Hi Guys,

Long story short. One day, I decided to wait couple minutes before I start the car.
1.key in the ignition.
2.turn the key till system starts.
3.wait 2 minutes
4.start the engine.

I never hear the cam shaft variator noice no more. And it has been 3 months since then!
I know nothing about mechanic. And I am not really sure if it is considered “fix”
Hope someone with more experience can share their opinions here.

Letting the car sit before starting will not help a variator noise...I'm not sure the noise that you were hearing previously was the variators if it seemed to go away..Jason

It was a heavy tick noice last about one whole second when I start the engine cold. I can hear it inside and outside of the car.
Very short but sometimes heavy, sometimes light.

Kinda tough to interpret noises over the internet based on just written descriptions ..maybe a sound clip could have helped .. “ light “ ticking or tapping for just the first few seconds on a cold start could be the valves / lifters , but as for heavy ticking I would not have a clue.. And while I’ve heard a lot of valve ticking , I’ve never heard a variator tick sound , so I would not be able to compare . Just very surprised leaving the key in the ignition longer would cure anything of the sort .. IMO, just a weird coincidence , but I could be wrong ..

Is it possible when I put the key in the ignition, the system starts to pre-lubricate before the engine start?

I was thinking that, but you said you only did it once, and that it resolved the issue for the last three months .. or are you saying because it worked back then you’re leaving the key in the ignition for two minutes every day since ?

I do that every since then.
Every single time and never hear the rattle once.

Oh, I misunderstood then. Hmm, that’s interesting.. in that case I have to defer to expert mechanics on this forum ( like Jason for one ) for what the connection could be . I’m curious also.

This is why I love the internet...141 views so far of straight up BS...There is no magical little pump that comes on when you let the car sit...The variator issue is a mechanical issue...Leaving the key on only powers up the sensors and electronics...The OP car most likely had some kinda of lifter clatter etc. that simply cleared itself up... Just ridiculous...Jason

Like I said before, I am no mechanical expert. What’s the sounds difference between lifter clatter and variator noice?
For a long time I thought I had a variator issue because I had the video sent to Service Department in Mike Wards Maserati Denver. They told me it sounds like a variator to them. Ever since then I thought I am the victim of this well-known issue. However I never sent the car to the shop therefore they may be wrong.

Let's start with this...what year is your car? As Jason has said, there are no pumps...especially an oil pump...that starts pumping without the engine running. The engine oil pump is mechanical, not electric.

A varaiator noise is a loud clacking sound for a few seconds on startup when the car sits for a period...I imagine your car had some other kind of slight engine noise and it has cleared itself up..Leaving the key on is just a coincidence in this case as it literally does nothing when you just sit there except send power to sensors and read the values..It sounds like you are just lucky in this case....Jason

So here is a theory. Feel free to debunk with facts and experience. What if a variator solenoid is failing and decides to "do what its supposed to do" when it feels like it, which is only after a pause with the ignition on.

Yeah, I love internet theories...The varaitor has a locking pin that is not locking and that is why they rattle...That is not theory, a guess or my opinion...It is a fact...That is why there is undated variator unit with a large spring that makes sure they return to the home position and lock...I know this from actually seeing both with my own eyes...Not something I Googled...I'm pretty much done with all these variator post...The theme is the same...Some jackass theory not to spend the money to fix them...I get it totally, but mermaid farts and pixie dust isn't gonna fix the problem...The updates will.....Jason

OK...since it's an 08, there a high likelihood that you have the variation problem and, as Jason said, the ONLY way to resolve it is to have the update performed. NOTHING else will work. Period...end of story!

I only brought up that "theory" because some people have said their variator rattle was fixed with only replacing the solenoids. Its all hearsay, and no I dont believe that leaving the ignition on resolves any real problems.

We could keep going on and on...In closing, leaving the key on doesn't do dick to fix a car with bad variators...Everyone enjoy their holiday...Jason
