Condition
• The vehicle is a Q7 or Q3.
• When the vehicle is started, the GPS location or vehicle
direction indicated on the MMI navigation map does not match
the vehicle’s actual location or direction of travel for a long
period of time (often as long as 10 minutes):
• The issue occurs in open sky, with no large buildings
obstructing the sky view.
• The issue is intermittent, but it can occur for long periods
of time during a single day. The issue may or may not
resolve itself.

Figure 1. No satellite reception.

• When the issue occurs, the GPS navigation system
satellite reception shows 0 satellites. Due to the
infrequency of the issue, this might not be verifiable. (To
view the number of satellites being received, go to Nav >>
Route >> Select Current Position (first item in list) and
scroll up (Figure 1)).
• A DTC related to the GPS antenna or MMI system may be or
may not be present
Tip: If the sky view is blocked because the vehicle is in a parking structure, below ground, or next to large
buildings, it is normal for the GPS location or vehicle direction indicated on the MMI navigation map to not match
the vehicle’s actual location or direction of travel. The blocked sky view prevents the vehicle from receiving
satellites, and the system may be temporarily lost (for example, the system may show the wrong location on the
map screen) until four satellites can be received. This behavior can last for several minutes even in clear sky view
when the vehicle exiting a parking structure or underground structure. The MMI can take up to 5-10 minutes to
sufficiently get a 3D-GPS fix once the vehicle has clear view of the sky. This is a normal condition, and is not
related to the condition described above. Replacing the MMI main unit, replacing the GPS antenna, or updating
the MMI software will not change this behavior.

Technical Service Bulletin
Technical Background
A potential antenna hardware failure can affect some model year 2014 - 2015 vehicles.

Production Solution
New GPS antenna hardware was introduced in production starting with calendar week 45 of 2014 (mid-model year
2015).

Service
If the vehicle arrives with a static condition of “0” satellite reception:
1. Move the vehicle outside to a clear view of the sky.
2. Allow the car to sit with the ignition on for at least five minutes, then use the table below to check Measured
Value Blocks 97, 107, and 192 in the information electronics control module 1, J794 (address word 5F).
The “Good Values (Bad Values)” column shows the known good values with the known bad values in
parentheses. The GPS Status, GPS 3D Fix, and number of Received/Used Satellites will be the most helpful
in determining if the MMI is receiving GPS information from the satellites.

Technical Service Bulletin
3. If it is determined that the antenna is potentially faulty, obtain a known good GPS antenna and coaxial cable to
verify that they will fix the issue. Attach the antenna coaxial directly to the back of the MMI main unit using a
service repair coaxial cable (see ETKA using P/N 000 098 650). There are varying lengths that can be
purchased. For instance, P/N 000 098 650 = 300mm/1ft & P/N 00 098 658 = 7000mm/23ft). Then connect the
other end of the coaxial to the test antenna (new service part).
4. Check the MMI to see how many satellites are received with the new antenna. To view the number of satellites
being received, go to Nav >> Route >> Select Current Position (first item in list) and scroll up. If needed,
recheck the Measured Value Blocks and verify the values change to good values.
5. • If it is determined the antenna is faulty, replace the GPS antenna. If the coaxial cable is replaced, order the
correct cable adapter with the 90 degree bend in the connector (See ETKA).
• If the antenna is not determined to be the causal part, continue to diagnose the issue.
