Is this the dreaded "Chain Rattle"
Bought my 2011 Mini Cooper S R56 (N18) about 2 months ago. The car has 61,000 miles on it, and by the records that came with the car, has always been well taken care of.
As of the past week, I've been noticing that on cold starts in the morning, motor is extremely loud and with the hood open, seems to run pretty rough. Noise eventually goes away, yet still has me wondering what it is.
I've heard of the cold start issues, but I'm wanting to know if anyone thinks this is the dreaded chain rattle, I am not sure if the chains and guides have ever been replaced.
The car is still under the extended warranty that the previous owner purchased, so should I take it in? I just don't want to sound like an ******* to the dealership.
I did a video of it this morning, temp was about 11 here in Jersey. Video is below, and any input would be greatly appreciated.

The N18 engine, like the one you have, does not have that issue per se'. when i start my car 08 clubman, i hear the same noise and then it goes way, and im down in philly. You can always take to the dealer for any reason you want. let them know that there is noise in the engine and let them see the video. the warranty is there for a reason.

Oh okay, I wasn't aware that the issue pertained to N14s, as you say, per se'. Just seemed a little loud and violent to me. Oil was just done by the dealership, so I know low oil wasn't an issue.
It goes away like you said, but only when I let it warm up for awhile. Taking it to the dealer won't hurt, just wasn't sure if they like to charge just to look at something.

It's hard to tell for sure from the video, and maybe it's just me, but it sounds just like the normal valve cam noise to me with these little engines... I'll be curious to ear about what the shop as to say...
They are small, with thin wall sections, so they don't have a lot of natural noise insolation to start with...

Little update, Dealership finally got back to me around 3 today, after having the car all day. Service guy stated that the tech went out to the start the car, mind you it was around 3, and didn't hear any noises.
I usually start the car at 6 in the morning, when it's still blistering cold out. I told the service guy this, and also said that the video clearly shows there is some unwanted noise.
They are going to keep the car overnight again, and hopefully start it first thing in the morning.
Until then, I will continue to drive my brand new Chrysler Pacifica courtesy car (yes, I am driving a Mini Van)

Lmao, thats a good one, never thought of that. I see why people get Mini Vans, thing is loaded and comfortable.
But no, I was thinking that same thing. I'm not even sure if the car was kept outside or not. I should have thought of that earlier. I'll ask tomorrow and find out for sure. I'm not just going to drive my car out of the dealership with nothing done, just to have something happen weeks down the road.

Dealership just called, so so far, they replaced the oil pressure solenoid. Service tech stated that the car is still throwing some sort of codes for oil pressure. So now, I'm waiting on them to install an oil pump.
Is it just me, or does anyone else think they are doing all this to avoid replacing my chains? The car has never thrown any check engine lights at all for oil pressure.
