Audi Q3 (8U) AudiDriveSelect (ADS) activation

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

What is ADS?

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.

Tools required

Procedure

0x19 - Gateway

• Parameterization required. Can be done with VCP or ODIS.
• Module 0x19, address 0x1200, 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

0x55 - Headlight range

• Module 0x55, Long Coding, Byte 06, Bit 7 (Charisma), enable.

0x5F - Infotainment

Audi RMC2

• Parameterization required. Can be done with VCP, ODIS, OBDeleven.
• Module 0x5F, address 0xF00610, 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

Audi RMC4

• Parameterization required. Can be done with VCP, ODIS, OBDeleven.
• Module 0x5F, address 0xF00710, upload dataset:
  • datasets/5f-rmc4/0xF00710_CarMenu-withADS - with AudiDriveSelect menu
  • datasets/5f-rmc4/0xF00710_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

Audi MMI 3G+ (HN+)

• Green Engineering Menu access required - need to enable developer mode first
  • Module 0x5F, adaptation, channel 6, new value 1.
  • 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 to car/cardevicelist/carisma and enable it.
  • Go to car/carmenuoperation/carisma and set it to 5.
  • Reboot unit with button combination: [BACK] + [Control Wheel] + [Upper-Right]

Research

• 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, but Offroad and Race 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.
