With Mode 3, DTC memory is checked-with Mode 4, DTC memory is erased.

Mode 5 shows the statistical value of the oxygen sensors as mandated by law. As these values have no direct bearing on
oxygen sensor diagnosis, Mode 5 is of no particular value in an Audi Service department.
Under Mode 6, values can be checked for components and systems that are not continuously monitored.
With Mode 7 all malfunctions can be checked, even if they have not switched on the Malfunction Indicator Lamp (MIL) (if
the MIL has not been switched on, there is no malfunction recognized under Mode 3)

abrupt load changes, etc.
Increased fuel consumption
Elevated exhaust gas values
Reduction in transmission service life
Malfunctions not present are stored in DTC
memory
Necessary functions are not carried out (oxygen
sensor control, actuation of EVAP canister
