Hello,

One of the things to I had to get used with the VN is that the car still runs a bit after I stop it and get out. I know now that's normal, and the car has been just fine.

Is it OK to close the garage while the car is still in this post-drive running mode? Or does that run a risk of carbon monoxide in the garage?

The vast majority of times, the car is completely off by the time I get to the garage door opener. But a couple of times it's been close.

Thanks,
- Joe

The only thing to ever stay on for a minute or so on my N is the fan. But the engine is always fully off the instant i press the button.
I've never seen or heard of a car let alone an N that still runs when you turn it off so im not sure whats going on here but im intrigued

I'm pretty sure it is just the fan. I've never opened the hood to find out to be completely sure.

So I can close the garage while the fan is still running, right?

Could also be the water pump, mine runs a minimum of 2.5 minutes after every warm shutdown. Fine to shut the garage for either.

 

[MikeMr305]

Yes, as long as you turned the engine off the fan is running off of just the battery so it is fine to close the garage

Glad this is normal. My fan ran for a good minute after shutting off. Lol. And my hard starting issue is getting almost every day now. At least once. Guess I'll go back to dealer

Back in the day they used to sell a "turbo timer" that would do the same thing. It would continue to run the motor for a short while after a drive to ensure that it has time to circulate the oil through the turbo to cool it off and increase the longevity of the parts.

Yea I actually hear something else run fo around a minute after I shut it off. Not the fan. Something quite. Maybe that is what it is

I've just been playing it safe and let it idle for a min or 2 every time before I shut it off

Back in the old days before water cooled turbos that's what we did to keep them from cooking the oil. If you had a turbo, the best practice was to start it and let it idle a good 30 seconds or so to make sure oil reached the turbo before getting into it. Allow the oil and engine to reach operating temp, and then drive as you wish. If running normally (day to day traffic) allow it to idle a good minute before turning off, if running hard two minutes. Or you could buy a turbo timer to do it for you.

My previous car ( fiat Abarth) had an after run coolant pump and I would hear it run when I shut it off. I can’t remember ever hearing that on the N . Is there something I need to look at or if I open the hood where is the source of this?

Yes, you're alright. It's just the turbo coolant pump. Which is a normal sound for the VN.

I have not heard it running. Is it possible that it is not working? Where is it?

You may not hear it unless the car is pretty warm. If you know you're headed home for the day, get into boost and have a very spirited drive on your way home. I'm pretty sure if the car is hot when you shut it down you should hear it.

Okay I think I have almost doing it for the car by driving the last few minutes calm and it is not tripping it on.

It perfectly fine to just shut if off after a hard run. The OEM turbocharger is both oil and water cooled and the pump is there to aid in cooldown. There's no issues either way.

If you do not hear the pump running, it's simply working at a different volume and rpm or If the turbo temp is below the set temp for it to run, it won't need to operate. Hence, the turbo doesn't need the cooling assist. It's not like the old way and requirement of letting the turbo spool down and cool off, before the engine is shut down.
