Service bulletins for the 2008 Audi TT

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.

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

1449202844022022-08-01. Service bulletin. BACK OVER PREVENTION:DISPLAY FUNCTION. The customer complains of one or more of the following issues: ? When the vehicle is completely refueled, the vehicle range (?distance to empty?) that is displayed is different than the vehicle range that was displayed the last time the vehicle was completely refueled. ? The displayed vehicle range drops inconsistently. ? After the vehicle is refueled, the displayed vehicle range does not change for a long period of time. ? When the vehicle is driven on hilly roads for a long period of time, the displayed vehicle range suddenly changes by a significant amount. ? There are no DTCs related to fuel senders stored in the instrument cluster control module, J285 (address word 17). This condition does not involve or affect the accuracy of the fuel level indicator, but only the estimated distance to empty display on the on-board computer.
1338201291352022-08-01. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:FLUID/LUBRICANT:FILTER/SCREEN. Engine oil service - filter cartridge replacement. When changing the oil filter and installing the new filter seal(s) in the oil filter housing, special attention is required.

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 13 19 20290102022-05-31. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Low battery charge: excess current draw location
A9022572032113_62022-05-05. Service bulletin. EQUIPMENT:ELECTRICAL. This is an informational bulletin containing information about the outside temperature reading.
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 09 20287152022-05-02. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:GEARS. After a mechatronics, torque converter, or complete gearbox replacement, the clutches must be adapted to the new component. This requires a gradual move of the clutch linings toward the optimal operating points in the most diverse load conditions. As a result, sporadic driving power disruptions lasting for less than a second or reduced shift comfort are possible over the first 500 miles. This is normal, and these issues will decrease over time. The issues can also occur if the adaptation values of the gearbox were deleted.
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).
