46 Rattling noises at 25 mph after pulling away 46 17 73 2047919/1 June 29, 2017. Model(s) Year VIN Range Vehicle-Specific Equipment A4, A4 allroad, S4, Q7 2017 - 2018 All Not Applicable A5, A5 cabriolet, A5 Sportback, S5, Q5 2018 All Not Applicable Condition After pulling away, a slight rattling or clicking noise maybe heard from the front of the vehicle at about 25 mph. It might be felt also slightly through the accelerator and brake pedal. Technical Background The ABS/ESP system performs a short self-check during which all valves of the hydraulic unit are operated at the same time and the return pump runs briefly. This functionality ensures the pre-load of the ABS pump and the readiness of the Pre-Sense System if required. The self-check is necessary for a correct operation of the ABS/ESP system. The resulting noises are unavoidable. Individually the volume of this self-check can be perceived differently. This depends on various factors such as the general noise level in the vehicle, driving conditions, and etc. Therefore, the volume of this self-check may be perceived differently from vehicle to vehicle. Production Solution Not applicable. Service The replacement of the ABS/ESP does not improve the situation and is not permitted. Page 1 of 2 © 2017 Audi of America, Inc. All rights reserved.
