Technical Service Bulletin
The customer experienced no Audi
pre sense intervention.

The customer did not see the Audi
pre sense symbol in the instrument
cluster.

Continue your analysis. This TSB
does not apply.

Audi pre sense basic event

The customer saw the Audi pre
sense symbol, but a warning tone
did not sound at the same time.

Explain the operation and system
limits of Audi pre sense basic to the
customer.
Use the owner's literature and the
self-study program.
Continue your analysis. This TSB
does not apply.

Audi pre sense rear event

The radar sensors of the lane
change assist permanently monitor
the traffic behind the vehicle, even if
Audi side assist is not activated.
Control units J769 and J770
evaluate the received signals,
process them and thus detect the
distance of the vehicles behind
within the detection range.

Explain to the customer the
operation and system limits of Audi
pre sense rear.
Use the owner's literature and the
self-study program.

Continue your analysis. This TSB
does not apply.
If one of the lane change assist
control units detects a critical pre
sense rear situation, lane change
assist control unit J769 sends
various information to the data bus
diagnostic interface J533 (gateway).
The definition of a critical situation is
that there could be a rear impact
from the vehicle behind if the driver
of the vehicle behind were not to
take any further action.
The data bus diagnostic interface
J533 transmits these signals to the
airbag control unit J234. On the
basis of the available information,
the J234 decides which actuators
are activated and sends this
information to different control units.

Technical Service Bulletin
Audi pre sense front warning

If the vehicle approaches a vehicle
traveling in front or a stationary
vehicle in a critical situation, the
instrument cluster can provide the
driver with visual and acoustic
warnings within certain limits.

Explain the operation and system
limits of Audi pre sense front to the
customer.
Use the owner's literature and the
self-study program.
Note the Audi pre sense adjustment
options (early/medium/late/off) in the
MMI. These influence the timing of
the warning.

Audi pre sense front warning jolt

If the driver does not respond to the
warnings, the ABS control unit J104
issues an urgent warning with a jolt.
The warning jolt is a very short,
clearly noticeable application of the
brakes that does not slow down the
vehicle. It is intended to bring the
driver’s attention back to the traffic
situation and to signal that an
immediate reaction is necessary to
prevent a collision.

Explain the operation and system
limits of Audi pre sense city and
Audi pre sense front to the
customer.

Audi pre sense front partial braking

When the driver applies the brakes,
Audi pre sense front calculates
whether the driver is braking
sufficiently to prevent a collision. If
this is not the case, the necessary
braking performance is increased
according to the situation up to the
strength required to bring the
vehicle to a standstill.

Explain to the customer that he/she
operated the brakes and Audi pre
sense front provided additional
braking assistance.

Audi pre sense front emergency
braking

If the driver also fails to react to the
warning jolt or only releases the
accelerator pedal, the ABS control
unit J104 brakes the vehicle
independently. Depending on the
vehicle speed, the braking
performance can be gradually
increased up to a full deceleration
(emergency stop).

If the customer feels that the vehicle
braked for no reason and you
require technical support, please
contact the Technical Assistance
Center (TAC).

Use the owner's literature and the
self-study program.
