January 21, 2011.

Supersedes Technical Service Bulletin Group 38 number 10 - 01 dated March 19, 2010 for the reasons listed below.

AFFECTED VEHICLES

CONDITION

Customer may report:

^ At startup, intermittent no drive when selecting driving mode D or R.

^ The vehicle can be driven only in 3rd gear (Limp Home Mode).

Workshop findings:

^ In rare circumstances, if the vehicle was in motion and the ATF strainer becomes loose, the transmission may go into Limp Mode and can be

241

driven in only 3rd gear.

^ In cold conditions, the gearbox shifts with a delay. In hot conditions, suction noises occur.

^ The following DTCs may be stored in the transmission control unit:

^ DTC P0730 (Transmission monitoring incorrect gear ratio)

^ DTC P2700 (Clutch A implausible)

^ DTC P2701 (Clutch B implausible)

^ DTC P2702 (Clutch C implausible)

^ DTC P2703 (Clutch D implausible)

TECHNICAL BACKGROUND

Because of a design change, the ATF strainer can come loose from the guide of the ATF pump intake duct. As a result, air can be drawn in. Air

causes the oil to foam, which prevents the clutches from closing completely.

PRODUCTION SOLUTION

Optimized ATF filter.

SERVICE

If the complaint can be reproduced, proceed as follows:

1. Check the gearbox control unit for the above entries and create a diagnosis protocol.

^ If there are no faults stored but the concern can be duplicated; proceed to step 2.

^ If one or more of the above DTCs are stored, proceed to step 3.

2. Check the ATF level per ELSA instructions.

^ If the fluid level seems too high and foamy due to air mixed with the ATF, proceed to step 3.

^ If the fluid is at the correct level and the fluid is not foamy, open a Technical Assistance Center (TAC) ticket and contact a TAC representative.

3. Drain the ATF into a clean container and remove the ATF pan.

Tip: Catch the ATF in a clean container and reuse it after the repair.

4. If the filter was found in the bottom of the pan, proceed to step 6.

5. If the filter is still seated in the valve body, try to remove it with light force.

^ When removed, if the filter seal remained behind in the valve body or is not fully installed on the neck of the filter, proceed to step 6.

242

^ If the seal is fully installed on the filter as shown in Figure 1, open a TAC ticket and contact a TAC representative.

6. Replace the ATF filter with a new filter according to the Repair Manual.

Note:

Make sure that the magnets in the oil sump are not stuck on the underside (metal side) of the loose ATF filter and are not removed with the old

strainer. The magnets must be reinstalled in the pan to protect the transmission from metallic particle abrasion in their correct original location.

7. If there are complaints of gear shift quality after replacing the ATF filter, clear the adaptations in the test plan and then perform the GFF or

Guided Functions Adaptation Drive.

Electrical - No Start Due To Discharged Battery

27 Low Battery Charge: Excess Current Draw Location

27 12 13

2029010/1

March 22, 2012.

Affected Vehicles

Condition

The customer may report a discharged battery when trying to start the vehicle. Condition results in a no start.

Technical Background

Not applicable.

Production Solution

Not applicable.

Service

1. If the vehicle is equipped with Battery Energy Manager (J644) or Battery Diagnostic Manager (J367), please perform TSB 2025360, 27 Low

Battery Charge: Diagnosis Tips and TAC Instructions before continuing with this bulletin.

2. Verify the battery is good, using one of the below TSBs, depending on vehicle equipment:

^ TSB 2023282, 27 Battery testing and charging - vehicles with BDM (J367)

^ TSB 2023330, 27 Battery testing and charging - vehicles with BEM (J644)

^ TSB 2023266, 27 Battery testing and charging - vehicles without BDM or BEM

3. If the battery is defective, replace as per the instructions in the applicable TSB.

4. Determine if a draw currently exists on the vehicle by using an ammeter with an inductive pickup, such as the 5051B, or similar tool, such as a

Fluke Meter, to check battery draw using the steps below:

a. Start vehicle and operate all consumers on vehicle (radio, lights, heated seats, door locks, sunroof, power liftgate, etc.)

b. Shut off vehicle, open left and right front doors, hood, and rear lid. Manually latch all opened items to gain access to fuse boxes.

c. Zero the ammeter and attached the amp clamp to the negative battery cable. Lock the car using the remote and observe the ammeter, which

should spike briefly as the doors are closed. This will confirm the ammeter is operating correctly. The vehicle may also provide a confirmation

beep to confirm all doors are latched, provided the option is enabled in the MMI (if applicable).

d. After 2 hours, the ammeter should read under 0.040A (40mA).

