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.

011463203363022023-01-03. 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.

011382203321142023-01-03. Service bulletin. ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC 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.
