2.1 Calculating ratio “i”

Example:
Drive gear ZG1 = 38 ZA1 = 22
Driven gear ZG2 = 35 ZA2 = 69
i = Z2 : Z1 (Z1 = number of teeth on drive gear, Z2 = number of teeth on driven gear)
iG = gear ratio = ZG2 : ZG1 = 35 : 38 = 0.92
iA = axle ratio = ZA2 : ZA1 = 69 : 22 = 3.136
iov = overall ratio = iG x iA = 0.92 x 3.136 = 2.89

5 Notes on the direct shift gearbox 02E

5.1 General notes

Gearbox
The direct shift gearbox 02E is also referred to as a dual-clutch gearbox. The engine torque is transferred to the gearbox via the dual-mass flywheel. The layout of the gearbox is basically similar to that of a 6-speed manual gearbox. The two multi-plate "wet" clutches are regulated hydraulically and actuated alternately so that the gearbox is operated like an automatic gearbox, i.e. the gears are engaged automatically (or manually via the tiptronic function). There is no clutch pedal. For further information please refer to ⇒ Self-study programme No. 308 ; Direct shift gearbox 02E .
Selector mechanism
The selector lever position is no longer transmitted mechanically via the selector lever cable and multi-function switch (driving range sensor) as on the automatic gearbox. The selector lever positions and gear changes are transmitted to the gearbox control unit by a separate selector mechanism control unit via CAN bus. This means that gear shifts are effected without a cable. Excep‐ tion: In selector lever position “P” the selector lever cable is used to mechanically engage the parking lock.
Gear oil
The gear oil level in gearbox and final drive (front) is checked and topped up together ⇒ page 74 .

5.2 Safety functions of gearbox control unit

In the event of a failure of one or more components/sensors, the gearbox control unit will activate appropriate backup functions. This ensures that the gearbox will not be damaged, however, the function and quality of the gear shifts will be impaired.
Faults detected by the gearbox are classified in four different cat‐ egories.
♦ 1) The fault is stored and a backup programme enables the
vehicle to drive on (in some cases with restrictions). The driver will not be made aware of the problem, as it is not critical to driving safety or to the gearbox itself. The gear selection indi‐ cator in the instrument cluster will continue to show the selec‐ tor lever position currently engaged in the normal way. If at all, the driver will only notice the fault if he experiences driveability problems, and will then automatically contact an Audi Service Partner to identify the cause.
♦ 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 available. Example: position “D” is not available when selector lever is in position “R” and vehicle is still rolling backwards. In this case, selector lever position “D” will start to flash on the gear selec‐ tion indicator in the instrument cluster. The gearbox control unit prevents the 1st gear from being engaged in order to avoid damage to the gearbox. 1st gear will be engaged once the vehicle has come to a standstill.
♦ 3) The complete gear selection indicator in the instrument
cluster is lit up and flashing. The current selector lever position is indicated in the instrument cluster (e.g. “D” is highlighted). This is an indication that the gearbox has been overloaded or the maximum temperature in the gearbox has been exceeded (overheating), e.g. towing a load that was too heavy.
♦ 4) If the complete gear selection indicator in the instrument
cluster is lit up and flashing, this means that a serious fault in the gearbox has been identified. The display in the instrument cluster no longer shows the current selector lever position. The defect is critical with regard to driving safety or the gearbox itself. It may no longer be possible to use all gears. The driver is made aware by the flashing gear selection indicator that he should immediately contact an Audi Service Partner.

30 – Clutch

1 Servicing multiple clutch

♦ The clutch in the direct shift gearbox 02E consists of two sets
of plates, and is therefore referred to as a “multiple clutch”. The larger set of plates (located on the outside) 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:
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 gearchanges and reduce the service life of the unit.