If the reading is above 40mA, attempt to locate the source of the excessive draw by proceeding to step 4.

If vehicle does not exceed maximum sleep state current draw, perform a long term (overnight) measurement test. Record the long term

measurement using MIN/MAX setting of scan tool. If the long term measurement still does not exceed the maximum sleep state current draw,

proceed to step 10.

Tip: Periodic spikes in current draw are normal.

5. To determine the potential source if the current draw, measure the voltage drop across the vehicle fuses using the VAS Scantool multimeter, Fluke

multimeter, or equivalent.

6. Using the "mV" scale on the multimeter, measure the voltage drop across fuses by placing the positive lead on one side of the fuse, and the

negative lead on the other (Figure 1). Take absolute value of reading of voltage drop (ignore negative signs) and then reference voltage drop chart to

determine how much current the circuit is currently consuming. See Identifying Cuffent Consumption with Matrix attachment.

Tip: Due to the operation of CAN Bus communications, it is no longer possible to simply pull fuses to determine the location of a draw, as this

action can result in a bus wakeup and invalidate the test.

41

7. Continue this process until the fuse with an inappropriate amount of draw (over 40mA) is discovered.

8. Once fused circuit is identified, use service repair and wiring diagram information in ElsaWeb to identify all components on that circuit.

Disconnect the components from the circuit one by one and allow the sleep current to stabilize after each disconnection.

9. Measure the vehicle current consumption and voltage drop across the fuse again. If the values are now within the normal range, the component

causing excess draw has been identified. If the values are still too high, repeat steps 5-7 again until the component is identified.

10. If it is necessary to contact TAC for additional guidance, please prepare the following information before opening a contact. If TAC assistance is

not necessary, proceed to the next step.

^ How many times is car in for a battery concern?

^ When did the vehicle come in?

^ Was it towed in or jumped?

^ What day did the customer have the concern?

^ Is/was the date/time in cluster correct? If not, what was/is the date/time displayed?

^ When did you start working on the car?

^ What is the battery serial number in the vehicle?

^ Are there any other electrical concerns on the R.O.?

^ Attach a full GFF Log with complete battery history data and Keep Awake readout (For vehicles equipped with J367).

^ Attach pictures of the amplifier for Audi Q7, A4 Avant, or A6 Avant vehicles if the amplifier shows no obvious signs of water damage.

11. Before returning the vehicle to the customer, test the battery state of charge and verify that it is above 85%. If the SOC is below this value,

charge the battery until at least 85% is achieved.

2018194/4

April 1, 2010.

Supersedes Technical Service Bulletin Group 40 number 09-04 dated June 17, 2009 for reasons listed below.

318

Affected Vehicles

Condition

One or several shock absorbers have an oil coating.

Technical Background

---

Production Solution

---

Service

This information is designed to help you assess whether a shock absorber is leaking.

Leaking shock absorbers

A leaking shock absorber is characterized by a wet film of oil running down the pipe. This needs to be replaced.

319

Shock absorbers with oil marks

A light film of dried oil or oil marks on the pipe beneath the dust guard are not clear indication of a leaking shock. These are caused by residues

from filling up the shock during production or slight "condensation" in the seal area. This small amount of oil is for lubrication and reduces the wear

of the seal.

Tip: This does not affect the shock absorber. No repair is necessary.

Tip: For further information see the repair manual under "Shock absorbers, checking."

March 27, 2013

Supersedes Technical Service Bulletin Group 57 number 12-80 dated November 9, 2012 for reasons listed below.

473

Vehicle Information

Condition

The door cannot be opened from outside with the outer door handle, but it can be opened with the inner handle. The complaint is often described as

follows: The customer locks the vehicle and checks by pulling the door handle whether the vehicle is locked. When opening the vehicle again, the

door cannot be opened. It feels as if the handle is slack.

474

Technical Background

When fitting the Bowden cable from the mounting bar to the door lock, the cable can get kinked. In some cases, this can increase the inner friction of

the strand in the Bowden cable. As a result, the door lock stays in pressed position or does not completely return to its zero position (Figure 1).

When the Bowden cable gets twisted during the installation, the rubber grommets can get distorted. Consequently, the Bowden cable has a too-high

inner friction and the door lock does not move to the zero position (Figure 2).

