| 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. |
| A461630 2042646- | 2017-10-04. Service bulletin. SERVICE BRAKES. Customer may complain about brake squeak or squeal with light moderate pedal pressure. The noise is created by the brake pad material. A new brake pad (part number 4G0698151K) with improved compound has been developed. The supplier cannot currently produce this part in high volume due to factory capacity, which is causing a delay in part availability. It is possible that installing the original brake pad (part number 4G0698151D) will reduce the noise, but doing so is not always effective. |
