Update Bulletin2017-11-08. Service bulletin. STRUCTURE; ELECTRICAL SYSTEM. Due to a process fault, the gearbox was filled with ATF fluid containing sulphur on Audi vehicles with multritronic manufactured within a specific period. As a result, a copper sulphide layer may form on the conductor tracks of the gearbox control unit and cause electrical faults. This Update is in effect until removed. Procedure is valid only for vehicles that show the 37H5 code in the Elsa Campaign/Action Information screen on the day of repair. Vehicle must be within the New Vehicle Limited Warranty. Procedure must be performed within the allotted time frame stated in this Technical Service Bulletin. Procedure must be performed on applicable vehicles in dealer inventory prior to sale. Due to a process fault, the gearbox was filled with ATF fluid containing sulphur on Audi vehicles with multritronic manufactured within a specific period. As a result, a copper sulphide layer may form on the conductor tracks of the gearbox control unit and cause electrical faults.
Dealer Letter -2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Due to a process fault, the gearbox was filled with ATF fluid containing sulphur on Audi vehicles with multritronic manufactured within a specific period. As a result, a copper sulphide layer may form on the conductor tracks of the gearbox control unit and cause electrical faults. Drain and flush the gearbox and replace the multitronic unit.
A941442 2034735-2017-11-08. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS. Supersedes Technical Service Bulletin Group 94 number 13-25 dated July 24, 2013. Customer complains about heavy condensation is present in the headlight, lower headlight lens cracking, and upper headlight housing cracking (at transition from lens to black surround). Workshop found no visible external force marks (from accident or debris impact) are present, one or both sides may be affected, and the vehicle is not equipped with halogen headlights. The production process causes stress on the headlights from the bumper, as well as torsional force from installation. The moisture is an optical condition that does not affect the function or performance of the headlights, and it will not lead to corrosion or damage of the internal headlight parts.
A641433 2029714-2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 64 number 12-22 dated July 5, 2012. After one or both of the front door control units (J386/J387) is replaced, one or both of the rear door control units (J3888/J389) cannot be coded or parameterized via an SVM specified vs. actual comparison (spec/actual). The parameter data in the software coding container has changed for the front and rear door control units. As a result, an SVM code is required to update the parameter data for any replacement control unit. Simply running an SVM spec/actual will not code nor update the parameter data in the new replacement control unit. A hardware change suggestion will be provided when an SVM spec/actual is executed. An additional hardware replacement is not required.
A441450 2022563-2017-11-08. Service bulletin. SUSPENSION; STEERING: STEERING WHEEL/HANDLE BAR. Supersedes Technical Service Bulletin Group 44 number 14-49 dated April 17, 2014.

The customer feels the vibration while driving at highway speeds from 55 ? 80 mph (88 ? 128 km/h). This bulletin is not applicable if this vehicle has a Repair Authorization on this topic. If an applicable Repair Authorization is not followed, the claim will not be paid. The vibrations felt by the customer could be a result of the harmonic vibrations caused by the radial force variation (RFV) of the tires or an imbalance of the wheel and tire assembly.
A371430 2003658-2017-11-08. Service bulletin. POWER TRAIN:CLUTCH ASSEMBLY:PEDAL/HAND LEVER(MOTORCYCLE). Supersedes Technical Service Bulletin Group 37 number 13-07 dated May 29, 2013. Customer states that the engine returns to idle speed of approximately 1,400 RPM although the accelerator is depressed, and/or the vehicle hesitates (lacks power on take-off). No DTCs are stored. This condition may be caused when the brake pedal and the accelerator pedal are depressed simultaneously. Drivers who drive with their left foot resting on the brake pedal are prone to experience this condition.

Customer may report transmission warning light is illuminated. In some cases, the vehicle will not move after being started and placed into gear. After key cycle, the vehicle drives without restriction. DTCs are stored in the transmission control module (TCM). If DFCCs do not match exactly, this TSB does not apply. The DTCs are stored due to an issue with the transmission control module software.
A371424 2037127-2017-11-08. Service bulletin. VEHICLE SPEED CONTROL:ACCELERATOR PEDAL. A jerky accelerator response is felt when the vehicle is pulled away from a stop in reverse. Incorrect calibration of clutch program.

Transmission warning may appear in instrument cluster. After ignition cycle, the warning message is no longer present. DTC P074100 (Torque Converter Clutch Circuit Performance) or ?Stuck Off? is stored in transmission control module (TCM), J217 (address word 03). The fault occurs with ATF temperature below 60o C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks.
A011479 2033379-2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 01 number 13-42 dated November 21, 2013. DTC P164D00 is stored in the engine control module. Red oil pressure warning light may be on. An oil filter that is too short is installed. The oil filter must be 155 (+/-1) mm long. If the oil filter is too short, the drain flap in the oil filter housing will not be completely closed and oil pressure will be reduced.
A011477 2030580-2017-11-08. Service bulletin. ELECTRICAL SYSTEM:STARTER ASSEMBLY. Supersedes Technical Service Bulletin Group 01 number 14-51 dated January 3, 2014.

A001463 2033576-2017-11-08. Service bulletin. ENGINE; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Supersedes Technical Service Bulletin Group 00 number 13-49 dated May 14, 2013. Although the correct amount of oil was added to the engine during an oil change service, a check of the oil level shows that the oil level is not okay. When an unapproved aftermarket speed-filling device is used to add oil to the engine, the increased oil flow rate may force oil into the intake manifold or combustion chamber, creating the potential for engine damage.
A741420 2035757-2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL; SEATS. Supersedes Technical Service Bulletin Group 74 number 14-17 dated February 21, 2014. Customer may complain that the seat pneumatics (side bolsters and lumbar support) actuate without any input from the customer. This condition can occur when the vehicle is driven at high altitudes or when the outside temperature fluctuates. DTCs may be present in the front seat pneumatics control modules, J873 and J872 (address words 88 and 89) or in the rear seat pneumatics control modules (in certain A8 models only), J875 and J874 (address words 8A and 8D). No leak is present. There is a software issue in the seat pneumatics control modules that causes the seat pneumatics to automatically actuate in high altitudes (change in air pressure) or in fluctuating temperatures in order to maintain pressure.
A201434 2035073-2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 20 number 14-32 dated March 21, 2014. The MIL is on.

A971443 2036764-2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 97 number 14-42 dated March 31, 2014. The MIL is on. Vehicle will not start. DTC P068A00 is stored in the ECM. The motronic engine control module power supply relay, J271, is not functioning properly. Because the J271 relay controls battery voltage (Terminal 30) via a ground signal sent from the ECM, numerous faults can occur in multiple control modules when it is not functioning properly.
