Gearbox
♦ Do not run the engine or tow the vehicle with the oil pan re‐
moved or when there is no gear oil in the gearbox.
♦ Thoroughly clean all joints and connections and the surround‐
ing areas before disconnecting.
♦ When installing gearbox, ensure that dowel sleeves are fitted
correctly.
O-rings, seals, oil seals and gaskets
♦ Always renew O-rings, seals, 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.
♦ Thoroughly clean housing joint surfaces before assembling.
♦ Always replace paper gaskets. Completely remove old gasket
and clean sealing surfaces thoroughly.
♦ Lightly lubricate the outer circumference and sealing lip of oil
seals with gear oil before installing.
♦ Lightly lubricate O-rings with gear oil or vaseline before instal‐
lation to prevent them from getting crushed during assembly.
♦ 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 seals faces toward the side with fluid
filling.
♦ When installing a new oil seal, position the seal in the housing
so that the sealing lip does not contact the shaft in the same
place as the old seal (make use of installation depth toleran‐
ces).
♦ Observe rules for cleanliness ⇒ page 6 .
Locking elements
♦ Do not over-stretch circlips.
♦ Renew circlips which have been damaged or over-tensioned.
♦ Circlips must be properly seated in the base of the groove.
Nuts, bolts
♦ Loosen bolts in reverse sequence to the specified tightening
sequence.
♦ Bolts and nuts 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 apply locking fluid -
AMV 185 101 A1- to bolt threads before installing.
♦ The tightening torques stated apply to non-oiled nuts and
bolts.

WARNING
System is pressurised.
The “7-speed dual clutch gearbox 0CJ, 0CK, 0CL” is equipped
with an electric ATF pump and hydraulic accumulator.
The electric ATF pump may start up at any time.
Because of the hydraulic accumulator, the ATF system is pres‐
surised even when the ignition is off.
♦ The electric ATF pump must always be deactivated and
the hydraulic accumulator must be discharged before
opening the gearbox.
♦ If the current state of the system is unclear (e.g. if the
gearbox control unit is defective or if the gearbox is from
an unknown source), only loosen the bolts on the mecha‐
tronic unit very slightly so that the oil pressure in the
accumulator can dissipate slowly.
♦ Unplug electrical connector on automatic gearbox control
unit - J217- before removing oil pan.
♦ Put on safety goggles.
Deactivating ATF pump and discharging hydraulic accumulator
– Connect Vehicle diagnostic tester and start Diagnosis mode.
♦Select own test
♦02 - Gearbox electronics, Functions
♦ Select 02 - ATF pressure relief / Disable ATF pump
or 02 - ATF level ⇒ Drain off ATF
4.4 Contact corrosion
Contact corrosion can occur if unsuitable fasteners are used (e.g.
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 .
Please note:
♦ We recommend using only genuine replacement parts; these
have been tested and are compatible with aluminium.
♦ We recommend the use of accessories approved by Audi.
♦ Damage caused by contact corrosion is not covered by war‐
ranty.
4.5 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 selector lever posi‐
tion display in the instrument cluster will continue to show the
selector 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 selector lever position display in the
instrument 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 the selector lever
is in position “R” and the vehicle is still rolling backwards. In
this case, selector lever position “D” will start to flash on the
selector lever position display in the instrument cluster. The
gearbox control unit prevents 1st gear from being engaged in
order to avoid damage to the gearbox. 1st gear will be engag‐
ed once the vehicle has come to a standstill.
♦ 3) The complete selector lever position display in the instru‐
ment cluster is lit up and flashing. The current selector lever
position is indicated in the instrument cluster (e.g. “D” is high‐
lighted). This is an indication that the gearbox has been over‐
loaded or the maximum temperature in the gearbox has been
exceeded (overheating), e.g. towing a load that was too heavy.
♦ 4) If the complete selector lever position display in the instru‐
ment cluster is lit up and flashing, this means that a serious
fault in the gearbox has been identified. The display in the in‐
strument 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 indi‐
cator that he should immediately contact an Audi Service
Partner.
