Clicking sound at low idle
Everytime I bring to the dealer, I mention this, and they say it's normal after the engine heats up. They replaced the purge value I think it's called a whi le back, and you can still here this tapping/clicking at idle. I'm assuming this is normal?

Any chance can you film it ? At least some experts could give you a shot

Yes I do,its been there since I own car.
Apparently(according to the experts I have consulted) nothing to worry about.
There is a fix however:
