IS250 new owner - Dash rattle?

[nolizma]

Hi all,

I got my IS250 SE-L about a month ago and very pleased with it! Ive been driving around in that time with no issues what so ever and no sign of any rattle. 

This morning I started the car from cold and after a couple of minutes in idle I set off. Immediately a very violent sound started that caught me by surprise. It was quite alarming, to the point I stopped to check the engine as I thought it was coming from there. 

I did a lot of research before I bought the car and read a lot about the common dash rattles and was happy my car didnt suffer from it but it seems I was wrong. I blame it to the cold weather today for revealing the rattle, although it was not that extreme.

It surprised me that until today there was no rattles at all and suddenly very loud rattle. Is this the usual? I am pretty sure it comes from the dash although it sounds like coming from lower down. Behind the screen for example or even lower. But when i warmed the car up and used the windshield heater it became much better, and also pushing the dash made a difference to the sound (sometimes). Anyone had the same issue and any ideas how to stop it?
