Memory Seat/Steering Column Adjustment Control Module J136/J521
The new Audi A8 is available with different front and rear
seat versions.

The seat ventilation system is equipped with two fans per
seat - one in the seat cushion and one in the seat back.

In the full trim version the individual contour seat has seat
heating, seat ventilation and a massage function. The seat
heating and ventilation systems can be adjusted separately
in three stages.

The fans are configured as an aspirating system. To facilitate air intake between the passenger and the seat, a
breathable seat cover (perforated leather) is required. This
air flow wicks away moisture and creates a pleasant and dry
climate at the seat contact surface.

Sunroof Control Module J245/J392
The panoramic glass sunroof has two glass panels. The
front glass panel can be lifted or opened, while the rear
glass panel is fixed.
The sliding sunroof and the front and rear roof roller blinds
can be operated from both the cockpit and the rear passenger compartment.
The panoramic glass sunroof and the front roof roller blind
can also be pushed open or closed in a single motion by
pushing or pulling Sunroof Button E325 to the second
position twice in short succession.

Unlike the panoramic glass sunroof of the previous model,
the rear sunroof segment cannot be tilted. Rear Sunroof
Control Module J392 no longer incorporates Rear Sunroof
Motor V146. Tasks of Rear Sunroof Control Module J392
include controlling the rear roof roller blind.
The front glass sunroof segment can also be operated from
the rear passenger compartment. Depending on trim level,
the sunroof can be operated either with the buttons in the
rear doors or, alternatively, with the optional Rear Seat
Remote System.

Power Adjustable Steering Column Control Module J866
The steering column of the 2019 A8 is adjusted electrically.
The control module has a Terminal 30 power supply to
ensure the column can be positioned even when the ignition is switched off.
In models with a memory function the steering wheel
position is stored in a key-specific manner together with
the seat position.

Power Adjustable Steering Column Control Module J866
implements the driver commands, which are transmitted
via Steering Column Adjustment Switch E167. J866 participates in bus communication within the vehicle as a LIN bus
user of Vehicle Electrical System Control Module J519.
The electrically adjustable steering column control module
is located directly at the steering column. It can be
accessed using Address Word 09 with the VAS Scan Tool.

An easy entry function makes it easier to enter and exit the
vehicle by moving the steering column up into a park position after the ignition is switched off.
