The battery in the handheld transmitter may be too weak for a good signal. The battery charge may be sufficient to operate the garage door opener, but not enough to program the remote transmitter to the vehicle system. In A4 model years 2005?2006 and A3 model year 2009, the actual location of the garage door opener control module differs from the location shown in the owner's manual (opposite side of front bumper). The customer may misunderstand the programming procedure, particularly if the customer?s HomeLink® opener system is using an alternate code. The handheld transmitter?s programming function may become inoperative, or the transmitter is too far away from J530. Interference prevents the communication between handheld transmitter and J530. Interference prevents the communication between handheld transmitter and J530. If the vehicle flashes during the programming of a handheld transmitter, this does not necessarily indicate that the programming was successful; it only indicates that the vehicle has recognized and saved a signal. |

| A461226 2031135- | 2017-11-08. Service bulletin. LANE DEPARTURE; PARKING BRAKE; ELECTRICAL SYSTEM. The customer may state the yellow warning for electric parking brake (EPB) appeared once in the instrument cluster, but the warning turned OFF after cycling the ignition and there have been no additional occurrences. The customer may state the adaptive cruise control (ACC) was inoperative once, but resumed operating properly after cycling the ignition and there have been no additional occurrences. DTC is stored in the EPB module. Internal code Param_InterFaultID 24 or 25 may be in the extended environmental conditions. The concern is due to a software glitch in the EPB control module. Concerns related to this software glitch can only occur once. Replacing the EPB module may cause an additional occurrence. |
| A911263 2021151- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 91 number 11 ? 83 dated April 15, 2011. The customer may report that the illumination of the dash insert, the air conditioning control panel or the inside light flickers when briefly pressing the accelerator in P or N or when shifting down while driving downhill. Only vehicles with PR number 8GH may be affected. When high electricity consumers are switched off and the battery is fully charged, the energy generated by the alternator is sometimes too great for the power system to absorb. This may lead to briefly increased voltage, and the lights mentioned above may briefly flicker. This characteristic is caused by the alternator design and is a normal condition of the vehicle. |
| A901238 2032113- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. The customer may state that the outside ambient temperature display is incorrect. To achieve a smoothening effect of the displayed outside ambient temperature, the value shown does not instantaneously follow the temperature sensor measurement. The display will not change faster than 4° F (2° C) per minute. This concept applies to both falling and rising temperatures. A programming strategy is also implemented to avoid incorrect readings on a parked vehicle, due to the temperature sensor being affected by outside influences such as radiant heat from the engine bay, elevated road surface temperatures, etc. |
