Over the last couple of months, my car has developed a clicking or tapping sound under the dash. It started off only happening driving home from work but now it is all of the time. A/C on or off. Hot or cold. It does it all the time. Sounds like it is coming from under the steering wheel and it is an irregular timed tap/click. Just one tap at a time. Has anyone else experienced/heard this? I guy on VW Vortex was told by his dealer that it was a gas leak detection pump doing it's thing which I find bizarre. Just had some warranty work done 2 weeks ago so don't want to go back yet.
