Well, not quite as bad as that. Some days quiet, can’t get a rattle if you tried. Today, after driving with the sun beating down on the plastic, rattles like crazy. Was hoping to keep the car off lease due to the current market but now don’t know. Appreciate advice. Thanks.

Not me but I have the leather dash.

No luck taking it to the dealership?

Not a squeak. However I had a rattle in my old E60 after I bought it. It annoyed the shit out of me when idling at stop lights. I scheduled a service appointment— they could hear it too (so no issue making the case). I had a loaner for two days while they figured it out. They said they took the whole dash apart and tightened things down. All I know is they fixed it under warranty. I was impressed. Give that a shot unless you're out of warranty.

Hi, I’m the OP. Took car to Freehold BMW last week and rode with a most patient service Mgr. But dash was simply not rattling. Nothing could be done. Very weird how it’s dependent on a mix of outside temperature and sunshine! I’d love to get inside there myself but I know I’d probably make things worse!

It's always the way, issue present all of the time except when there is a technician in the car

It's really not all that weird. Sun beating down on your dash will cause that giant piece to move/swell in all sorts of ways that changes its relationship to the other parts it is rubbing against/connected to. You need to go back to the dealer when the conditions are present.

Or take a passenger along for a ride to grab video with sound. Can be really valuable if the conditions are hard to align with getting a tech into the car.
