Fault table   Note t  All possible faults which can be recognised by the automatic gearbox control unit -J217- when the fault memory is read and displayed on the fault reader -V.A.G 1551- when the printer is switched on are listed below grouped according to the fault code number. t  If faults occur only occasionally or if the fault memory was not cleared after the faults were rectified, these faults will be displayed as “sporadic faults” for a stipulated period of time. Gearbox control unit fault detection, → Chapter. t  If components are indicated as being defective when the fault memory is read, also test the wiring to the components for short circuit and open circuit according to → Current flow diagrams, Electrical fault finding and Fitting locations. t  The fault code will be printed out in the “rapid data transfer” mode only when the printer of the fault reader -V.A.G 1551- is switched on. Example: Fault code (5 digits) 65535
