Customer states:
 Satellite Radio: Message Displayed “Linking.”
 Satellite Radio: Message Displayed “ANTENNA A technical problem occurred. Please contact your Audi
dealer.”
 GPS: Navigation Location Incorrect.
Technical Background
The coaxial connection on the vehicle 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 movement of the coaxial
connector, the terminals have been damaged.

Production Solution
In preparation.
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 or 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 customers concern can be duplicated. See applicable
wiring diagram for connector locations as there maybe 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 connector and coaxial
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 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 for the shark fin
antenna. Only disconnect the connector for the circuit associated with the customer’s concern.
7.
Cut off a section from the vehicle’s coaxial wiring for the applicable antenna circuit. Make sure the removed
section is the same length as the Adapter Antenna Cable (part number 000098710A). Measure this cut
based off the cabling you receive (Figure 2).
Figure 2. Measure you’re the cut point on the vehicle’s antenna coaxial wiring (A) based off 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.

Utilizing VAS6720 (Aerial Cable Repair Set), identify the coaxial wiring type used in your application (RG174
or RTK031). Reference the vehicle repair manual, or the instructions provided with the VAS6720 and install
a female coaxial terminal onto the vehicle side of the coaxial harness. For visual of coaxial cable with
female coaxial terminal installed (Figure 3, item A).
Utilize the correct female coaxial terminal for the type of coaxial wire in the vehicle. The VAS6720 contains
a tool to identify the coaxial type.
 RG174: 000979910A
 RTK031: 000979910
9.
Install FAKRA connector part number 6Q0035576K onto the female coaxial terminal you installed in the
previous step. Ensure the FAKRA 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 coaxial terminal end installed. B: Insert female coaxial terminal end
into FAKRA connector until fully seated. C: Coaxial female terminal is fully seated in FAKRA connector,
press down the locking tab of the FAKRA connector. D: Completed assembly.
10. Install the Adapter Antenna Cable onto the shark fin antenna and connect it to the newly installed FAKRA
connector from the previous step. 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.
11. Reinstall parts that were removed to access the shark fin antenna as outlined in the repair manual.
12. Clear all DTC’s and upload GFF log to paperless.
13. Perform road test and verify proper functionality of the repaired antenna circuit.