Improved cable with 'L'-shaped attachment (Figure 3). Improved positioning of the locking collar.

Service

1. Replace the cable. The bow does not need to be replaced unless damage to the component is evident. Remove/install the latch carrier ("bow"

according to ETKA) and Bowden cable together, as a set, according to the repair manual:

Repair Manual >> Body >> Body Exterior >> 57 Front doors, Central Locking System >> Removal and Installation >> Door Components >>

475

Door Lock, Bracket, Door Lock Actuating Link.

April 24, 2012.

Supersedes Technical Service Bulletin Group 87 number 10 - 03 dated June 16, 2010 for reasons listed below.

Affected Vehicles

31

Condition

Unpleasant "musty" odor from heating and ventilation system. Odor mainly occurs after vehicle has been sitting unused at least 5 hours and within

20 to 60 seconds after vehicle is first started.

Technical Background

Condensate is a normal condition in all A/C systems. If odor is noticeable without engine started, this may be due to mold and mildew in the

passenger compartment, not from the A/C system. All other possible sources of unpleasant odor must be addressed before performing this Technical

Service Bulletin. Consider the following conditions before proceeding:

^ Evaporator housing drain must be open and free of debris.

^ Cabin must be sealed with no water ingress into the passenger compartment.

^ Plenum drains must be clear and free of debris.

^ Pollen filter must be clean and free of moisture.

Contaminants are effectively neutralized using the Aircomatic(R) II Ultrasonic Climate System Cleaner (VAS 6189A) and Airco-Clean(R)

Ultrasonic Air Conditioning Treatment (VAS 6189/1). All other cleaning methods are no longer permitted.

Production Solution

Not applicable.

Service

1. If the vehicle is equipped with a pollen filter that is located inside the cabin such as in the A3, A6 and Audi Q7 then the pollen filter element

will need to be removed and its cover reinstalled before performing this procedure.

2. Start engine.

3. Set climate control temperature to its lowest setting. Set fan speed to its lowest setting. Set airflow direction to the dash vents only. Activate

recirculation and ECON modes.

32

4. Thoroughly shake a 100ml bottle of treatment and empty the bottle into the filling chamber.

5. Connect the outlet tube.

6. Place the cleaning unit into the passenger footwell, making certain that the unit is as level as possible. Connect the power cord and route it

through a slightly opened window. The remaining windows and sunroof should be completely closed.

7. Switch unit on and position the outlet tube such that the vapor is drawn into the recirculation air intake, generally in the passenger footwell

area. Refer to the appropriate repair information for exact location. Close all doors. The atomized cleaning fluid will begin coming out of the

vents. After about 15-20 minutes, the treatment stops automatically.

33

8. If the vehicle is an Audi Q7 with 4 zone climate control, the rear A/C unit is to be treated as well. Repeat the procedure for the rear A/C unit.

Use the same A/C settings as were used for the front A/C unit. Position the outlet tube toward the vent on the left of the rear compartment.

9. Air out the vehicle after the procedure for about 10 minutes.

10. Check the Aircomatic manual for instructions for unit maintenance after each use.

A/T, Drivetrain - Vibrations On Tight Turns

37 Vibrations on tight turns

39 10 03

2022896/1

June 29, 2010

Affected Vehicles

Condition

Customer may report vibrations, humming noises or rubbing noises from the drivetrain when driving slowly around very tight turns. The noise is

particularly noticeable when maneuvering at full steering wheel lock in a parking lot.

Technical Background

Friction-reducing additives in the differential oil are reduced by wear. At high load on tight turns, the friction discs and worm wheel teeth in the

351

center differential are subject to wear.

This changes the friction and locking values in the center differential and causes vibrations in the drivetrain.

Production Solution

Service

Test drive the vehicle.

^ Light vibrations at full steering wheel lock are normal.

^ With stronger than normal vibrations in minor corners or heavy vibration at full steering wheel lock, proceed as follows:

a. Check the center differential according to the repair manual for correct oil level and inspect for damage (metal shavings).

b. Ensure the wheels are not damaged (bent) and all four tires are the correct size and the same type of tire.

c. If nothing is found, change the oil of the center differential with G 055 145 A2.

The center differential does not have a drain plug, therefore the gear oil can be drained only by removing the cover.

Follow the repair manual directions for removal and installation of the Self-Locking Center Differential Cover but only remove the cover far

enough to drain the oil. Then reassemble and fill with the new G 055 145 A2 oil.

d. Drive the vehicle along a lot of bends until the gearbox temperature reaches 80锟斤拷C and reassess the vibrations.

