New identity
As is already the case with the Audi A8 ‘03 , if a
control unit is stolen, it is no longer necessary
(for safety reasons) to also replace the remaining
control units, which are integrated in the
immobiliser.
In this case, the "New Identity" function must be
used for the control unit for access and start
authorisation and the engine control unit.
It is only a matter of installing a new lock set before
using the "New Identity" function.
The switch for access and start authorisation E415
reads in the key code in electronic form only.
The hinged bit coding is not evaluated signal.
The ignition switch is not par t of the lock set for this
reason.
Component protection
As is already the case with the Audi A8 ’03, the
Convenience and Infotainment control units are also
integrated within the "Component protection" safety
system.
As a result, these control units must be adapted to
the specific vehicle once they have been installed.
The data bus diagnosis interface is integrated into
the "Component protection" function for the first
time. Since component protection works via a
number of control units, the Startup menu in
"Guided fault-finding" is not assigned to any one
control unit and can be found directly under the
self-diagnosis systems.

The control units for seat adjustment can be used to
set up to 8 individual seat positions for an
electrically adjustable seat. The seat positions can
be stored in memory and can be set again if
necessary using the memory keypad or by entering
a radio code.
Installation position
The control units for seat adjustment are located in
the floor area under the driver’s and passenger’s
seat.
The control unit can be used both for the driver’s
seat and for the passenger’s seat by assigning
a PIN code in the connecting plug.
The unlearned/uncoded control unit is thus coded
automatically for either the driver’s seat or
passenger’s seat installation position – depending
on the pin – when it is first connected to the seat.
This operation can only be performed once, but can
be released again by means of the diagnostic
function (in the Conditioning menu item).
Diagnosis
The following diagnostic functions are available
under the address words 36 Seat adjustment,
driver’s side and 06 Seat adjustment, passenger’s
side:
– Read measured-value blocks
–Coding
–Actuator test
–Adaptation

Function
The control unit for seat adjustment powers the
positioning motors in the seat directly using its load
outputs. The position detection function of the
positioning motors is implemented using hall
sensors. The driver’s-side door control unit reads in
switch information from the operator unit for
memory, driver’s seat E97 as voltage-coded
information and sends this via CAN Convenience to
the control unit for seat adjustment with
steering-column adjustment memory J136.
The control unit for seat adjustment with
steering-column adjustment memory reads in
information from the switch for fore-and-aft and
height adjustment, driver’s seat E61, the switch for
backrest adjustment, driver’s seat E96 and the
switch for tilt adjustment, driver’s seat E222 directly.
The driver’s-side door control unit J386 reads in the
button information "Seat memory emergency-Off"
and supplies this discretely as well as in the form of
a CAN Convenience message to the control unit for
seat adjustment with steering-column adjustment
memory J136. Comfort functions, such as seat
symmetry positioning and comfort side view as well
as radio code allocation to a memory location, are
implemented using settings in the Multimedia
Interface (MMI).
