Around 14,000 staff members are currently employed in Puebla; amongst other vehicles, they produce the New Beetle and the Jetta. These were joined by the new Golf Estate in 2007. In some markets, the Golf Estate will also be marketed under the name Jetta Sportwagen. The above will now also be joined by the Jetta 2011, which will replace the previous model.S468_0494… Modern clocked assembly lines …S468_048 S468_053At the plant in Puebla with its highly modern equipment, a consistently high quality standard is ensured. In Puebla, the engineers were thoroughly trained in both the preparation and development of the new Jetta and in the preparation of actual production. A high product quality is ensured by modern clocked assembly lines in combination with a corresponding modular production strategy.S468_054The plant is thus among Volkswagen’s leading production plants. The Jetta 2011 will be built on the production systems which are already in place for the Jetta’s previous model.5In BriefThe Jetta 2011The Jetta 2011 sets the standards in many areas of its class, e.g. in terms of: – – – – – – – Safety Design Quality Handling Ride comfort Spaciousness FunctionalityqSeat occupancy recognition on the front passenger seat* (capacitive principle)qNew headlight designqSide marker lamps integrated in the headlightsqOptional driver seat with 2 position settings (manual) *qOptimised front axle with subframe and wishbones made of steelqElectronic stabilisation programme ESP MK60*qAnti-lock brake system MK70qNew tyre pressure monitor*qHydraulic power steering or electromechanical power steering (depending on the model)6qOptionally equipped with the “Keyless Access” locking and start system – for starting with “Engine” start button*qAerial concept – radio aerials in the rear window, navigation system aerial (GPS) and aerial for satellite tuner (SAT) in the roof aerialqActuation of the central locking system also at the rear seats via switch at the end of the centre consoleS468_055qNew rear light designqOptional sound system*qRear axle as twist-beam rear axleqIncreased front and rear track widths ensure significantly better vehicle dynamicsqEquipped with heating*, with manual air conditioning* or with semi-automatic heating and “Climatic” air conditioner ** * for USA and Canada ** for Mexico7In BriefTechnical dataJetta 2011S468_056S468_057S468_058 The dimensions given in the pictures are in mm.Length Width Width with exterior mirrors Height Wheelbase4628–4644 mm* 1778 mm 1985–2020 mm* 1453 mm 2651 mmTrack width at front Track width at rear Kerb weight Permissible gross vehicle weight Drag coefficient1535 mm 1532 mm 1272–1464 kg* 1820–1950 kg* 0.3 Cd*may vary, depending on the model equipment8Interior dimensionsS468_059S468_061The dimensions given in the pictures are in mm.Front headroom Rear headroom Interior length Driver width at shoulder height Front passenger width at shoulder height1014 mm* 943 mm* 1797 mm 1401 mm 1362 mmTank capacity Luggage compartment volume55 litres 510 litres*may vary, depending on the model equipment9BodyBody structureThe body structure of the Jetta 2011 has been consistently developed – in particular in terms of the requirements concerning:q q q q qLightweight construction Vehicle safety Sportiness Comfort QualityS468_079A significant reduction in weight has been achieved compared to the previous model. At the same time, the new body structure also offers a high degree of crash safety and a superior body rigidity compared to the competition. This new weight reduction supports the efforts of the Volkswagen Group to reduce CO2 emissions.Lightweight constructionThe lightweight objectives were fulfilled due to:qq qOptimum use of ultra-high-strength and hot-formed steel Reduction of the steel thickness Sophisticated design according to optimised calculationThe generally accepted trend that “large and comfortable vehicles are heavyweights” has been convincingly disproved. The weight reduction measures can be split up into three groups.qThe main part of the reduction results from the extensive use of hot-formed parts in the floor structure, the B-pillar and the roof frame. Another important measure is the reduction in thickness of the material of body parts exposed to smaller loads, such as the body shell parts – without any loss of the performance characteristics. The third measure is the consistent implementation of the positive effects of weight reduction in the body design. For example, weight can be saved by clean profiles and minor reinforcements at the “correct points”.qq10Material grades and their distribution in the body structureStrength of the steel panels Percentage of steel panels according to strength (see legend above) 220 MPa 420 MPa 1000 MPa13%46%41%S468_062Laser solder jointWelding methodTo join the body components, the established spot welding method is generally used.Laser solderingLaser soldering is applied on the roof to join the side parts to the roof and on the luggage compartment lid at the vertical panel of the rear end.Laser solder joint S468_080 Luggage compartment lid - upper section Luggage compartment lid - bottom section11BodyBody rigidityWith its especially rigid body design, the body structure of the new Jetta 2011 meets the high demands in