2002 Q45, Rattling on Cold mornings when in gear.

[kev1n]

its a 2002 Q45, 76j milesbasically i start her up in the garage and she idles fine, quiet and everything.

When I put her into gear and start moving I hear some rattleing coming from underneath the car could be in Drive or Reverse, doesnt matter.

Any idea what this could be? it does not happing when the car is warm or has been outside all day.

Any thoughts would be appreceiated

I had something like this on my old Q. on the cat. converter, the heat shield was loose.. It wouldnt do it as bad once it got warm because the metal expanded...

Try and get under the car as best you cna when it does and try and narrow down where it comes from.

Excellent, I will take a look. Seems logical enough b/c it goes away once warmed up
