Service bulletins for the 2013 Audi A4
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| Edition114 | 2023-02-06. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. Wastegate linkage dissconnected |
|---|---|
| Edition83 | 2023-02-06. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM:IGNITION. 97 no start |
| 01140320332233 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. The programmed values for the misfiring recognition are not automatically reset by deleting the memory once. |
| 01137320332231 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Engine warning light on after engine replacement |
| 01137220332111 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING; FUEL/PROPULSION SYSTEM. Technical Background: Under extreme driving conditions (e.g. long idle periods or extended stop and go traffic), high temperatures build up in the rail system and can lead to steam bubbles in the fuel. This causes temporary drops in fuel pressure, causing DTC P008700 (fuel rail pressure too low) to be stored. Freeze frame data will indicate those extreme driving conditions: coolant temperature is above 102? C. Production Solution: Software to optimize the cooling strategy to solve this issue is currently in development. |
| 01133920353482 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; FUEL SYSTEM, GASOLINE. Under extreme driving conditions with the A/C compressor switched off (e.g., long idle periods or extended stop-and-go traffic), high temperatures can build up in the fuel rail and may lead to fluctuations in fuel pressure, possibly causing DTC P008700 to be stored. Coolant temperature above 102?C in the freeze frame data can be an indicator of those extreme driving conditions. |
| 01132920332232 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). The programmed values for the misfiring recognition are not automatically reset by deleting the memory once. |
| 00146620379491 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). A DTC with the description ?Invalid Data Record? is stored after an ECU has been replaced or updated. |
| 00146320335762 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. 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. |
| 00145920297372 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. When oil is drained through the drain plug, the oil might spill on components around the oil pan area. If it is not properly cleaned up, this spilled oil could drip after the procedure is complete, causing unnecessary customer complaints. |
| 00134920335761 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. 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. |
| A1922332061604_5 | 2022-12-06. Service bulletin. EQUIPMENT; ENGINE AND ENGINE COOLING. This bulletin contains instructions for resolving a coolant leak. |
| 20144320350737 | 2022-10-31. Service bulletin. ENGINE AND ENGINE COOLING. System Leak Detected. |
| 01140320332233 | 2022-10-31. Service bulletin. ENGINE AND ENGINE COOLING. The programmed values for the misfiring recognition are not automatically reset by deleting the memory once. |
| 01138220332114 | 2022-10-31. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING.

| 01138120332113 | 2022-10-31. Service bulletin. STRUCTURE; ENGINE AND ENGINE COOLING; SERVICE BRAKES, HYDRAULIC. Technical Background: Under extreme driving conditions (e.g. long idle periods or extended stop and go traffic), high temperatures build up in the rail system and can lead to steam bubbles in the fuel. This causes temporary drops in fuel pressure, causing DTC P008700 (fuel rail pressure too low) to be stored.

| 01146320336302 | 2022-09-26. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Because there are a number of different misfire faults (unrelated to ignition coil operation) that could cause the MIL to illuminate, proper Guided Fault Finding (GFF) misfire diagnosis must be followed before any ignition coils are replaced. |
