Vehicle Compatibility

This control module may be suitable for selected Audi Q7 4M vehicles equipped with the compatible factory Night Vision Assistant system.

Compatibility depends on the vehicle production date, camera specification, instrument cluster, gateway, lighting equipment, software version and factory driver-assistance configuration.

Please compare part number 4M0907547D, the connectors, hardware information, software details and all additional label numbers with the original module before purchasing.

Part number 4M0907547D replaces selected earlier 4M0907547A and 4M0907547B modules, but vehicle-specific compatibility and programming requirements should still be confirmed before installation.

Coding and Programming Requirements

Component-protection removal, coding and vehicle-specific configuration are normally required when installing this control module into a different vehicle.

The replacement J853 module may require Audi component-protection commissioning, control-module coding, parameterisation and software configuration using compatible diagnostic equipment with authorised online access.

The coding must match the vehicle's thermal camera, instrument cluster, gateway, headlight system and installed Night Vision Assistant equipment.

A used module from another vehicle should not be considered plug-and-play. A diagnostic scan and stored fault-code clearing should be completed after installation.

Calibration Requirements

Replacing or updating the J853 control module by itself does not normally require the night-vision camera to be recalibrated.

Camera calibration may be required if the thermal camera has been replaced, removed, repositioned or if its mounting position has been disturbed.

Any required calibration should be completed using the correct Audi diagnostic procedure and suitable calibration equipment.

Retrofit Information

Retrofitting Night Vision Assistant into a vehicle that was not originally equipped with the system requires more than this control module.

A complete retrofit may require a compatible thermal camera, camera mounting components, wiring harnesses, instrument cluster, gateway, switchgear, grille components and vehicle-specific coding.

Installation Information

Professional installation by an Audi technician or experienced automotive driver-assistance specialist is strongly recommended.

The vehicle should be diagnostically tested before replacing the module to confirm that J853 is responsible for the fault. The camera, wiring, connectors, power supply and vehicle communication network should also be inspected.

After installation and commissioning, the night-vision image, warning functions, pedestrian and animal highlighting, instrument-cluster display and communication with related vehicle systems should be tested where equipped.
