^
Base is more oval in shape than Bosch (approx. 61 mm x 41 mm).
^
Two screws on underside of base are painted.
^
Requires matte finish antenna mast.
If antenna mast matches the antenna base correctly:
-
Check antenna and connections
Antenna cable and connections, checking
-
Check antenna coaxial cable connections -arrows- for corrosion and clean if necessary (DO NOT apply stabilant). Passat coaxial cable connection
for radio is under the carpet on right side of tunnel near shifter.
Note:
DO NOT Check the antenna system by using an ohmmeter from the antenna lead to the threads where the mast -1- attaches to the base of the antenna.
This will not work because the antenna system uses an amplified signal.
-
Ensure that coaxial cable is firmly seated in radio (Passat cable connection, see previous step).
-
Check ground at the antenna below roof Nut -4- (torque = 7+1 Nm) must firmly secure antenna to roof).
-
Check ground for radio behind radio on cross member (On Passat models as of Nov. 1998 beginning VIN: XE285000 ground for radio is on right
side of center tunnel).
-
Check engine compartment ground, left side, below battery tray; from battery GND to body.
-
Check engine/transmission ground on transmission, near engine block.
-
If all grounds and antenna mast are OK.
-
Replace antenna and coaxial cable assembly.
