This guide provides a step-by-step tutorial on how to enable additional Audi Drive Select modes in a 2013 Audi A5 Sportback using VCDS (VAG-COM Diagnostic System). This process involves modifying specific settings within the car’s control module.
Accessing and Modifying Drive Select Settings with VCDS
Before starting, ensure you have a compatible VCDS interface and software. The following instructions were tested on a 2013 Audi A5 Sportback S-Line Quattro with MMI 3G Plus and chassis type 8T-AU48 (8R0).
-
Connect and Access Central Electrics: Connect the VCDS interface to your vehicle’s OBD-II port and launch the VCDS software. Select “Select Control Module” and then choose “09 – Cent. Elect.”
-
Security Access: Click on “Security Access.” Enter the recommended security access key for this module. This key may vary depending on your specific vehicle and software version.
-
Adaptation: Navigate to the “Adaptation” channel.
-
Drive Select Standard Setting: Locate the “Drive Select Standard Setting” channel. In this specific case, adaptation channel 4 was used.
-
MMI Confirmation: Go to the Audi Drive Select screen on your MMI system.
-
Read Channel Value: Within the “Drive Select Standard Setting” in VCDS, read the current value of channel 66. This represents the currently active Drive Select modes.
-
Understanding Binary Values: Each Drive Select mode corresponds to a specific bit in a byte (8 bits). The bits are arranged from right to left, each representing a decimal value that corresponds to a specific mode:
- Bit 1 (Decimal 1): Individual
- Bit 2 (Decimal 2): Comfort
- Bit 3 (Decimal 4): Auto
- Bit 4 (Decimal 8): Dynamic
- Bit 5 (Decimal 16): Offroad (Only if Bit 7 is active. Otherwise represents Race mode)
- Bit 6 (Decimal 32): Efficiency
- Bit 7 (Decimal 64): Enables switching between Offroad and Race in Bit 5.
-
Calculating the New Value: Determine the desired Drive Select modes and calculate the corresponding decimal value by summing the decimal values of the active bits. For example, to enable Efficiency, Dynamic, Auto, Comfort, and Individual, the sum would be 32 + 8 + 4 + 2 + 1 = 47. This translates to a binary value of 00101111. Note: Race and Offroad cannot be active simultaneously.
-
Input New Value: Enter the calculated decimal value into channel 66.
-
Test and Save: Test the new configuration by cycling through the available Drive Select modes on your MMI. If everything works correctly, save the changes and exit VCDS.
Conclusion
By following these steps, you can customize your Audi A5’s Drive Select system to access different driving modes tailored to your preferences. Remember to consult your vehicle’s documentation and exercise caution when modifying vehicle settings with VCDS. Improper modifications could potentially lead to unintended consequences.
