Technical Service Bulletin 45 Unjustified ABS/ESC intervention during curves - Q8 3.0 TFSI only 45 23 30 2068290/2 March 17, 2023. Supersedes Technical Service Bulletin Group 45 number 22-29 dated November 4, 2022, for reasons listed below. Model(s) Year VIN Range Vehicle-Specific Equipment Q8, SQ8, and RS Q8 2020 – 2023 All Not Applicable Condition REVISION HISTORY Revision Date Purpose 2 - Revised Technical Background (Added description) 1 11/04/2022 Initial publication 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. Even after software update has been performed, it is possible that noises may still be heard from the ABS pump, especially under dynamic driving situations. These are normal operating noises which occur when preparing for a possible intervention. NOTE: • This bulletin can only be applied to MY 20/21/22 vehicles equipped with 3.0 TFSI engines. • This bulletin does not apply to SQ8 and RSQ8 models. Page 1 of 3 © 2023 Audi of America, Inc.
