Technical Background
The coaxial connection on the vehicle's main wire harness is not fully connected at the shark fin antenna. This
causes a dampening effect on the signal and creates an intermittent loss of data. Due to the movement of the
coaxial connector, the terminals have been damaged.
Production Solution
Improved FAKRA connector.
Service
1.
Verify the customer concern:
 Verify the customer’s concern in an area with a clear view of the sky. GPS and Satellite radio signals
may not be available in parking structures, areas with tall buildings, and in certain severe weather
situations.
 Perform a 5-minute road test to allow the GPS signal to refresh and lock.
2.
Check DTC fault memory via Guided Fault Finding (GFF):
 If an open circuit DTC is present with an active/static status for either the GPS antenna circuit or the
satellite radio antenna circuit, then locate the source of the open circuit. This TSB only applies to a poor
FAKRA connection at the shark fin antenna.
Note:
The 5F module outputs 5VDC +/- 0.5VDC, carried on the coaxial wiring, and powering the antenna
circuit. An open circuit can be located by checking the coaxial wiring for this 5VDC voltage.
3.
If the customer’s concern is intermittent:
 Wiggle the FAKRA connections and see if the customer's concern can be duplicated. See the applicable
wiring diagram for connector locations as there may be additional connections apart from the 5F and the
antenna connectors.
 If a concern is identified with any connector other than the connector at the shark fin antenna, this TSB
does not apply.

4.
Replace the FAKRA connection at the shark fin
antenna for the applicable circuit, see
instructions below.
Note:
The correct circuit can be identified by the color
on the antenna connector (Figure 1). Not all
antenna connectors are laid out the same:
Satellite radio: Green.
Navigation: Blue.
Figure 1. Identify the correct circuit by the color of the
antenna connector. Blue: Navigation. Green: Satellite
Radio. Connector placement on the antenna will change
by vehicle options, reference the wiring diagram for your
specific vehicle.
5.
Follow instructions located in the repair manual to access the FAKRA connectors at the shark fin antenna.
Only disconnect the FAKRA connector of the circuit associated with the customer’s concern.
6.
Remove a section of the vehicle’s coaxial wiring for the applicable antenna circuit.
Measure the length of coaxial wiring to be removed based on the Adapter Antenna Cable you are using
(Figure 2). This will ensure that the removed section is the same length as the Adapter Antenna Cable (part
number 000098710A or 000098650 (Q7 only)).
Figure 2. Measure the cut point on the vehicle’s antenna coaxial wiring (A) based on the length of the
replacement coaxial “Adapter Antenna Cable” (B). The removed length of cable from A should be equal to
the length of cable B.

 Identify the coaxial wiring type used in your application (RG174 or RTK031).
 Install the applicable replacement aerial connector on the vehicle side of the coaxial harness.
 For a visual example of the coaxial cable with a replacement aerial connector installed see Figure 3,
item A.
Note:
Instructions on how to utilize the VAS6720 are provided in the vehicle repair manual, and with the tool.
8.
Install the applicable connector housing onto the aerial connector installed in the previous step. Ensure the
connector is fully seated onto the coaxial connector and the locking tab is pressed all the way down (Figure
3).
Figure 3. A: Coaxial wire with female replacement aerial connector end installed. B: Insert aerial connector
end into connector housing until fully seated. C: With aerial connector fully seated in the connector housing,
press down on the locking tab. D: Completed assembly.
9.
Install the applicable Adapter Antenna Cable onto the shark fin antenna and connect it to the newly installed
FAKRA connection from the steps 7 and 8. Wrap the new FAKRA connection with cloth tape (part number
000979950) to avoid any unwanted noises.

created FAKRA connection (B). Wrap a layer of cloth tape around FAKRA connection B to avoid any
unwanted noises.
10. Reinstall parts that were removed to access the shark fin antenna as outlined in the repair manual.
11. Clear all DTCs and upload the GFF log to GFF Paperless.
12. Perform a road test and verify the proper functionality of the repaired antenna circuit.
