Body Audi Space Frame ASF of the Audi TT Coupé ´07 The development targets for the bodyshell of the Audi TT Coupé ‘07 With a weight advantage of 48 % over a comparable all-steel bodyshell, not to mention the optimised weight distribution, the new composite aluminium-steel spaceframe body of the TT Coupé marks yet another milestone in the development of modern Audi bodyshells.
Technological concept Sheet-steel parts are used for the first time in the ASF of the Audi TT Coupé ‘07, in addition to aluminium castings, aluminium extruded sections and aluminium sheet-metal parts. Collectively they form the body structure. Vehicle weight distribution is optimised by using sheet-steel parts at the rear end of the body.
Occupant protection Occupant protection system in the Audi TT Coupé ‘07 The Audi TT Coupé ‘07 is a high-end sports car. However, the occupant protection system matches the vehicle's driving dynamics in every respect. Creating a sports car with a high occupant protection potential is always a big challenge. This challenge was met by the TT Coupé development team.

Occupant protection Airbag control unit J234 Airbag control unit J234 and integrated electronics have the task of detecting a collision. In the Audi TT Coupé ‘07 the airbag control unit is attached to the vehicle body in the area of the handbrake lever. The airbag control unit is integrated in the CAN powertrain data bus so that it can exchange information with other control units.
Belt-on warning The Audi TT Coupé ‘07 has a belt-on warning function for the driver. The airbag control unit evaluates the information from the driver side belt switch E24 after ignition "on". If the driver is not wearing a seat belt, a visual warning is given by the seat belt warning system warning lamp K19 integrated in the dash panel insert.If the system determines that the vehicle is moving, an audio warning is given in addition to the visual warning.
Occupant protection Airbag The Audi TT Coupé ‘07 has two-stage front airbags on the driver and front passenger sides. The airbag control unit selects the time interval between the two ignition stages (approx. 5 ms to 30 ms) according to severity and type of crash. The loads acting on the driver or front passenger during an accident can be reduced through time-staggered ignition of the propellant charges. Both propellant charges are always ignited.
Front passenger airbag Airbag igniter 1, front passenger side N131 Airbag igniter 2, front passenger side N132 An airbag module with a two-stage hybrid gas generator is used in the Audi TT Coupé ‘07 on the front passenger side.This module is already in use in the Audi Q7. However, it has been adapted for the TT Coupé. Two pyrotechnic propellant charges integrated in a pressurised gas bottle are activated separately by the airbag control unit.
Occupant protection Side airbags Side airbag igniter, driver side N199 Side airbag igniter, front passenger side N200 Airbag modules which cover both the body and head areas - so-called head-thorax airbags - are used as side airbags. Tubular gas generators filled with solid propellant inflate the airbags with gas in the event of a crash. 380_004 The airbag control unit J234 energises the corresponding side airbag igniter.
Driver seat belt tensioner igniter -1- N153 Front passenger seat belt tensioner igniter -1- N154 The Audi TT Coupé ‘07 is equipped with redesigned belt tensioners for the driver and front passenger. These belt tensioners are so-called "band tensioners". The TT Coupé for the North American market is also equipped with these belt tensioners. Seat belt Inertia-reel seatbelt If the rear seats in the TT Coupé are equipped with Isofix fixing eyelets, belt tensioners are also installed for these seats.
Occupant protection The belt tensioner igniter is located inside the metal band loop. When the igniter is activated by the airbag control unit, the resultant pressure causes the loop of the metal band to expand.The movement of the metal band exerts a pull on the seat belt retractor shaft, which thereupon begins to rotate, tensioning the seat belt.
Battery isolation igniter N253 The battery isolation igniter has the task of disconnecting the starter and alternator leads from the vehicle battery in the event of a crash. Use is made of a pyrotechnic component which is activated by the airbag control unit J234 whenever the airbag is deployed. During a rear collision, only the belt tensioner and the battery isolation igniter are activated.
Occupant protection Additional functions and components of the occupant protection system for the North American market The additional functions and components of the occupant protection system for the North American market are described on the following pages. The occupant protection system is equipped with additional functions and components, e.g. second crash sensor for front airbag, so that the Audi TT Coupé ‘07 meets the statutory and marketspecific requirements for the US market.
Knee airbag igniter, driver side N295 Knee airbag igniter, front passenger side N296 The Audi TT Coupé ‘07 for the North American market is equipped with knee airbags for the driver and front passenger sides. Ignited knee airbags allow the occupants to participate earlier in the vehicle deceleration process. The airbag system of driver and front passenger front airbags in combination with knee airbags reduces the injury risk for the occupants.
Occupant protection Belt force limiter, driver side G551 Belt force limiter, front passenger side G552 The front inertia-reel seatbelts have a two-stage belt force limiter. In the event of a collision, the belt tensioners (band tensioners) are ignited first. The inertia-reel seatbelt blocks the seat belt retractor shaft and prevents the seat belt from unreeling, which would occur due to the forwards movement of the occupants. The seat belt retractor shaft is designed as a torsion shaft.
The belt tensioner retracts the seat belt to the extent possible, and the inertia-reel seatbelt locks the seat belt retractor shaft. The seat belt can no longer be pulled out. If the occupant's body now accelerates forwards due to centrifugal force, the belt force limiter allows the seat belt to unreel as of a certain force.Both torsion shafts are rotated.

