Service bulletins for the 2004 Audi A8

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.

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

1310201828842022-08-01. Service bulletin. BACK OVER PREVENTION. If the vehicle?s engine experienced a serious mechanical problem, it is possible that small pieces of metal debris resulting from the mechanical problem may have become deposited in the intake manifold, air intake hoses, exhaust manifolds, exhaust down-pipes, turbocharger, supercharger, and/or intercooler. If these pieces are not removed prior to the installation and operation of the replacement engine, the pieces may be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine damage.

37 13 07 20336582022-05-31. Service bulletin. POWER TRAIN. Vehicle lacks power or will not move after stop due to simultaneous depressing of the brake and accelerator pedals
27 14 24 20253602022-05-31. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Low battery charge: Diagnosis tips and TAC instructions
37 14 31 20130022022-05-02. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION:FLUID/LUBRICANT:SEALS/GASKETS. As the sump pan gasket settles, the torque of the bolts decreases and the seal may leak. Automatic transmission fluid is leaking at the sump pan gasket.
37 14 30 20036582022-05-02. Service bulletin. ELECTRONIC STABILITY CONTROL (ESC):CONTROL MODULE:SOFTWARE; POWER TRAIN. This condition may be caused when the brake pedal and the accelerator pedal are depressed simultaneously. Drivers who drive with their left foot resting on the brake pedal are prone to experience this condition. With the introduction of Electronic Power Control (EPC) (no accelerator cable) to fuel injection systems, an engine RPM control feature has been incorporated into the engine electronic control system software. Customer states that the engine returns to idle speed of approximately 1,400 RPM although the accelerator is depressed, and/or the vehicle hesitates (lacks power on take-off).
37 13 07 20336582022-05-02. Service bulletin. SERVICE BRAKES. This condition may be caused when the brake pedal and the accelerator pedal are depressed simultaneously. Drivers who consciously or unconsciously drive with their left foot resting on the brake pedal are prone to experience this condition. With the introduction of Electronic Power Control (EPC) (no accelerator cable) to fuel injection systems, an engine RPM control feature has been incorporated into the engine electronic control system software. As a result, application of the brake and accelerator pedals at the same time (brake pedal with left foot and accelerator pedal with right foot) results in the following: ? Brake pedal function (normal at all times) overrides any throttle application. ? Diagnostic Trouble Codes (DTCs) will not be stored. ? When the brake pedal is applied while the accelerator is depressed, engine RPMs will return to idle speeds of 1400 RPMs after approximately two seconds. ? When the accelerator is applied while the brake pedal is depressed, the vehicle accelerates slower than usual (reduced engine torque).
