No choice, SE price up, but plastic part still the cheapskate as BLM/FL, plus your absorber is hard...
Since i got my car until now almost 2.5 years, i nv stop to fix those rattling issue by myself,
i only can say, improve alot compare to stock, almost no rattling sound except extremely uneven road.
Just can give you some hints if you want to DIY solve it.
For dashboard, use sponge and insufflex...not to paste on it, is to find out by part by part knocking, then force insert those material into the narrow empty space...
Also the center console, if you press with your finger, you will hear 'nyek nyek' contact noise, this is due to direct contact between two different plastic, this one have to dismantle and stick the clear tape on the edge to isolate the edge from directly contacting.
For door, deadening is the only effective way to solve it.
This weekend if i got time i will post some snap shot the location i insert those insufflex/sponge into the dashboard.
to add.... at passenger door C pillar, the triangle black plastic.
