Flexible service interval indicator
The service interval indicator informs the
driver when a service is due.
If the remaining distance until the next service
is less than 2,000 km or if a year has elapsed, a
message appears on the combi-display every
time the ignition is turned on. The driver can
call up the remaining distance until the next
service on the display at any time by pressing
the check key.
Service
The fixed interval indicator, i.e. limitation of
service interval to 15,000 km or 1 year, will be
gradually replaced by a flexible service inter-
val indicator in the Audi TT Coupé. By compa-
rison with fixed maintenance intervals, the
flexible service interval indicator will enable
the performance margins of the engine oil to
be utilised to full capacity. A new type of sen-
sor for oil level and oil temperature recogni-
tion has been developed for this purpose.

Oil level sensor
The oil level sensor is installed in the oil sump
from below.
The level and temperature data are determi-
ned continuously and transferred to the dash
panel insert in the form of a pulse width
modulated output signal.
The “Adaptation” function in the dash
panel insert, the flexible service inter-
val indicator can be converted to a
fixed interval indicator.
