This was much louder than a 'tap' or It almost sounded like an exhaust pipe banging against the frame, but it was coming from the engine compartment.

It would come and go as the idle went up and down. But it was there most of the time.

Dreadful sound... hope no one else experiences it.

2 months of feeling totally secure and not finding any unexpected mechanical flaws with this vehicle, then I get a flat last week and now this.
