I have a 05 TL that runs just fine and I haven't had any problems with it but, there is like a howling noise between 30 and 40 mph when I am just barely touching the gas. It is sometimes worse depending on how cold it is outside. Do any of you guys know what could be making this noise or have you experienced it before?

Sounds like the heat shield issue. See the last page.
