| Features of self-diagnosis |
| The direct injection and diesel pre-heating system control unit is equipped with a fault memory. |
| If faults occur in the sensors and components being monitored, they will be stored in the fault memory together with an indication of the type of fault. |
| Faults which only occur sporadically are printed with the addendum “sporadic fault”. These faults will be indicated on the display by the addendum “/SP”. The cause of sporadic faults can be due to a loose contact or an intermittent break in a cable. If the sporadic fault does not occur again within 50 engine starts, it will be erased from the fault memory. |
| If faults are detected which influence the engine running, the preheating warning lamp will flash. |
| Memorised faults can be read on -V.A.G 1551- or -V.A.G 1552- → Chapter. |
| The fault memory must be erased after the faults has been eliminated → Chapter. |
Note! | For general information about self-diagnosis, see the instruction manuals for testers -V.A.G 1551- and -V.A.G 1552-. |
