5 Notes on the direct shift gearbox 02E

5.1 General notes

Gearbox
The direct shift gearbox 02E is a dual-clutch gearbox, also refer‐ red to as “S tronic”. It has the same basic construction as a 6­speed manual gearbox. The engine torque is transferred to the gearbox via the dual-mass flywheel. The two multi-plate "wet" clutches are controlled hydraulically and actuated alternately so that the gearbox is operated like an automatic gearbox, in other words the gears are engaged automatically (but can also be se‐ lected manually via the tiptronic function). There is no clutch pedal. For further information please refer to ⇒ Self-study pro‐ gramme No. 308 ; Direct shift gearbox 02E .
Selector mechanism
In selector lever position “P” the selector lever cable is used to engage the parking lock mechanically. All other gearshift com‐ mands and selector lever positions are transmitted via the CAN data bus from the selector lever -E313- (selector mechanism) to the mechatronic unit for dual clutch gearbox -J743- .
Gear oil (gearbox and final drive)
The direct shift gearbox and front final drive have a common filling of gear oil ⇒ page 94 .
Note
Use only the correct type of gear oil for the direct shift gearbox 02E (available as a replacement part). Other types of oil will cause malfunctions and/or failure of the gearbox; for Part No. refer to ⇒ Electronic parts catalogue .
The bevel box has a separate oil filling ⇒ page 149 .
Note
Use only the correct type of gear oil (available as a replacement part) for the bevel box. Other types of oil will cause malfunctions and/or failure of the bevel box; for Part No. refer to ⇒ Electronic parts catalogue .
Regulations for the disposal of oil
Drained oil must be disposed of properly.
♦ Improper disposal of used oil endangers the environment.
♦ It must not be mixed with solvents, brake fluid, coolant or sim‐
ilar.
♦ Please observe the information shown on the packaging of the
oil.
Variation of gear-change points for gradients
Additional gear-change maps automatically select the gear­change points for gradients according to accelerator pedal posi‐ tion and road speed.
The gear-change map for extreme uphill gradients is matched to the engine power.

Direct shift gearbox 02E, four-wheel drive - Edition 08.2008
The gear-change map for extreme downhill gradients is matched to the engine braking effect.
By selecting a gear directly via the tiptronic mode, it is possible to make use of the engine braking effect available in a partic‐ ular gear, for instance when driving downhill with a trailer.

5.2 Safety functions of gearbox control unit

In the event of a failure of one or more components or sensors, the control unit J743 will activate appropriate backup functions. This enables the gearbox to continue operating without damage, but will impair the operation and smoothness of the gearshifts.
Faults detected by the gearbox are classified in four different cat‐ egories.
1 - The fault is stored in the memory and one of the backup
programs is activated. The gear selection indicator in the instrument cluster will continue to show the currently en‐ gaged selector lever position in the normal way. The driver can continue to drive the vehicle (with certain restrictions), and the condition is not critical to the safety of the vehicle or to the gearbox itself. If at all, the driver will only notice the fault if he experiences driveability problems, and will then automatically contact an Audi Service Partner.
2 - Certain positions on the gear selection indicator in the in‐
strument cluster start to flash. This is to inform the driver that this particular selector lever position is currently not availa‐ ble. Example: position "D" will start flashing if the selector lever is moved from position "R" to position "D" while the vehicle is still rolling backwards. To avoid damage to the gearbox, the mechatronic unit for dual clutch gearbox -J743­prevents 1st gear from being engaged while the vehicle is moving backwards. 1st gear will only be engaged when the vehicle comes to a standstill.
3 - The complete gear selection indicator lights up and flashes;
the currently engaged selector lever position is highlighted. This shows the driver that a temporary critical fault in the gearbox has been detected. Example: the gearbox has been overloaded or overheated, for instance by towing an excessively heavy load. The driver can continue to drive the vehicle when the gearbox has cooled off, but will need to avoid placing a heavy load on the transmission.
4 - The gear selection indicator flashes; the currently engaged
selector lever position is no longer indicated. This shows the driver that a critical and permanent fault in the gearbox has been detected. It may no longer be possible to use all gears, so this condition is critical to the safety of the vehicle and to the gearbox itself. This display is intended to warn the driver that he should contact an Audi Service Partner.

