent system contact switch G209 Anti-theft alarm ultrasonic sensor J393 Convenience system central control unit J519 Onboard supply control unit L53 Window regulator switch illumination bulb L99 Interior lock switch illumination bulb E40 E81 E107V147 V148 W3 1Driver side window regulator motor Front passenger side window regulator motor Luggage compartment light Terminal 86 s40Terminal 30 a Terminal 31V139F5H8J393M27 F121 V162 V161S349_313F5 F121 H8 J393 M27 V139 V161 V162Luggage compartment light switch Driver door exterior handle switch for anti-theft alarm system Anti-theft alarm system horn Convenience system central control unit Left door warning lamp Rear lid release motor Driver door central locking deadlock function motor Front passenger door central locking deadlock function motor41Heating and Air ConditioningHeatingThe basic version of the Fox has a heating system with fresh air and recirculation mode. In comparison, the design of the housing is very similar. Depending on the equipment version, the housing is specially adapted for the heating or air-conditioning functions.Fresh-air flapS349_064Fresh-air and recirculation flap The fresh-air and recirculation flap is adjusted by an electric motor. Both flaps are adjusted independently via a common lever mechanism. The flap is automatically closed when the car reverses to avoid unpleasant smells.Recirculation flapDust and pollen filter S349_065 Temperature flapDust and pollen filter The dust and pollen filter has been integrated in the housing and is located between the fresh-air intake and the distribution system housing. The filter can be accessed from inside the vehicle and can be pulled downwards after the filter lid has been removed.42ClimaticIn addition to the heating, the Fox has a semi-automatic air-conditioning system with automatic temperature control (Climatic). While the interior temperature is regulated to the value set on the controller, the air distribution and the fan level is set manually.Fresh-air flapS349_062 Recirculation flapTemperature control according to your needs Two new components in the air-conditioning system allow you to set the temperature according to your needs: - Evaporator output temperature sender G263 - Externally controlled compressor with regulating valve N280 and integrated overload protection Controlling the temperature to suit your needs allows the energy consumption to be reduced and contributes to fuel savings.Auxiliary heater elementDust and pollen filterS349_063 Temperature flap Heat exchangerOther new features: - Functional improvements and controls adapted to the dash panel design - Flexible shafts for adjusting the flaps - Separate fresh-air and recirculation flap - Dust and pollen filter integrated in housing for the heating and air-conditioning system.43Radio systemRadio RCD 200The Radio RCD 200 has the following functions: CD drive Four speaker channels each with 20 Watts RDS FM/AM Europa radio (AM without LW) Control for an external 6-CD changer Telephone control (hands free) Speed-dependant volume control Self-diagnosis including speaker diagnosisS349_059If only front speakers are installed, the FADER function will be hidden automaticallyRadio RCD 200 The aerial system for the RCD200 radio is made up of a front windscreen aerial and the aerial amplifier in the aerial cable. The aerial amplifier is supplied with power (+12 volt) directly from the radio via the aerial cable. The earth connection is formed via the screw fastening the aerial amplifier to the body.Aerial amplifier (impedance transformer)S349_333Earth44ServiceDiagnosisThe Fox uses the VAS 5051 vehicle diagnosis, measuring and information system and the VAS 5052 vehicle diagnosis and service information system.The VAS 5051 vehicle diagnosis, measuring and information system has the familiar operating modes: Guided Fault Finding Vehicle Self-Diagnosis OBD (on-board diagnosis) Test InstrumentsVAS 5051The “Guided Fault Finding” operating mode checks all control units installed in the vehicle for fault entries and automatically compiles a system test plan from the results. In conjunction with ELSA information, for example, the circuit diagrams or repair guides, this mode guides you directly to the cause of the fault. In addition, you also have the option of compiling your own test plan. The function and component selection records the tests you select in the test plan. You can then work through the tests in any order during the diagnosis procedure. The “Vehicle Self-Diagnosis” mode can still be used, but there is no further ELSA information available. The “Guided Functions” operating mode is new. In this way, without a complete vehicle system test, you can quickly access general service functions, for example, adapting vehicle keys.S349_067The VAS 5052 also has the “Guided Fault Finding” and “Guided Functions” operating modes.It is used from the basis CD V06.00.00 and the Volkswagen brand CD V06.42.00.For more detailed information on the procedure and “Guided Fault Finding”, please refer to chapter 7 of the VAS 5051 operating manual.45Notes4647349© VOLKSWAGEN AG, Wolfsburg All rights and rights to make technical alterations reserved. 000.2811.63.20 Technical status 05/2005 Volkswagen Service Training VK-21 Brieffach 1995 38436 Wolfsburg❀ This paper was manufactured from pulp that was bleached without the use of chlorine.
