Technical Service Bulletin
• 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.
Figure 1. No satellite reception.
• The issue is intermittent, but it can occur for long periods of time during a single day. The issue resolves itself
intermittently.
• The issue typically happens on very warm days when the HVAC system blower is at a medium to high
setting (auto or manual), with air being directed out of the panel vents.
• 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)).
• No DTCs related to the GPS antenna or MMI system are present.
• The vehicle is an A4 (including S4 and allroad variants), A5 (including Cabriolet, S5, and RS 5 variants), A6
(including S6 variant), A7 (including S7/RS 7 variants), A8 (including long wheelbase, S8, or W12 variants) or
Q5 (including SQ5 and hybrid variants). (Q7 and Q3 vehicles are not affected by this condition. See TSB
2030465, 91 MMI3G+ GPS navigation location inaccurate or navigation takes a very long time to acquire
location (Q7 or Q3) for Q7 and Q3 vehicles.)
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 is 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 Background
A potential failure in the MMI software (in model year 2013 vehicles) or a failure in the internal hardware of the
MMI main unit (in model year 2013 - 2015 vehicles) can cause the GPS signal to be blocked, even if good
reception is available (clear sky with clear view of sky). The failure can happen at start-up or while the vehicle is
being driven. The issue typically starts when the vehicle is driven on curvy or circular roads, driven in circles (such
as when driven around a parking lot), or driven on or off an expressway.
Additionally, there is a potential antenna hardware failure that can affect some model year 2014 - 2015 vehicles. It
is important to check the antenna before replacing the MMI main unit.

Production Solution
• New software was introduced in production starting calendar week 22 of 2013 (start of model year 2014
production).
• New hardware was introduced in production starting with calendar week 45 of 2014 (mid-model year 2015
production).
• New GPS antenna hardware introduced in production starting with calendar week 45 of 2014 (mid-model year
2015 production).
Service
Follow one of the repair options below.
Repair Option 1:
Updating the MMI software for model year 2013 vehicles with good satellite reception
If the vehicle arrives with good satellite reception, shows at least four satellites as being received, and is a model
year 2013 vehicle:
• Check the MMI ZUG version in the MMI (Menu>>Setup MMI>>Software Versions).
• If the value shows anything less than K0715 (such as P0566), update the MMI software only.
• If the software is already updated to K0715 or later (such as K0814), proceed to “Repair Option 3:
Replacing the MMI main unit”.
1. Update the MMI software using ZUG K0814 (see TSB 2030465: 91 MMI 3G+ Various technical Issues (K0814
ZUG update; supersedes K0715 update)).
2. Perform the required SVM feedback according to the instructions in TSB 2030465:
• A4, A5, Q5 use SVM code 3GPUS814AU3G
• A6, A7, A8 use SVM code 3GPUS814
The required SVM code is also included in the ZUG K0814 update medium.
Repair Option 2:
Checking satellite antenna for all vehicles with static “0” satellite reception condition
If the vehicle arrives with a static condition of “0” satellite reception, first verify that the antenna is not the root
cause of the condition:
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

This will show the date when the “0”
satellite condition started.
MVB 192.2
0 Satellite Condition Start Time of Day This will show the time of day when
the “0” satellite condition started.
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 part number 000 098 650). There are varying lengths that can be
purchased. For instance, part number 000 098 650 = 300mm/1ft and part number 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).
Repair Option 3:
Replacing the MMI main unit for all vehicles with “0” satellite reception and a good antenna or for model
year 2013 vehicles with K0814 software and intermittent GPS reception
If it is determined that the antenna is not the causal part for the concern, perform the following repair steps for the
MMI main unit:
1. Update the MMI software using ZUG K0814 (see TSB 2030465: 91 MMI 3G+ Various technical Issues (K0814
ZUG update; supersedes K0715 update)).

Tip: This update ensures that the MMI control panel (E380) will be able to communicate with the new
MMI main unit (J794). If the update is not performed, the MMI control panel button LED lights will flash
constantly to indicate a software incompatibility in the MMI main unit.
2. Perform the required SVM feedback according to the instructions in TSB 2030465:
• A4, A5, Q5 use SVM code 3GPUS814AU3G
• A6, A7, A8 use SVM code 3GPUS814
The required SVM code is also included in the ZUG K0814 update medium.

translucent yellow coating (Figure 2).
Some early service parts did not have the coating despite the updated hardware part number (G suffix) and
build date. All parts built after November 08, 2014 should have the coating over the integrated circuit chip. If
the part does not have the coating over the integrated circuit chip, return the part and order a replacement.
If the parts department has problems getting updated parts with the integrated circuit chip coating, contact
TAC. A small amount of specially modified parts are available for shipping directly from Audi of America.
4. Check the label (Figure 3) on the side of the new
part to verify that it contains software at level 0901
or higher. Install the replacement MMI main unit
(information electronics control module 1, J794
(address word 5F)).
Figure 3. Main unit part label.
5. • If the software level is less than 0901, perform component protection removal, repeat steps 1 and 2 and
then move to step 6.
• If the software is at 0901 or above (A6, A7, and A8 can have 0902), perform component protection removal
and repeat step 2, then move to Step 6. Repeating step 2 will allow SVM to accept the new control unit
with the updated part number.
6. Complete the GFF replacement test plan for the information electronics control module 1, J794 (address word
5F) with only the new MMI main unit installed in the vehicle (the original MMI main unit is not needed).

Ensure that the new coding, new parameterization, component protection removal, and the recovery activation
(for navigation activation) are all completed successfully before returning the vehicle to the customer. If, at any
time, an error that cannot be corrected appears, contact the Technical Assistance Center (TAC) for further
assistance.
7. If the SVM communication fails with a “check hardware” response, and the DTC for “Checking Software
Version Management” is in the 5F fault memory, contact TAC. If the lights flash after the repair is complete, try
a hard reset by pulling the quad lock connector from the main unit while ignition is on and reconnect. If this
doesn’t resolve the concern, contact TAC for further assistance.
