| A941559 2039584- | 2017-10-21. Service bulletin. ELECTRICAL SYSTEM. A bulb failure warning for one or several taillight functions appears in the instrument cluster, but the taillights are operating normally. The warning only occurs at very low outside temperatures. DTC entries are logged in the comfort system central control module. The transistor in the taillight is a component of the bulb failure monitor. The transistor is out of tolerance, which causes the bulb failure monitor to not see enough current consumption when outside temperatures are very low. This causes a false lamp failure warning. |
| A371554 2030582- | 2017-10-21. Service bulletin. EXTERIOR LIGHTING:HAZARD FLASHING WARNING LIGHTS. Customer may report that the transmission warning light comes on.

| A961604 2042811- | 2017-10-04. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Audi connect Gen1 and Gen2 systems: Differences and troubleshooting. The customer has a general concern related to Audi connect. Different features are included with different generations of the Audi connect system. The Audi connect Gen1 system includes all vehicles that utilize a removable plastic SIM card. The Audi connect Gen2 system includes all vehicles that utilize an embedded SIM card. The root cause of all complaints cannot be attributed to the vehicle hardware because of the backend server configurations that need to be correct in order for Audi connect to work. For most sporadic complaints, the issue typically resides with the MBB backend server or with the source data provider (Google, INRIX, etc.), and not with the vehicle. In rare cases, the mobile network operator (AT&T, T-Mobile) can be the cause of the complaint. For most static complaints, the issue can be attributed to the user account subscription or possibly the vehicle hardware. |
