seems to have developed a rattle which is either coming from the right hand side of steering wheel on dash or the drivers door panel.

difficult to locate it when driving - any ideas where to look first?

 

exhaust heat shield

 

when road surface completely smooth - no rattle. Definately coming from inside the car towards drivers side front. By the way its on a 2003 STi.

 

As above loose heatshield, turbo/downpipe.Or someone has dropped coins down the door when the window was down...

 

The classic rattle My car is full of them. I will sort them all out one day

 

Try the trim panel along the base of the windscreen. Mine rattles like a good'un unless I wedge it with foam, or silicone.

 

the sound travels through the heating ducts, it did on mine anyway and it was the heat shield, also sounded like it was definatly in the car. took mine to scoobyclinic in the end and they sorted in a minute and laughed at me for longer lol.
