4.5 Transmission Control Module Safety
Functions
If one or more components and/or sensors malfunction, the au‐
tomatic control module will activate the appropriate replacement
function. This guarantees the non-destructive operation of the
transmission with respective implications on shift function and
quality.
When malfunctions are detected by the transmission, a distinction
is made between 4 possible statuses.
♦ 1.: The fault is stored and a substitute program permits further
driving (in some cases with restrictions). The driver is not no‐
tified of this status, because it is neither critical for the driving
safety nor for the transmission. The selector lever position in‐
dicator in the instrument cluster provides a normal display of
the current selector lever position arrow. The driver will only
notice the fault - if it is noticed at all - in terms of handling
problems and will then automatically consult Audi Service.
♦ 2. Certain selector lever positions will flash in the transmission
range display in the instrument cluster. The driver is shown
that a desired gear selection is currently not possible. This is
the case if, for example, a reverse drive (selector lever position
“R” and the vehicle rolls backwards) is engaged in the driving
gear “D”. The selector lever position “D” in the selector lever
position indicator in the instrument cluster will blink in this
case. The transmission control module prevents engaging the
1st gear in order to avoid damaging the transmission. The 1st
gear is engaged after the vehicle comes to a standstill.
♦ 3. The selector lever position display in the instrument cluster
is completely illuminated and blinks. The selector lever posi‐
tion can be recognized in the instrument cluster, for example,
“D” is highlighted. The transmission was overloaded in this
case and the maximum temperature in the transmission was
exceeded (overheating), for example, due to towing a trailer
with an excessively high load.
♦ 4. A fully illuminated, flashing transmission range display in
instrument cluster is an indication of a serious fault in the
transmission. In the display in the instrument cluster, you can
no longer recognize which position is selected on the selector
lever. The status is critical for driving safety or for the trans‐
mission. Under certain conditions, all gears can no longer be
engaged. Through the blinking gear selection indicator, the
driver is told to visit an Audi service dealer.
