anybody else with a a3 2.0t have clicking sound in the engine compartment when idling? it sounds kinda like a metal piece vibrating.

 

Sounds like the infamous fuel line rattle. Mine emits from the passengers side of the center console. Only when cold,at idle, and not every time. There are a couple fixes around, diy-spray foam in the area, and I have heard of dealer fixing the issue. I've got an 06 and I figure this is an issue I can live with[8D]

 

My dealer says there is a TSB for this and has ordered parts from Audi (rubber grommets) to fix it.
