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.
