Multi-collision brake
Use at Audi
The multi-collision brake has been implemented:

> In the A3 since the launch of the last model (model year 2013).
> In the TT since the launch of the last model (model year 2015).

> In the A4 since the launch of the new model (model year 2016).
> In the A6 and A7 since model year 2015.
> In the AB since model year 2015.

> In the Q7 since the launch of the new model (model year 2017).
> In the RB since the launch of the new model (model year 2017).

Multi-collision brake
Procedure at the dealer
The function of the multi-collision brake is performed by the ESC. This function is
therefore only available if the ESC is working correctly.
In the event of a fault in the ESC, the multi-collision brake is also deactivated, and
the yellow airbag warning lamp is also actuated in addition to the ESC warning lamp.
The entry "B13BCF2 multi-collision brake no function" will be added to the event
memory in the airbag control unit after the ESC is switched off.
The cause of the ESC deactivation must first be resolved; otherwise, the multicollision brake cannot be activated. The cause of an ESC deactivation is not always
due to a fault on the ABS/ESC itself. The ESC can also switch off because of a
malfunction in another system (for example, the engine).
In addition, the entry "B13BCF2 multi-collision brake no function" in the event
memory must also be deleted in the airbag control unit.

Multi-collision brake
Procedure at the dealer

> In the A6, A7, AB and RB, the following applies:
> If there is only a short-term fault or deactivation of the brake electronics, the ESC
warning lamp is switched off again at the latest after the next ignition cycle.
> However, the airbag warning lamp continues to be permanently activated and can
only be deactivated by the partner by deleting the entry "B13BCF2 multicollision
brake no function" in the airbag control unit.
> The function of the multi-collision brake also remains unavailable until this entry
in the airbag control unit is deleted.

»

The reason for the deactivation of the multi-collision brake is solely a prior
deactivation of the ABS/ESC, even if only the airbag warning lamp is lit up

Multi-collision brake
Procedure at the dealer

> If the complaint has only occurred once and then does not reoccur, all entries in the
event memory of the ESC are automatically deleted after 40 ignition cycles.

> The entry "B13BCF2 multi-collision brake no function" in the airbag control unit
remains stored even after 40 ignition cycles.

> If there is a delay of several days until the event memory can be read (for example,
due to the availability of appointments at the partner), the entry in the airbag control
unit "B13BCF1 multi-collision brake no function" may be the only remaining entry
when the event memory is read. In this case, the airbag warning lamp also remains
the only lit warning lamp.

> The dealer therefore has no indication of the prior deactivation of the ESC - either
from an entry in the event memory or through a warning lamp.

Multi-collision brake
Procedure at the dealer
If the deactivation of the ESC can no longer be detected and there is no related entry
in the event memory, the partner can only perform the following measures:

> In the airbag control unit, delete the entry in the event memory "B13CF2
multicollision brake no function"

> Continue to monitor the vehicle without attempting a repair

> If the complaint reoccurs, read the event memory as soon as possible after the
event

Multi-collision brake
Procedure at the dealer
In the A3, TT, A4, Q7 and all future models, the following applies:

> If there is only a short-term fault or deactivation in the brake electronics and the
ESC function is not available again until after the next ignition cycle, then in these
models the airbag warning lamp is also no longer actuated.

> In addition to the ESC warning lamp, the airbag warning lamp is also no longer
activated after the ignition cycle and the function of the multi-collision brake is
also active again.

ASI; creating screenshots
Screenshots for ASI:

Screenshots are sometimes required for analysis purposes in the case of complaints about the
MMI. How these are created in the MMI has already been shown in earlier SoST training sessions.
Screenshots can also be created for ASI to document complaints or monitor the causes. In the
case of such a screenshot, a record is kept of what information the telephone has sent to the
vehicle. This is helpful in sporadic cases, such as a black screen or an "offset" display of the
application.
As the display of the smartphone interface occurs on the smartphone, screenshots must be
created with the telephone, and the images are also saved on the telephone. The way you create
a screenshot is different, depending on whether you are using Apple CarPlay or Android Auto.
How to create a screenshot with the relevant system is explained on the following pages.

> To create screenshots with Android Auto,
the Android Auto application on the
smartphone must be in developer mode.
Tap 7 times in the app on Android Auto
(orange circle).

> Then, under the menu options (green
circle), call up the developer menu, set a
check mark against "Save screenshot"
(green circle).

> After this, when Android Auto is activated,
a screenshot can be created with "Share
screenshot now" (blue circle), in the
developer options on the smartphone.
The screenshot will then be saved on the
smartphone.

Repair authorization for new model launches
Key points
Always check if there is a repair authorization prior to repair during a new model
launch
Typically, the repair authorization is active for 12 weeks of a new model launch
Benefits:
Early detection of key topics/complaints
Possibility to access vehicles before repair for analysis purposes
Detect the cause of the complaint
Accelerate the fault resolution process
Accelerate the implementation of service solutions
Develop a constructive measure/software (SVM)
Information sharing between Audi dealers and AoA

Repair authorization for new model launches
Key points
Note following the repair authorization process:

> Significantly delays the implementation of
service solutions "7 customer dissatisfaction.

> Can result in claim denial.
The facts:

> Each month, over 30,000 A4/A5s are built at
Audi in Ingolstadt/Neckarsulm.

> Every day, over 35,000 platform vehicles are
built within the Group (e.g. MQB = modular
transverse matrix such as A3, Golf, etc.).

> The Audi partner is the first to analyze
customer complaints, and therefore
influences solutions and their
implementations.

Intermediate steering shaft
Squeaking noises from the intermediate steering shaft
Vehicles:

> B8 & C7 - various model years.
> Always use VIN to check for TSB.
Cause:

> Intermediate steering shaft is insufficiently lubricated
in the area of the sealing boot.
Action:

> Check for proper installation of the sealing boot.
> Updated repair involves disconnecting the intermediate steering shaft from the
steering column in order to pull out the intermediate steering shaft by approx. 4 in
(10 cm), and spray with special lubricant in the area of the black plastic sleeve and
the inner bearing race.
> It is critical to follow all steps in the TSB to prevent repeat repairs.
