Repairing aerial wires
Repairing aerial wires
A repair method has been developed for repairing aerial wires. Instead of a complete aerial wire, connecting wires of different lengths and various adapter wires are now available as replacement parts.
Replacement parts → Electronic parts catalogue; Special catalogue „Electrical connecting elements“; Accessories; Sub-group 35 from chart 035-20 onwards.
  Note
t  Do not repair aerial wires. The wiring must be renewed using connecting wires and adapter wires (available as genuine replacement parts).
t  These genuine replacement parts are suitable for all wire cross-sections and aerial wires which have to be renewed.
t  It is not possible to renew individual aerial connectors during repair work.
t  The replacement wires can be used for all previously fitted wiring cross-sections on all Audi models.
t  All adapter wires and connecting wires are suitable for all transmission and reception signals.
t  The repair method can also be used for testing and service installation purposes (e.g. retrofitting).
Special tools and workshop equipment required
   
t  -1- Adapter wire for connection to radio; length: approx. 30 cm
t  -2- Connecting wire; various lengths available
t  -3- Adapter wire for connection to aerial; length: approx. 30 cm
Procedure
Example: Aerial wire from radio to aerial defective
–  Unplug connectors of defective aerial wire from units.
–  Determine routing of defective aerial wire in vehicle and measure out overall length of aerial connection to be replaced in vehicle.
  N97-0424
l  Total length of aerial connection = length of required adapter wires -1 and 3- plus connecting wire -2-.
–  Subtract 60 cm from total length of aerial connection measured to calculate required length of connecting wire needed.
–  Obtain necessary adapter wires and connecting wire (with calculated length) as genuine replacement parts → Electronic parts catalogue.
–  Cut connectors off defective aerial wire.
l  Leave rest of defective aerial wire in vehicle.
–  Connect adapter wires to units in vehicle.
–  Fit connectors with a piece of foam sheathing to prevent rattling noise.
–  Lay and secure connecting wire parallel to old aerial wire.
  Note
Aerial wires must not be kinked or bent excessively. Bending radius must not be less than 50 mm.
–  Attach connecting wire to adapter wires.
–  To prevent rattling noises, apply a suitable piece of foam sheathing to aerial connectors.
–  Check operation.
