The new generation of A4.2 automatic transmission is fitted with monoblock wiring which means that many
of the intermediate connectors are no longer required. As a result, the method for repairing sensors or
switches is different.

REPAIRING COMPONENTS
Most of the components comprising the mono-
block wiring are not directly interchangeable.
Only the pressure sensor can be replaced without
having to cut the cable.
REPAIRING THE MULTIFUNCTION SWITCH
Initially, this is checked with the 55 track connec-
tor using the bornier Sus. 1228 and the table be-
low.
If this checking procedure highlights a fault, sec-
tion the cable 15 cm from the switch and check
between the section and the 55 track connector.
See the wiring diagram and table below. If one of the insulations or one of the continuities
is not assured, replace the multifunction switch
and refer to note 8074 for the repair procedure.
Refer to notes 8074 and 8075 for repairing the
speed sensor and using the locally made lifting
plate.

Removing the wiring assembly is specific to the
AD4 A4.2.
REMOVAL
Put the vehicle on a two post lift.
Disconnect the battery.
Remove the front left hand wheel.
From the wheel arch:
Remove:
- the earth wire from the multifunction sensor,
- the multifunction sensor mounting bolt (A).
On the vehicle:
- position the lifting plate (tool made locally as
described on the next page).

Remove the engine torque traction link on the
gearbox side.
Remove the speed sensor (mounting bolt (B)).
Remove gear selector control ball joint (C).
Remove all the wiring assembly, taking note of its
position and mountings so that is refitted
correctly.
Disconnect the 52 track connector and the
connector in the inter engine unit. Fit the engine support tool with the support
bracket on the left hand side.

There are two possible solutions for manufactu-
ring this plate.
1)By modifying the existing plate on the E7J en-
gine (air filter support plate mounted onto the
cylinder head).
2)By having it manufactured locally
Parts list: - 1 plate of thickness 4 or
5 mm in semi-hard steel,
-
2 HEX M8 × 20 bolts (collar
bolts).

Disconnect the connectors from the pressure sen-
sor and the diagnostic/injection socket.
Disconnect the sealed connector switch.
Remove the wiring.
99613S2
REFITTING
Replace the wiring without securing it.
Refit:
- the speed sensor,
- the multifunction sensor.
Refit the mounting on the gearbox side.
Remove the engine support tool.
Reconnect all the components.
Secure the wiring using its clips.
