◆ Sporadically occurring faults (temporary faults) will be indicated on the V.A.G 1551 display as "SP". The
word "sporadic" means "intermittent" or "occurring at irregular intervals".
◆ Components that are indicated as being faulty by the V.A.G 1551/VAS 5051 should not be renewed imme‐
diately. Always start by checking the wiring, connectors and earth connections for the component using the
current flow diagram. This is particularly important in the case of sporadic faults (indicated by the letters
"SP"on the fault reader display).