Audi TT 2007 ➤ Direct shift gearbox 02E, four-wheel drive - Edition 08.2008
O-rings, oil seals and gaskets
♦ Renew O-rings, oil seals and gaskets.
♦ After removing gaskets and seals, always inspect the contact
surface on the housing or shaft for burrs resulting from removal or for other signs of damage.
♦ Renew gaskets: completely remove the old gasket and clean
the sealing surfaces thoroughly.
♦ Lightly lubricate O-rings with gear oil before installation to pre‐
vent them being trapped and damaged during assembly.
♦ Lightly oil the outer circumference of oil seals and pack the
space between the sealing lips -arrow- about half-full with sealing grease; for sealing grease refer to ⇒ Electronic parts catalogue .
♦ Do not use any other lubricants where gear oil is specified.
Otherwise, there is a risk of problems occurring in the gearbox hydraulics.
♦ The open side of the oil seal should face the side containing
the fluid.
♦ Observe rules for cleanliness ⇒ page 14 .
♦ After installation, check gear oil level and top up as required
⇒ page 94 and ⇒ page 149 .
Locking elements
♦ Do not overstretch circlips; renew if necessary.
♦ Circlips must be properly seated in the base of the groove.
Nuts, bolts
♦ Slacken bolts in reverse sequence to the specified tightening
sequence.
♦ Nuts and bolts which secure covers and housings should be
loosened and tightened in diagonal sequence and in stages if no tightening sequence is specified.
♦ Renew self-locking nuts.
♦ Use a wire brush to clean the threads of bolts which are se‐
cured with locking fluid. Then install bolts with locking fluid; for locking fluid refer to ⇒ Electronic parts catalogue .
♦ The tightening torques stated apply to non-oiled nuts and
bolts.
♦ Where instructions specify a torque setting plus an additional
angle, these bolts must be tightened to the specified torque and then turned through the specified angle, e.g. 40 Nm + 90° (90° = a quarter turn).

7.1 Contact corrosion!

Contact corrosion can occur if non-approved fasteners are used on the vehicle (bolts, nuts, washers etc.).
For this reason, only fasteners with a special surface coating are fitted.
Rubber or plastic parts and adhesives also consist of non-con‐ ductive materials.
If you are not sure whether used parts can be re-installed, always fit new parts ⇒ Electronic parts catalogue .

30 – Clutch

1 Exploded view - servicing multiple clutch

♦ The clutch in the direct shift gearbox 02E consists of two sets
of plates, or clutch packs, and is therefore referred to as a “multiple clutch”. The larger clutch pack (located on the out‐ side) is designated “K 1” (clutch 1), and controls the torque flow for reverse gear and gears “1”, “3” and “5”. The smaller set of plates (on the inside) is designated “K 2” (clutch 2), and controls the torque flow for gears “2”, “4” and “6”.
♦ Any work performed on the multiple clutch requires extra care
because all the parts are balanced and matched together in production. If the components are rotated out of their original positions when repairing, this will cause imbalance and impair the smoothness of the gear-changes and reduce the service life of the unit.

– Preload dial gauge to 2 mm and set to “0”.
– Lift up multiple clutch as far as it will go.
– Take reading and note down measured value.
The thickness of the new circlip is calculated according to the fol‐ lowing formula:
Circlip = 2nd measured value – 1st measured value + 1.85 (= constant value)
The thickness of the new circlips is graduated in steps of 0.1 mm. When selecting the required circlip, round up or down to the near‐ est 10th of a millimetre as required. In other words, values up to
0.049 are rounded down and values of 0.050 and above are roun‐ ded up.
Example:
♦ Calculated value for new circlip is 2.27 mm: round up to the
nearest 10th and select circlip with a thickness of 2.3 mm.
♦ Calculated value for new circlip is 2.24 mm: round down to the
nearest 10th and select circlip with a thickness of 2.2 mm.
Note
If the calculated thickness of the new circlip is exactly 2.0 mm, the circlip fitted previously for taking the measurement does not have to be removed.