terms of acoustic and vibration performance. This has been achieved by:q qThe systematic design of the nodes and force transmission points Optimum use of the available installation space of the consistent three-part structure – the passenger compartment is thus enclosed by computer-optimised body profilesThe new Jetta Static torsional rigidity (Nm/°)CompetitorsS468_063Torsional frequency (Hz)The body structure of the Jetta 2011 is characterised by an outstanding static torsional rigidity – the same also applies to its dynamic rigidity. The Jetta 2011 is thus far superior to its competitors in this context. In particular, the acoustics, the vibration performance and the excellent ride comfort of the new Jetta benefit from this high body rigidity.12Crash-safe body designAn important focus of development work was that the measures for increasing the body rigidity always also ensure a high degree of crash safety. In combination with the lightweight design, a special mix of materials has been used. Materials with either a low or a high resistance to deformation are applied specifically to appropriate sections of the bodywork. Specially coordinated force transmission paths and energy-absorbing deformation zones were created in the body design. This ensures targeted force transmission in the event of a crash. The body has been designed in such a way as to ensure optimum force transmission in the event of front, side and rear impact.The two figures illustrate the transmission of force in the event of a front impact.S468_064S468_06513BodyFeaturesThe Jetta 2011 has a body with completely new outer contours that ideally meet market-specific requirements.Front seatsThe front seats are equipped with safety-optimised head restraints. 2-way lumbar support is available as an option.BonnetThe Bowden cable for opening the bonnet is installed in the engine compartment and protected from access.Space conceptThe larger vehicle interior offers a completely new sense of space – this is achieved by an increased vehicle length, larger wheelbase and increased interior widths. The lowered beltline offers a more generous sense of space especially at the rear. The luggage compartment has large dimensions – it has a lowered load sill and a wider loading area.HeadlightsThe headlights on the Jetta 2011 are designed using clear glass technology. Side marker lamps are integrated into the headlamps on the outside left and right. Daylight driving lights and indicators are still located under the dipped beam and main beam headlights.DoorsThe doors of the Jetta 2011 have a conventional design. A side impact bar is installed in each door.RoofDepending on the equipment, a sliding sunroof is installed and the aerial for GPS (navigation system aerial) and for SAT (satellite tuner aerial) is mounted, at the rear end of the roof.14Rear seat benchThe rear seat bench is split 60 : 40 and can be folded. The release mechanism for folding down the two halves of the rear seat bench can be actuated at the rear, in the luggage compartment.Actuation for releasing the rear seat bench (releasing of the left half of the rear seat bench is illustrated) Luggage compartment lidRear windowThe aerials for radio reception are integrated into the rear window.S468_041Luggage compartment lidThe luggage compartment lid is opened from the outside using a micro button in the rear lid handle. The rear lid lock is equipped with an emergency release mechanism. It consists of a swivel plate that needs to be turned from the inside of the luggage compartment to open the rear lid. The luggage compartment lid has a completely new hinge concept with a new hinge and tension springs at the sides. The automatic full opening of the luggage compartment lid is thus enabled with significantly reduced closing forces.S468_066Rear lightsThe Jetta 2011 has two-piece rear lights.HingeS468_082 Tension spring15Occupant protectionSafety equipmentThe Jetta 2011 is fitted with the following primary safety equipment:q q q q qDriver airbag Front passenger airbag Front side airbags Curtain airbags for front and rear occupants Belt tensioners and belt force limiters for the front seatsqTop TetherDepending on the specific market, the Jetta 2011 is equipped with the Top Tether system. The Top Tether system serves to secure a child seat more firmly by means of an additional upper belt on the child seat that is attached to corresponding retainers on the rear shelf.Cover with Top Tether letteringTop Tether retainerqSensors for front and side crash detection are mounted in the front end, in the front doors and in the vicinity of the C-pillar.S468_03316qCapacitive seat occupancy recognition (market-specific)A new system will be installed in the Jetta 2011 for seat occupancy detection in the USA and in Canada. The system uses sensors based on a capacitive principle of operation.The sensor system consists of a sensor mat with evaluation electronics.Sensor matEvaluation electronicsS468_050qThe outer rear seats are equipped with Isofix attachment pointsS468_06817EnginesEngine/gearbox combinationsPetrol engine 5-speed manual gearbox MQ200-5F 0AFDiesel engine2.0 l / 85 kW petrol engine with 2-valve technology (engine for USA and Canada)2.0 l / 103 kW TDI common rail engine2.5 l / 125 kW