Replacing A Complete Antenna Wire: Procedure

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.

Example: antenna wire from the radio to the antenna is faulty.

-- Separate the connectors of the faulty antenna wiring from their components.

-- Determine the path of the faulty antenna wire in the vehicle and measure the total length of antenna wire to be replaced.

The entire length of the antenna wire consists of the length of the required adapter leads -1 and 3- as well as the connecting wire -2-.

-- Subtract 60 cm from the total length of antenna wire measured, to receive the length of connecting wire required.

-- Obtain the correct length of the required adapter wires and connecting wires as an original replacement part.

-- Cut the connectors off of the faulty antenna wiring.

Leave the rest of the defective antenna wire in the vehicle.

-- Connect the adapter wires to the devices in the vehicle.

-- Provide harness connectors with piece of foam hose to avoid rattle.

-- Route and secure the connecting wire parallel to the old antenna wire.

NOTE: Antenna wires must not be kinked or excessively bent! The bending radius must not be less than 50 mm.

-- Connect the connecting wire with the adapter leads.

-- To prevent rattling noise, provide antenna connectors with a suitable section of foam sheathing.

-- Perform a function test.
