Affected Component: POWER TRAIN:AUTOMATIC TRANSMISSION

Summary
"THE UNWARRANTED ERROR MESSAGE ""GEARBOX FAULT"" CAN APPEAR SPORADICALLY IN THE INSTRUMENT CLUSTER ON THE AFFECTED VEHICLES BECAUSE THE DIAGNOSTIC FUNCTION FOR THE HYDRAULIC VALVES IN THE PDK TRANSMISSION IS TOO SENSITIVE. IF THIS HAPPENS, THE PDK TRANSMISSION SWITCHES TO THE REDUCED DRIVING PROGRAMMED AND THE CHECK ENGINE LIGHT IN THE INSTRUMENT CLUSTER WILL BE ACTIVATED. RE-PROGRAM THE PDK CONTROL UNIT USING THE PIWIS TESTER WITH TEST SOFTWARE VERSION 16.400.010 (OR HIGHER) INSTALLED."