petrol engine with 4-valve technology185-speed manual gearbox MQ250-5F 0A46-speed manual gearbox MQ350-6F 02Q6-speed automatic gearbox AQ250-6F 09G6-speed dual clutch gearbox DQ250-6F DSG 02E19The 2.0 l / 85kW petrol engineThe 2.0 l / 85 kW petrol engine has been adapted according to the installation postion for fitting in the Jetta 2011.Technical featuresqq q q qSingle-piece plastic intake manifold, with integrated Volkswagen logo as design cover Ancillary drive for hydraulic power steering Pistons optimised to minimise oil consumption New throttle valve module generation Electrically heated crankcase breatherS468_016Technical dataEngine code Type Displacement Bore Stroke Valves per cylinder Compression ratio Maximum output Maximum torque Engine management Fuel Exhaust gas aftertreatment CBPA 4-cylinder in-line engine 1981 cm3 82.5 mm 92.8 mm 2 10.3 : 1 85 kW at 5200 rpm 170 Nm at 4000 rpm Bosch Motronic ME 17.5.6 Premium unleaded RON 95 according to DIN EN 228 Probe before catalytic converter: linear lambda probe, probe after catalytic converter: transient probe BIN5/ULEV 2* EU4** Torque (Nm)Torque and power diagramEngine speed (rpm) S468_017* USA/Canada ** ArgentinaEmissions standard20Output (kW)The 2.0 l / 103 kW CR TDI engineThe 2.0 l / 103kW CR TDI engine with common rail injection system was used for the first time in the Tiguan.Technical featuresq qq q q qCommon rail injection system with piezo injectors Diesel particulate filter with upstream oxidising catalytic converter Intake manifold with swirl flap adjustment Electric exhaust gas recirculation valve Adjustable turbocharger with travel feedback Low-temperature exhaust gas recirculation cooling*For the USA and Canada, this engine has been further developed to ensure compliance with the strict emissions limit values of emissions legislation BIN5/ULEV2.

Some details have been further developed and adapted for use in the Jetta 2011. The technical features include:q q qAssembly carrier (subframe) made of sheet steel Wishbones, single shell, made of sheet steel Rear rubber-metal bearing with vertical axisWishbone, left (example)Bonded rubber mounting (vertical axis)Coupling rod S468_081Anti-roll barWishboneAssembly carrier (subframe)Gearbox pendulum supportS468_008Front brakesDisc brakes are used for the front axle.26Rear axleThe newly developed twist beam axle is used for the rear axle of the Jetta 2011. The technical features include:qqThe axle body is a welded construction made of steel sections. The cross member improves axle housing stability by preventing uncontrolled lateral movements of the axle housing.qThe steel subframe is bolted onto the body’s longitudinal profiles on the right and left. It increases body stability in this area so that the forces resulting from the cross member’s movement can be more easily absorbed.Cross member Axle bodySubframe connection to the body SubframeMounting bracket (connection to body)S468_009Rear brakesDrum brakes are used in combination with the 2.0 l / 85 kW petrol engine.

A power steering fluid reservoir is integrated into the power steering’s hydraulic system.The steering column is already used in the Golf 2009. The steering system in installed specifically for each engine – the example illustrates a hydraulic power steering used with the 2.5 l / 125 kW engine.Power steering fluid reservoirPower steering pumpSteering columnS468_014Steering boxHydraulic control unit for steering box28Electromechanical power steeringAvailable in combination with the 2.0 l / 103 kW TDI engines. The same steering column is used for the electromechanical power steering as for the hydraulic power steering.Input shaft Index sensor integrated in the torque sensor Steering boxTriple bearingElectric motor with rotor position sensor S468_015The electromechanical power steering is already used in the Golf 2009. It is an electromechanical power steering system with double pinions of the 3rd generation from ZF. The essential features include:qq qIntegration of the steering angle sensor in the steering system – the steering angle sensor on the steering column control unit is thus no longer required Software expansion in the control unit, e.g. for steering angle sensor Triple bearing on the assembly carrierCalculating the steering angle With the 3rd generation electromechanical power steering, the vehicle’s steering angle is calculated using the sensor signals recorded in the steering system from the rotor position sensor on the electric motor and from the index sensor. This steering angle is used for the internal steering functions and also made available to other control units.29Running gearBrakesDifferent brake systems are used for the Mexico market and the USA and Canada market. The brakes are installed in the vehicle in the same way – only the ABS/ESP units differ. For the engines described in the self-study program, a 10" brake servo is used.S468_043ABS/ESP unitBrake servoABS systemThe Jetta 2011 will be available in the Mexican market with ABS. The ABS unit MK70 is made by Continental Teves. The ABS unit MK70 is characterised by the following features:qHydraulic unitqAnti-lock brake system (ABS) with electronic brake pressure distribution (EBD) Traction control system (TCS)S468_010Control unit30ESP