1.1 Multiple clutch - exploded view of components (replacement parts)

1 - Multiple clutch with circlip
Caution
♦The drive plate (top sec‐ tion of multiple clutch) of a new clutch is not se‐ cured with the circlip, it is only a “close fit” in the clutch.
♦The drive plate must re‐ main engaged between the splines of the outer plate carrier.
♦If the drive plate comes loose, the clutch plates can slip out of position in‐ side the multiple clutch unit. If this happens, it may not be possible to adjust the multiple clutch correctly during installa‐ tion.

it is only a “close fit” in the clutch.
♦ While carrying out the following steps you must therefore
hold the drive plate by pressing it into the outer plate car‐ rier with both thumbs.
♦ The drive plate must remain engaged between the splines
of the outer plate carrier.
♦ If the drive plate comes loose, the clutch plates can slip
out of position inside the multiple clutch unit. If this hap‐ pens, it may not be possible to adjust the multiple clutch correctly during installation.
– Take the circlip out of the packaging.
– Take the clutch for direct shift gearbox out of the packaging,
at the same time pressing the drive plate into the outer plate carrier with both thumbs.
– Secure drive plate in outer plate carrier with “old” circlip -A-
from removed clutch.
Do NOT use the new circlip supplied when carrying out this installation.
The circlip must be installed so that the lug on the drive plate
-arrow- and the colour-marked splines on the outer plate car‐ rier are located between the two ends of the circlip.
The circlip must be fully engaged all round.
– Check that the 4 oil seals on the hub on the underside of the
multiple clutch are correctly seated; engage in position if nec‐ essary.
The joints of the seals should be offset and not aligned one above the other.

2.1 Checking selector mechanism

♦ It should not be possible to operate the starter while the se‐
lector lever is in position “S”, “D” or “R” or in the tiptronic position.
♦ When travelling at speeds above 5 km/h and shifting into se‐
lector lever position “N”, the solenoid for the selector lever lock must not engage and block the selector lever. The selector lever can be shifted into a driving gear.
♦ When travelling at speeds below 5 km/h (almost stationary)
and shifting into selector lever position “N”, the solenoid for the selector lever lock should only engage after about 1 second. Selector lever cannot be shifted out of “N” position until brake pedal is depressed.
Selector lever in position “P”, button on selector lever pressed in and ignition switched on:
Brake pedal not depressed:
When button is pressed in, selector lever is locked and cannot be shifted out of “P” position. Solenoid for selector lever lock blocks selector lever.
Brake pedal depressed:
Solenoid for selector lever lock releases selector lever. It is pos‐ sible to shift into a driving gear. Shift selector lever slowly from “P” position through “R, N, D and S” and check whether the dis‐ play in the dash panel insert shows the correct selector lever position in each case.

Caution
♦ The engine must not be started if significant oil loss has
occurred (e.g. during repairs) and there is little or no oil left in the gearbox.
♦ In this case, you must carry out a pre-filling of gear oil for
the direct shift gearbox.
♦ Only the gear oil for the direct shift gearbox (available as
a replacement part) may be used for the direct shift gear‐ box 02E. Other types of oil will cause malfunctions and/or failure of the gearbox; for Part No. refer to ⇒ Parts cata‐ logue .

Gear oil in overflow pipe -arrow 2- will drain off first.
Note
Even when the gear oil level is too low a small amount of oil will first drain out of the overflow pipe, as it fills up during operation.
– Check that the overflow pipe is secured to the gearbox with a
torque of 5 Nm and tighten if necessary.
Note
If the overflow pipe is not correctly secured, the oil level cannot be correctly read.
– Allow excess gear oil to drain off.
The gear oil level is correct when a small amount of gear oil still drains out when the oil temperature is between 35 °C and 45 °C (oil level rises due to warming of oil).
In this case, the gear oil does not need to be topped-up; oil level is OK.
Note
Every 30 seconds a small surge of oil will come out of the oil level pipe regardless of the oil level (cause: intermittent cooling oil supply to the clutch). The surge is not to be considered a criteria for the correct oil level and should therefore be disre‐ garded.
Gear oil that has drained off must not be refilled or reused. Dispose of the gear oil properly.
If no gear oil drains out when the oil temperature is between 35 ° C and 45 °C, top up gear oil ⇒ page 79 .
– Always renew the seal -arrow- for the gear oil inspection plug.
