ok, i got my xf last sunday, had a surgery on my left hand on Tue. didnt quite enjoy driving it 
anyway, theres something that bothers me..everytime i start the car, especially if i leave it off for few hours. This happens everyday on my way to work, when i start the car, warm it for 10 mints. Reverse, then shift to D, once the gear shifts from 1 to 2, a "Click/knock/Crack sound" comes from the engine/AC/Hood not sure. That happens only once. So if i stop the car, turn it off/on, it wont happen again. unless i leave the car off for like few hours, then it wud haPPEN AGAIN. any reason 4 this
?? is it normal?
i dont feel like putting the car in the workshop when its still new. *am typing in 1 hand only*
once am ok, ill take pics as promised
