Whoa that is loud. Does it only happen during cold morning start for u? Or does it happen every time u drove it consistently?? I heard this twice but never on a cold start. Happened like after I washed the car the last two times but after driving for a good 30 mins or so and only when I was stopped at the light.
Pls keep us posted when u get the car back.
