Condition
Customer states:
• ABS/ESC intervention happens when driving around a corner at low speeds (for example highway exits).
Workshop findings:
• No DTCs are stored in the ABS/ESC control module, J104 (address word 0003).
• It may not be possible to reproduce the issue.
Technical Background
ABS/ESC regulation on the Q8 is configured for a sensitive response.
The systems may therefore intervene in certain situations with ABS pump activation (this situation does not affect
the safety of the vehicle). Noise and vibration can happen.
Vehicles with air suspension, rear steering, summer tires, and wheel size above 20 inches may be more affected by
the issue.
NOTE:
• This bulletin can only be applied to MY 20/21/22 vehicles equipped with 3.0 TFSI engines.