Fuel supply The fuel system is basically adopted from the A3 `04. The fuel tanks differ from one another in terms of their shape, which is dependent on the vehicle's drive concept. They are made of HPPE (high-pressure polyethylene). To safeguard the fuel tank against destruction in the event of an accident, it is mounted in front of the rear axle. Here it is fixed to the underbody by means of ratchet straps. It is not necessary to disassemble the rear axle to remove the fuel tank.
Engine Pressure regulation The fuel filter is bolted to the exterior of the fuel tank. The pressure regulator is integrated in the fuel filter. In case of excess pressure, the governed fuel is returned to the tank. The pressure regulator in the FSI engine cuts off fuel delivery at 6.4 bar (relative). In the case of the MPI engine, fuel cut-off is at 4 bar (relative).

Engine Soundpipe A soundpipe is used on the 3.2l V6 engine to give the engine a sportier sound. The intake noise is transmitted to the vehicle body via a connecting line from the intake manifold to the plenum chamber and via a resonator. The soundpipe has been developed to accentuate the dynamism and sportiness of the 3.2l engine The soundpipe produces a sporty sound in the vehicle interior without impairing comfort.
Function A soundpipe is connected between the air mass meter and the throttle valve unit in the air intake tract. The soundpipe made up of three parts: the primary pipe, which is connected to the air intake tract, the sound generator and the secondary pipe, which is connected to the vehicle interior via the engine bulkhead.
Suspension system Suspension system Overview The Audi TT Coupé ‘07 is available with three different suspension systems. The dynamic suspension system represents the basic specification. The semi-active "Audi magnetic ride" suspension is optional. The driver can select between comfort and sport suspension settings at the touch of a button. quattro GmbH is also offering an S-Line suspension system, which is sportier than the dynamic suspension system.
Rear axle The rear axle of the Audi TT Coupé ‘07 is basically identical in design and function to the rear axle on the Audi A3. The wheel carriers, damper bearings and wheel bearings are modifications on the components on the Audi A3.Track width has been increased by 15 mm on each side compared to the Audi A3. The suspension and damping components (springs, dampers and anti-roll bars) were adapted to the specific requirements of the TT Coupé. Additional stone chip protection is provided for certain markets.

Air conditioning Overview The air conditioning system of the Audi TT Coupé ‘07 is an improved version of the system used in the Audi A3 ’04. The automatic air conditioning system is configured as a single-zone air conditioning system. The TT Coupé has only one climate zone with no temperature differential between the driver and front passenger sides. The TT Roadster is available with a heating-only system, in addition to the automatic air conditioning system.
Climatronic control unit J255 The setpoint for the temperature flap is set using the "Temperature" rotary knob. The rotary knob is infinitely variable and activates the "Maximum cool" function in the lowest setting and the "Maximum heat" function in the highest setting. Automatic mode of the air conditioning system can be deactivated with the "Air flow" or "Air distribution" rotary knob or by pressing the DEFROST or AC key.
Air conditioning Components of the air conditioning system in the Audi TT Coupé ‘07 Air conditioner compressor Single acting wobble plate compressor with 6 cylinders and variable delivery rate, without magnetic coupling, externally controlled. The air conditioner compressor is not a carry-over part from the Audi A3. The compressor stroke volume is regulated via the air conditioning system compressor regulating valve N280 by means of the PWM signal, depending on cooling power requirements.
Outlet temperature sensor For the driver side, one outlet temperature sensor is installed in the air duct of the chest vent and in the footwell duct. For the front passenger side, only the outlet temperature sensor is installed in the footwell duct. The Climatronic control unit J255 evaluates the outlet temperature sensor in dependence on the air distribution and determines from this the actual outlet temperature.
