1.1 General Repair Information
To ensure perfect and successful transmission repairs, the great‐
est care and cleanliness as well as the use of good and proper
tools is essential. The usual basic safety precautions also apply
when carrying out vehicle repairs.
A number of generally applicable instructions for individual repair
operations, which are otherwise mentioned at various points in
this repair manual, are summarized under the term “components”
⇒ page 1 .
1.2 Components
Rear Final Drive
♦ Allocate bolts and other components according to final drive
code using the ⇒ Electronic parts catalog .
♦ When installing a new rear final drive unit, check the oil level
in the rear final drive and top up if necessary ⇒ page 6 .
♦ Capacities and specifications, Audi A4 ⇒ page 5 .
♦ Capacities and specifications, Audi A5 Coupe ⇒ page 5 .
♦ Clean contact surfaces when repairing mounting brackets and
waxed components. Contact surfaces must be completely free
of oil and grease.
♦ Thoroughly clean all connections and the surrounding area
before disconnecting.
O-Rings, Gaskets, Seals
♦ O-rings, gaskets and seals must be replaced.
♦ After removing gaskets and seals, always inspect the contact
surfaces at housing or shaft for burrs resulting from removal,
or for other signs of damage.
♦ Thoroughly clean housing joint surfaces before assembling.
♦ Before installing radial shaft seals, lightly oil outer circumfer‐
ence and fill space between sealing lips -arrow- halfway with
sealing grease -G 052 128 A1- .
♦ The open side of the gaskets points toward the fluid to be
sealed in.
♦ Lightly lubricate O-rings before installing to prevent them from
being crushed when inserting.
♦ When replacing seals and gaskets, check the oil level in the
rear final drive and fill if necessary ⇒ page 6 .

♦ Always replace damaged or over stretched circlips.
♦ Circlips must locate properly in the groove.
♦ Replace spring pins. Installation position: Slit -A- should be in
line with the line of force-arrow-.
Bolts and Nuts
♦ Loosen and tighten the cover and housing mounting bolts or
nuts in a diagonal sequence.
♦ Delicate parts must not be cross-threaded. Loosen and tighten
in stages in a diagonal sequence.
♦ The tightening specifications stated apply to non-oiled nuts
and bolts.
♦ Replace self-locking bolts and nuts.
♦ Clean threads of bolts that were applied with locking fluid using
a wire brush (does not apply to driveshaft bolts: these must be
replaced). Then insert bolts with locking fluid -
AMV 185 101 A1- .
♦ Threaded holes into which self locking bolts or bolts coated
with locking fluid are installed, must be cleaned (e.g. tap).
Otherwise there is a risk that the bolts will shear the next time
they are removed.
