I'm guessing that you meant a P0297 code, which, after some quick googling is defined as:

Indicates the vehicle has been operated in a manner which caused the vehicle speed to exceed a calibration limit. The vehicle speed is continuously monitored and evaluated by the Power Train Control Module (PCM. The DTC is set when the vehicle speed exceed the calibrated limit set within the PCM.)

Been on the Autobahn lately? :D

I found a Vag code 00297 (IF that's what you meant), which tranlates to 3 P-codes:

00297 P0715 Input/Turbine Speed Sensor Circuit - Malfunction
00297 P0721 Vehicle Speed Sensor Circuit - Range/Performance - Signal
Noisy (G38)
00297 P0722 Vehicle Speed Sensor Circuit - No Signal
00297 Transmission Vehicle Speed Sensor (G38)
