Enabling AudiDriveSelect (a.k.a. Charisma, Drive modes) in Audi Q3 (8U) with 2.0TDI 103kW engine.

ADS is short for Audi Drive Select. It allows the driver to choose from different driving modes: comfort, normal, auto, dynamic, efficiency, individual. Depending on installed options, there are settings for engine, gearbox, suspension, exhaust, cornering lights.

• Parameterization required. Can be done with VCP or ODIS.
• Module0x19, address0x1200, upload dataset:
  • datasets/19-gateway/0x1200_ADS-withoutEfficiency - with ADS (comfort, auto, dynamic)
  • datasets/19-gateway/0x1200_ADS-withEfficiency - with ADS (comfort, auto, dynamic, efficiency)
  • datasets/19-gateway/0x1200_noADS - no AudiDriveSelect

• Module0x55, Long Coding, Byte06, Bit7 (Charisma), enable.

• Parameterization required. Can be done with VCP, ODIS, OBDeleven.
• Module0x5F, address0xF00610, upload dataset:
  • datasets/5f-rmc2/0xF00610_CarMenu-withADS - with AudiDriveSelect menu
  • datasets/5f-rmc2/0xF00610_CarMenu-withoutADS - without AudiDriveSelect menu
• Check this for more details:https://github.com/mrfixpl/audi-rmc-coding-adaptation-datasets
• Parameterization with OBDeleven:https://www.youtube.com/watch?v=jsi80Yr3aoY

• Green Engineering Menu access required - need to enable developer mode first
  • Module0x5F, adaptation, channel6, new value1.
  • Reboot unit with button combination:[BACK] +[Control Wheel] +[Upper-Right]
  • Reboot demo:https://youtu.be/KxOsZpEe3cY
• Enable ADS/Charisma
  • Enter GEM with button combination:[CAR] +[MENU]
  • Go tocar/cardevicelist/carisma and enable it.
  • Go tocar/carmenuoperation/carisma and set it to5.
  • Reboot unit with button combination:[BACK] +[Control Wheel] +[Upper-Right]

TODOOO

ADS button can be found on wiring diagrams as elementE735. It shares theT10f 10-pin connector with Engine Auto Start/Stop button and Park Assist Button.

3 pins are related to the ADS button:

• T10f/1 - GND (ground)
• T10f/5 - Term58 (button backlight)
• T10f/9 - SIG (button pressed short to ground)

Most likely you will need to wire only the SIG line, from the button (E735; T10f/9) to the BCM module (J519; T52c/37).

• Last 4 bytes in gateway dataset is CRC-32 checksum,
• Last 2 bytes in RMC dataset is CRC-16/CCITT-FALSE checksum,
• Modes in order:Individual,Comfort,Auto,Dynamic,Offroad,Efficiency,Race.
• Looking at the gateway dataset, it seams that it supports all 7 modes, butOffroad andRace are not enabled. Might be possible to alter the dataset to get mode modes.
• Individual settings in order: engine/transmission, suspension, steering, 4x4, exhaust, belt tensioner, ACC. Additionally: contour seats, cornering lights.
