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.

662 on file from NHTSA, as of 2026-10-19.

001353203550512022-09-26. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Audi on Demand Special Vehicle Repair Authorization
011463203363022022-09-26. 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.
011403203322332022-09-26. Service bulletin. ENGINE AND ENGINE COOLING. The programmed values for the misfiring recognition are not automatically reset by deleting the memory once.
011386203363012022-09-26. Service bulletin. 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.
011382203321142022-09-26. Service bulletin. FUEL SYSTEM, GASOLINE. 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.

011339203534822022-09-26. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. 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.
011331203534812022-09-26. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Under extreme driving conditions with the A/C compressor switched off, high temperatures can build up in the fuel rail and may lead to fluctuations in fuel pressure, possibly causing DTC P008700 to be stored.
011329203322322022-09-26. Service bulletin. ENGINE AND ENGINE COOLING. The programmed values for the misfiring recognition are not automatically reset by deleting the memory once.
011309201475382022-09-26. Service bulletin. FUEL SYSTEM, GASOLINE. The use of contaminated gasoline or gasoline with a low content of deposit control additives may result in one or more conditions.
001470203920612022-09-26. Service bulletin. EQUIPMENT:ELECTRICAL. High quality media files (video and sound) are now integrated into technical service bulletins on a case-by-case basis. Media files can now be viewed on any smartphone or tablet.
001466203794912022-09-26. Service bulletin. EQUIPMENT:ELECTRICAL. A DTC with the description ?Invalid Data Record? is stored after an ECU has been replaced or updated.
0014652011732102022-09-26. Service bulletin. EQUIPMENT:ELECTRICAL. This Technical Service Bulletin (TSB) details the general process for carrying out a Software Version Management (SVM) software update for any TSB or Update.
001463203357622022-09-26. 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.
001459202973722022-09-26. 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.
001349203357612022-09-26. 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.
