"We reviewed vehicle data and found that service bulletin SB-
19-16-010 does not apply to this vehicle. Vehicle already had updated parts installed. The sound you are hearing is an acoustic characteristic of the product resulting from a sheet metal cover adjusting due to thermal expansion or changes in ambient pressure. There is no impact on functionality; you can continue to drive and Supercharge your car as you wish. At this time we will cancel the appointment if you do not have any more concern. Thank you for your time."
