Service
Ask the customer the following questions and note them in the claim comments:
• When did the Audi pre sense front intervention take place? [day, month and year]
• Was the red Audi pre sense symbol displayed in the instrument cluster during the complaint? [yes/no]
• Was a warning tone issued at the same time that the red Audi pre sense symbol was displayed? [yes/no]
• Were the hazard warning lights switched on or the side windows closed at the same time? [yes/no]
Perform the Audi pre sense test program. The test program can be found under:
Test plan > Select self-test > Body > Electrical system > 01 - On Board Diagnostic capable systems > 0013 Control Module for Adaptive Cruise Control -J428- > 0013 - Technical Service Bulletin (TSB) > Audi pre sense
The test program asks you to enter the date of the customer complaint.
The test program checks whether Audi pre sense front interventions took place in the period between three days
before and three days after the date entered.
At the end the program provides a list of the Audi pre sense front interventions during this period.
• Audi pre sense warning
If the vehicle approaches a vehicle travelling 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.
• Audi pre sense 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.
• Driver-triggered emergency 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.
• Automatic partial braking (preliminary stage)
If the driver does not respond to the warnings, an urgent warning is issued in the form of 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.
• Automatic partial braking (main stage)
Emergency braking is triggered. In situations where a collision cannot be avoided, additional support is provided
to the driver in the form of automatic braking to bring the vehicle to a standstill. In this case, the front assist
applies the maximum braking force.
• Swerve support
The swerve assist is active at speeds above 19mph. If a collision warning is required, the system performs a
brake jolt as a warning. The system supports the driver by providing a small amount of steering torque (max.
2 Nm) to correct the steering angle/assist with changing lane. The systems used for the swerve assist are: front
assist, ACC and lane assist.
• Brake dead time minimization
If a hazardous situation is identified, the hydraulic brake system is pre-charged and a slight jolt is noticeable.
• Turn-off function (turn assist)
Emergency braking may be initiated during a left turn at speeds of up to 9mph. The function can prevent a frontal
collision with an oncoming vehicle when turning off.
Please note that only the last four events in each category are stored.
The Audi pre sense test program must only be performed once per complaint. As an exception to this, if the
customer specifies several times when the complaint occurred, the Audi pre sense test program may be
performed a maximum of three times for the complaint.
