6 Repair instructions
6.1 Contact corrosion!
General information:
Contact corrosion can occur if non-approved fasteners such as
bolts, nuts, washers etc. are used on the vehicle.
For this reason, only fasteners with a special surface coating are
fitted. These parts can be identified by their greenish colour.
Rubber, plastic and adhesives also consist of non-conductive
materials.
If you are not sure whether used parts can be re-installed, always
fit new parts.
The following applies in particular to gearboxes:
♦ The housing of the multitronic gearbox 01J is made of a mag‐
nesium alloy.
♦ Bolts and other components which have direct contact with the
gearbox have a surface coating which is compatible with the
magnesium gearbox housing.
♦ On gearboxes built of magnesium, the bolts must always be
renewed on the following bolted connections: gearbox cover
to gearbox housing, final drive cover to gearbox housing and
engine to gearbox.
♦ If the incorrect components are used (bolts, nuts, washers
etc.), this will cause contact corrosion. The gearbox housing
will be damaged.
♦ The gearbox housing, gearbox cover and cover for final drive
must also all be of the same material.
♦ If you are not sure whether used parts can be re-installed, al‐
ways fit new parts.
Caution
♦ We recommend using only Audi Genuine Parts.
♦ Accessories must be approved by AUDI AG.
♦ Damage resulting from contact corrosion is not covered
by the warranty.
6.2 General repair instructions
WARNING
Prior to performing work with engine running, move selector
lever to position “P” and operate parking brake button to apply
the electronic parking brake.
Proper tools and the maximum possible care and cleanliness are
essential for satisfactory gearbox repairs. The usual basic safety
precautions also naturally apply when carrying out repair work.

pair procedures - which were previously repeated at numerous

⇒ "Special tools, Workshop equipment"
Gearbox
♦ Observe rules for cleanliness when working on gearbox
⇒ page 9 .
♦ The engine must not be run and the vehicle must not be towed
with the end cover removed or without ATF in the gearbox.
♦ Only install clean components: do not remove replacement
parts from packaging until just before installation.
♦ After installing, the following fluid levels must be checked and
topped up if necessary: ATF in planetary gearbox
⇒ page 65 and gear oil in front final drive ⇒ page 97 . Ca‐
pacities and specifications ⇒ page 5
O-rings, oil seals, gaskets
♦ Always install new 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.
♦ Thoroughly clean housing joint surfaces before assembling.
♦ Lightly lubricate the outer circumference and sealing lip of
seals with ATF before installing.
♦ Lightly lubricate O-rings with ATF before installation to prevent
them getting crushed during assembly.
♦ Use only ATF for parts running in ATF. Other lubricants will
cause malfunction of 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 insertion depth tolerances).
♦ After installing, the following fluid levels must be checked and
topped up if necessary: ATF in planetary gearbox
⇒ page 65 and gear oil in front final drive ⇒ page 97 . Ca‐
pacities and specifications ⇒ page 5
Nuts, bolts
♦ Loosen bolts in reverse sequence to the specified tightening
sequence.
♦ Bolts and nuts used to secure covers and housings must be
tightened in steps according to the specified tightening se‐
quence and method.
♦ 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.
♦ The tightening torques stated apply to non-oiled nuts and

♦ Threaded holes which take self-locking bolts or bolts coated
with locking fluid must be cleaned (using a tap or similar). Oth‐
erwise there is a danger of the bolts shearing off the next time
they are removed.
Locking elements
♦ Do not over-stretch circlips.
♦ Always renew circlips which have been damaged or over-
stretched.
♦ Circlips must be properly seated in the base of the groove.
Bearings
♦ Install needle bearings so the lettering (side with thicker metal)
faces towards the installing tool.
♦ Lubricate bearings with gear oil or ATF, depending on fitting
location.
♦ Do not interchange inner or outer races of bearings of the
same size.
♦ Always renew the tapered roller bearings on one shaft togeth‐
er and use new bearings from a single manufacturer.
Shims
♦ Use a micrometer to measure the shims at several points.
Tolerance variations make it possible to obtain the exact shim
thickness required.
♦ Check for burrs and damage. Install only shims which are in
perfect condition.
Guided Fault Finding
Before commencing any repair work, always perform the “Guided
Fault Finding procedure” using vehicle diagnostic, testing and in‐
formation system -VAS 5051 A- .
6.3 Rules for cleanliness when working on
the gearbox
♦ Thoroughly clean all joints and surrounding areas before dis‐
mantling.
♦ Place removed parts on a clean surface and cover them over.
Use sheeting and paper. Use lint-free cloths.
♦ Carefully cover or seal open components if repairs cannot be
carried out immediately.
♦ Only install clean components: do not remove replacement
parts from packaging until just before installation.
