The Digifant injection system control unit can recognize and memorize some of the faults that occur during engine operation. Recognized faults are recorded in the drive's memory. When an Audi vehicle is taken to a workshop for inspection, the fault memory is read using a special tool. It is not possible to read fault memory data at home. If you suspect a fault in the ignition/injection control, only the r Audi workshop can interrogate the memory of the fault memory. Additionally, you can use our list of faults, in which we have listed a large number of possible failures that are beyond the scope of self-diagnosis. After troubleshooting, the memory of the fault memory is erased by the reader.
