Hey all, just created an account hoping for a little insight into an unusual noise I've noticed on my recently purchased TL.
The sound is coming from this small little box: http://imgur.com/a/gr5XN
- One line coming from the box goes directly to the throttle body, and the other down the firewall and under the car
- From inside the cabin and with the hood open, the sound is like a rapid, rhythmic, ticking sound. With a stethoscope on the box, it sounds like a small bell dinging.
- It is very quiet at idle, but the volume and frequency both increase with any manipulation of the throttle.
What I'm wondering is what the box is, what might be wrong with it, and how I can fix it. Any insight is greatly appreciated.
