Fig.1     Removing and installing rod aerial

Removing:

• ‒ Disconnect earth strap on bonnet and wing => Fig.2

• ‒ Loosen connector behind the left lower A pillar side trim.
• ‒ Pull aerial cable out into the plenum chamber.
• ‒ Remove left wheel housing liner.
• ‒ → Remove bracket in wheel housing -arrow.
• ‒ Pull aerial out downwards.
• ‒ Release grommet.

Note:

If the aerial is to be replaced, then always use an aerial with a condenser from the genuine spare parts programme (observe part number).

Background:

For VW radio units from 94, the aerial amplifier is supplied with voltage via the aerial signal cable from the radio unit =>see also Self-study programme No. 147.

When installing an aerial without a condenser it is possible that current flow through the aerial cable to earth may lead to excessive corrosion in area of the aerial foot.

Rod aerials with a condenser stop the current flow at the condenser and therefore the body is not damaged.

Installing:

• ‒ Locate grommet and hold in position.
• ‒ Push aerial into grommet.
