Control unit code
The code for both the standard and the sporty running gear is 15500.
System initialisation
The system initialisation process includes cal-
ibration of the vehicle level senders.
This is required whenever a sender or the
control unit is replaced.
System initialisation is performed using diag-
nostic tester VAS 5051(address word: 34 –
adaptive air suspension).
The height of each wheel is measured from
the centre of the wheel to the lower edge of
the wheel housing.
The measured values are transmitted one
after the other to the control unit by means of
function 10, "Adaptation". The specified
dimensions are stored in the control unit. The
correction factors can be determined by com-
paring the specified values with the meas-
ured values.