systemThe Jetta 2011 will be equipped with ESP for the USA and Canada. The ESP unit MK60 EC is already used in the Golf 2009. It is also made by Continental Teves. The ESP unit MK60 EC is characterised by the following features compared to the MK70:q q qHydraulic unitElectronic stabilisation programme (ESP) Electronic differential lock (EDL) Brake assist systemS468_011The electronic stabilisation programme is switched on permanently.Control unitThe new feature of this ESP unit compared to the previous model, MK60, is that the previous sensor cluster with the yaw rate sensor and the longitudinal and transverse acceleration sensors are no longer required. These sensors are now integrated in the printed circuit board in the control unit for ABS/ESP.PCB in control unit for ABS/ESPLongitudinal and transverse acceleration sensorS468_012Yaw rate sensor31Running gearTyre pressure monitor (TPM)The tyre pressure monitor, TPM, is a software module in the control unit for ABS/ESP that evaluates the wheel speed sensor data of the ABS/ESP unit to monitor the tyre inflation pressure. A new tyre pressure monitor is used in the Jetta 2011 in specific markets, with an extended scope of functions compared to the previous version. It is used as the standard in the USA.More detailed information on the tyre pressure monitor, TPM, is available in self-study programme No. 347 “Tyre Pressure Monitor Systems”.FunctionA decreasing tyre inflation pressure reduces the rolling radius of the respective wheel, which rotates faster at the same vehicle speed. The wheel speed sensors calculate the difference in speed, which is then evaluated in the control unit for ABS/ESP. A warning lamp in the dash panel insert and an acoustic signal inform the driver, requesting that the tyre inflation pressure be checked. A resonance frequency is measured in addition to the speed. This results in a more precise assessment of the loss in pressure. The tyre pressure monitor is capable of simultaneously detecting a gradual loss in air pressure for several wheels simultaneously. Since the tyre characteristics of each individual tyre deviate, determination of the reference data requires the system to be calibrated with the currently fitted tyres and the pressure values stored in the system. After a changing the tyre inflation pressure of one or more wheels, the system will also have to be recalibrated. That also applies to a wheel change, after which the inflation pressure needs to be set to the required value and then the system recalibrated.Control unit in dash panel insert Control unit for ABS with integrated software for tyre pressure monitor (TPM) Button for tyre pressure monitorS468_027Snow chain recognition – the system is not active if snow chains are detected.32CalibrationTo calibrate, press the button for the tyre pressure monitor with the ignition switched on until a confirmation tone can be heard. That confirms that the tyre inflation pressure values determined during calibration have been saved to the tyre pressure monitoring system as the required tyre inflation values. The button for the tyre pressure monitor is in the glove box, at the top left.S468_025Monitor warningIf the value saved for the required tyre inflation pressure during calibration at any one wheel falls short by a certain value, the system warns the driver by a gong and the yellow warning lamp for the tyre pressure monitor in the dash panel insert. The lamp stays on until the system has been recalibrated. As long as this has not been done, the gong will sound at each start.S468_026If a service is performed, the service staff must inform the driver that he or she is responsible for ensuring that the correct tyre inflation pressure is set. The tyre pressure monitor is an information system that emits a signal in the event of pressure loss in a tyre. It does not relieve the driver of the responsibility to check the tyre inflation pressures on his or her own at regular intervals.33Electrical systemVehicle electrical systemInstallation locations in the vehicle electrical systemThe installation locations of important electrical components in the Jetta 2011 have changed compared to the previous model. The adjacent illustration shows the installation locations.Onboard supply control unit on the rear side of a plastic housing Plastic housingElectronics box on the left of the battery in the engine compartmentRelay carrier on the front side of the plastic housing – topFuse holder on the front side of the plastic housing – bottom34Vehicle electrical system architectureThe Jetta 2011 is equipped with a modified electrical system that essentially is identical to the T5 2010 or of the Polo 2010. However, components are also used from the vehicle electrical system of the Golf 2010. The relay carrier has a special converter box. It amplifies the control signals of the ignition lock, the electric steering column lock and onboard supply control unit, links them to other signals and actuates mechanical relays. The ignition starter lock is also implemented via the converter box in combination with the onboard supply control unit.Converter boxS468_07235Electrical systemOnboard supply control unitThe Jetta 2011 has an onboard supply control unit that is already used in the