Hi djturk254,Engine is off completely dealership does not know . I caught it on video but this website wont let post link my youtube is djturk254 . If anyone can help me thank you for your time
I had a 2015 SXT new car, it always did that, guessing 90% of the time, sometimes it would go on for hours.......got a 2016RT now and i never hear it on it??....both are A8'S......it always seem to come from the bottom of trany area....I figured it just was the tranny learning thing? ....it always ran great!imp:Thank you for the info and thank you for posting the video! Car runs great . It happens every time i wash my car i do it by hand only , and it does it every now and then for about 30 mins then it slows down and eventually stops.
Well it depends on an HVAC system high/low side pressure differential. Most folks prob run the compressor at some point in the washing process...and/or are standing outside of the veh long enough to notice it.The 'only when washing' makes me doubt the spring theory for sure.
