Control unit for head-up display J898

The hardware of control unit for head-up display J898 is taken from the Porsche Taycan. Useful information is projected into the

driver’s field of vision in full colour. The projection is such that the information appears to be approximately 3 metres ahead of the

driver.

On the Audi e-tron GT (type F8), the networking is based on the MLBevo2 platform. This means that, as on other models that use

the platform, the head-up display on the Audi e-tron GT (type F8) communicates with the other control units in the vehicle via the

instrument cluster CAN data bus. Larger volumes of data are transmitted via the Ethernet cable, which is a single twisted-pair cop-

per cable.

The Ethernet connection is used to transmit navigation data such as the bar graph views or the detailed intersection map.

The display is divided into the main area, the status area and an area for temporary content. The content shown is specific to the

Audi e-tron GT (type F8), but there are strong similarities to the content displayed on an Audi A6 or Audi A8.

Unlike control unit in dash panel insert J285, control unit for head-up display is not a node of the component protection system. It

can be accessed via diagnostic address 0082 on the vehicle diagnostic tester.

There will not be a calibration board for adjusting the eye box in the workshop, as all the necessary adjustments (e.g. changes in

height or corrections to the angle of the image) can be made by changing the settings in an MMI menu.

other Audi models, the Audi e-tron GT only has surface lighting in the interior and does not have contour lighting. As on various

other Audi models, if this equipment is fitted, surfaces such as the doors are highlighted by LEDs. The brightness and colour of the

LEDs can be adjusted in the MMI menu.

Central locking system with convenience key

684_240

The central locking system with remote control is standard equipment on the Audi e-tron GT and works in the same way as on the

other Audi models that are based on the MLBevo2 platform. For example, the reception antenna for the remote control is also

located on the printed circuit of convenience system central control unit J393 on the Audi e-tron GT.

Vehicles with the convenience key have a fifth Kessy antenna. Front antenna for entry and start authorization R376 is fitted at the

rear of the front compartment.

This antenna was first introduced with the launch of the Audi A8 (type 4N), although it was later discontinued in that model. On

the Audi e-tron GT, this antenna is fitted on all vehicles that are equipped with the convenience key. Diagnosis of R376 is possible

with the vehicle diagnostic tester. The antenna is active for the convenience key function. Front antenna for entry and start

authorization R376 is required for the remote park assist plus, which is being introduced with the Audi e-tron GT.
