Hi,
Is that normal sound of N54, when its cold? It's totally gone after 2-3minutes.
Sounds like this, at the morning.
stops, goes silent when I add a little gas. Back when idle decrease.
it's not depend on rpm

UP.
Today, I recorded a video with that ticking noise.
And: Its like some electrical device. I can hear It only at driver side, not from the engine - from under the air filter. It stops when I press the gas pedal and returns when idle. Stops after few minutes, and comming back next morning.

It sounds like an injector. But to be sure, can you get a video of it while blipping the throttle just a bit? It might be wastegate rattle, but it's hard to tell with just a straight idle video. If it's an injector there's a video on youtube of a guy showing you how to diagnose which injector it is. You'd need to replace the injector and have it coded in, or just have the dealer replace it.

In my opinion it is tank ventilation valve. Cause I've got an 2A16 error code: tank ventilation micro leak and It cause SES.
At the monday I'll replace that valve.
As U can see, near by engine is silent. When I take camera close to air filter, where is that valve, there is louder.
If I take a little throttle, stop ticking until 600rpm idle.
I'm talking about #2 video, because is mine.

The ticking in the second video is 100% the Evap purge solenoid.

'Evap purge solenoid' is the same as fuel ventilation valve?

Is that normal working of this device or not?

Yea it's #1 in that picture. I don't think the ticking affects the functionality of the valve. Mine was making the same noise and there were no codes but I replaced it anyways since the ticking really annoyed me.

For few last months I've got SES (Fuel vent tank micro leak). I think, that It'll be cause of my SES - wrong work of that valve.

Perfectly normal. If it goes silent after a throttle blip - it's functioning normal.

My dealer said, that I have to replace Ventilation Tank Valve - Is that true?
Because If U said its normal... Am I really have to do this?
It is possible, to that valve cause error code: fuel ventilation tank micro leak and SES?

If you have a Check Engine Light, then I'd replace it.

IDK what it's called but the ticking noise that goes away after a throttle blip is a normal characteristic of this car. If you have a CEL then there still may be something else wrong. Sorry to be so broad but this car is so gray at times with its quirks.

It's stops ticking, when I just a touch gas pedal. And everytime, when is ticking, stops for a few minutes. After 2-3min engine is silent.

I had the same thing for years and finally resolved it - I used Liqui Moly 5w-30 and no more tick, oil starvation is causing this, I dont know what everyone else above is talking about

I have a thread about it, another guy attested to this also -

our local Napa store has Liqui Moly oils & they dont give me a share for advertising