- If the vibrations have been reduced to normal, the concern is repaired.

- If the oil change does not repair the concern, submit a Technical Assistance Center ticket under the Concern Type: Audi Automatic

Transmission.

Affected Vehicles

Condition

One or more of the following complaints are reported by the customer regarding electrical features and functions in the vehicle:

^ One or more warning lights on in cluster

^ The DIS or other displays in cluster are blank

^ MMI does not function

^ Windows do not function

^ LED indicators in various buttons inside the vehicle do not light up

Technical Background

9

The voltage regulator on the alternator (Figure 1) can sporadically fail causing the electrical system to experience too high of voltage. As a result, the

affected vehicle electronic components go in to high voltage protection and deactivate sensitive displays and indicators to prevent electrical damage.

When an over voltage condition occurs the vehicle electronics and alternator are protected, thus there is no need to replace the entire alternator

assembly.

Production Solution

A new VDA voltage regulator with better control over the alternator voltage was introduced in to series production.

Service

Check for DTC entries for excessive voltage.

1. These DTCs are only set when a control unit sees input voltages higher than 18V for extended periods of time.

^ DTC 00447 (Functions restriction due to excessive voltage - Upper limit exceeded)

^ DTC U140100 (Function restriction due to excessive voltage)

^ DTC P056300 (System Voltage High Voltage)

2. If more than one over voltage DTC is present in multiple vehicle electronic control units then proceed with the repair suggested in this service

bulletin.

3. If only one control unit on the vehicle is displaying an over voltage DTC then this service bulletin may not apply.

4. If no DTCs are present in any electronic control unit but the customer complains of lights flickering or going dim/bright intermittently, then

please reference TSB 2021151, 91 Dash insert, air conditioning control panel or inside light flickers for additional information.

December 18, 2009

Affected Vehicles

Condition

MIL on and one or more of the following DTCs are stored in the ECM data memory:

^ P310B (Low-pressure fuel system regulation, fuel pressure outside tolerance)

^ P129F or P008B (low-pressure fuel system, pressure too high)

315

^ P129E or P008A (low pressure fuel system, pressure too low)

^ P2540 (low pressure fuel system, pressure out of range)

^ P0087 (rail fuel pressure system, pressure too low)

Technical Background

Comparing Measure Value Block 103 with 106 is not an accurate method to diagnose low-side fuel pressure sensor G410.

In order to diagnose G410 accurately, use a mechanical gauge and compare results with the low-side fuel pressure Actual Value in the applicable

Measured Value Block (varies by engine).

Production Solution

Not applicable.

Service

1. Verify the customer did not run out of fuel at the time the DTCs were stored.

Tip:

P310B and/or P129E / P008A may be accompanied by P1250. If so, it is likely the faults occurred due to a low fuel level and not a malfunction of

the G410 Pressure Sensor.

2. Follow indication of GFF for applicable DTCs.

3. To check the low-side fuel pressure sensor G410, measure the fuel pressure with a mechanical gauge using the following method:

a. Start engine and allow to idle for at least one minute.

b. Stop the engine.

c. Keep the ignition on.

d. Measure actual low-side fuel pressure via mechanical gauge (VAG 1318) on the low pressure supply line in the engine compartment (Figure 1).

4. Add 1 bar to the value obtained from the mechanical gauge to calculate the adjusted gauge measurement value.

5. Compare the adjusted gauge measurement value to the Actual Value stored in the applicable low pressure MVB.

Tip:

In some cases, the MVB actual value is shown in hPa instead of bar. For comparison, 1 bar = 1000 hPa; (5000 hPa = 5 bar).

6. If the MVB value deviates more than ?.0 bar from the adjusted gauge measurement value, then the DTC was likely triggered by a faulty G410

low-side fuel pressure sensor. In this case, document the adjusted gauge measurement value and MVB value on the Repair Order and perform the

Sensor replacement procedure below.

316

Sensor replacement procedure

1. Replace the G410 low-side fuel pressure sensor.

2. Clear DTCs and verify that the problem was eliminated.

3. If applicable, run Basic Settings to adapt low-side pressure system.

4. Do not replace the high pressure fuel pump, electrical fuel pump, fuel pump control module or fuel filter unless problem persists and further

diagnosis indicates a malfunction of any of these components.