T5 2010 or the Polo 2010. It now also includes the functions of the central convenience system control unit J393. Furthermore, the diagnostic interface for data bus J533 is not a separate, independent control unit, but integrated into the onboard supply control unit. The new onboard supply control unit is only connected via two 2 connectors. The onboard supply control unit is installed under the dash panel on the left, on the back of a housing with fuses and relays fitted on its front.Onboard supply control unit J519 with 2 socketsS468_035Housing for relays, fuses and onboard supply control unitThe aerial for radio remote control is integrated into the onboard supply control unit.Functions of the onboard supply control unit Load management Actuation of fuel supply line for electric fuel pump Door contact actuation Exterior mirror heating actuation Seat heating release The information of the externally dimmed interior light is placed on the CAN data bus Reversing light Fog light Shift lock Interlock Windscreen wipers stage I/II actuation Windscreen wiper interval control Convenience rear wiper actuation (belongs to the scope of functions – but is not used in the Jetta 2011) Door LIN data bus (door control units/multifunction steering wheel) Roof LIN data bus (sliding/tilting roof) Cruise control system Brake light, indicator and hazard warning light actuationStarter repeat lock Horn actuation Release and actuation of sliding/tilting roof Side light and parking light actuationRear window heating actuation Rear lid release actuation Powertrain, convenience and diagnostics CAN data bus Data bus diagnostic interface (gateway) K-line Radio remote control (315 MHz) Function block for “Keyless Access” locking and start system (Kessy) Central lockingAnti-theft alarm system36The “Keyless Access” locking and start systemThe Jetta 2011 can be equipped with the “Keyless Access” locking and start system for specific markets. The system can be used to unlock and lock the vehicle without active use of the vehicle key and to start and shut down the engine using the button.System architectureThe “Keyless Access” locking and start system is an optional equipment variant of the Jetta 2011. In the overview, the system architecture is compared with and without “Keyless Access” system.System architecture without “Keyless Access” Key with radio remote controlSystem architecture with “Keyless Access” Key with “Keyless Access” and radio remote controlRadio 315 MHzRadio 315 MHzRadio 125 kHz“Keyless Access” transmitter aerials (doors, interior, luggage compartment)Ignition lock“Keyless Access” control unit“Keyless Access” door handles (front) with proximity sensorElectric steering column locking mechanismButton for starter systemConverter boxConverter boxOnboard supply control unitOnboard supply control unitVehicle electrical system (remaining vehicle)Vehicle electrical system (remaining vehicle)Green = identical interfaces and control unitsS468_076Mechanical interfacesA component worth mentioning in the “Keyless Access” locking and start system is the electric steering column locking mechanism (ESL), which replaces the mechanical steering column lock.37Electrical systemElectrical interfacesAs in a basic vehicle without “Keyless Access” locking and start system, the onboard supply control unit consists of the electronic module with high-frequency receiver (radio receiver) for the central locking system. The onboard supply control unit is integrated in the CAN data bus via which various configurations, information exchange etc. are implemented in the system. Additional components are the electrical steering column locking mechanism (ESL) with separate control unit, the entry and start authorisation control unit J518 (“Keyless Access”) including aerials and door handles and the vehicle key (ID sender).Driver interfacesThe “Keyless Access” locking and start system ensures the identification of the key inside and around the vehicle. The aerials fitted in the front door handles and in the vehicle interior are for connecting the vehicle key to the “Keyless Access” system. After the successful identification, the following functions are enabled:qqqKeyless entry – the handle of the driver or front passenger door is used to unlock the vehicle – clasp the handle [A]. The ID sender must be within the outside range on the corresponding vehicle side or in the vehicle’s rear end. Keyless go – start the engine and go – for this, there must be a valid ID sender in the vehicle. To start the vehicle, the button for the starter system and the clutch (for versions with manual gearbox) or the brake (for versions with automatic gearbox) need to be actuated. Keyless exit – to lock the vehicle on leaving it – the driver door must be closed – actuate the outer button in the handle of the driver or front passenger door [B]. If the vehicle is locked via the front passenger door, it must be closed. The ID sender must be within the outside range on the corresponding vehicle side or behind the vehicle.qOutside range (detection range) – keyless access of the driver to the vehicle via the “Keyless Access” door handle (driver/front passenger side). To detect the vehicle unlocking request, capacitive sensors are fitted in the door handle.
