A mechanic told me that BMW should be putting the car into a particular mode (can't remember what that mode was), whilst they do their checks and move/drive between stealerships which prevents the mileage from being recorded on the systems odometer. No idea if this is true.
I am not even sure if I've ever received a car with 0 on the clock, the minimum was 3miles on a Lexus.

Imagine if that 'mode', if it exists, was hacked? Catastrophic odometer fraud. It would have to unbelievably secure.

I would think a broken in motor for PCD or Euro delivery would be the way to go. You could get on the car full revs with no issue. Really enjoy the car's full capability without run in period limitations or parameters.

BMW might consider that as an option for buyers. It would be expensive I suspect. Either motor on dyno or car on a dynojet for a period of time equivalent to 1k-1500 mile break in. I would like motor on dyno.

They could then change oil and off you go.

M cars have a fluid exchange requirement before 1200 miles.

I have not heard of a engine production that does not have what is called COLD test and HOT test cycles for every motor produced. Typical production will run whats called cold test no fire testing to verify leaks and other electrical components. Then before being shipped to install they run what is called HOT test or engine dyno. This is done for legal requirements to meet specifications. Every producer is different on the time they run them but at CAT they ran in cold test for 19mins and hot test up to 8hrs for a break in cycle. Now once the engine is in the vehicle it must break in with basically the maniacal weight it now moves. I was hoping someone who actually works in the factory would chime in on this convo but there is a legal point where you CANNOT reset an odometer. I'm not sure on BMW but was told typically its at first start, test. I've worked in engineering in many factories back in the day so I'm sure things are changed but maybe someone will read this and correct what I am wrong on.

Yea, agreed on the break in. For those of us doing PCD, it kinda sucks worrying about the engine not being properly broken in cuz we'll be cruising on highway most of the time so we can't vary the RPM as much.

During a trip before reaching the break-in point, I varied the RPM by changing gears to increase or decrease the RPM, keeping the speed the same. Don't know if that is the proper way to do it, but my engine seems to be ok.

That's a creative idea. Would love to hear others chime in if this is a good practice.

Break in is to seat piston rings. There are all kinds of different coatings on bore linings, so I would do what the engineers suggest.

I find this guys videos awesome.

I thought you only needed to 'break in' the high performance M cars?

The owners manual suggest for the first 1200 miles not to exceed 100mph and 4500 rpm and to vary rpm on long trips.

That's what worries me about doing a PCD and road-tripping it back home. I might try to do the manual mode and go back and forth on the gear (without going over 4500rpm). Also won't use cruise control.

With new modern engines, there's rarely need for extensive break in - just not drive like you stole it.

I drove home using Active Driving Assist, testing automatic lane change and other features of Driving Assistance Pro, kept it under 80MPH and 4500RPM - highway cruising ranged from 60-65-70-75MPH.

It's an amazing quiet effortless cruiser - most of the time I forget I'm hitting over speed limits despite heads up LOL.

But I think BMW is still recommending the varying load part... so I'm a little concerned about using cruise control.

Obviously you are free to do what you feel comfortable, and let's face it, we're not gonna be able to get enough evidence for either side to prove what is right/wrong.

Sure and about every car manufacturer recommends similar break in periods and parameters. Having owned BMWs for 20 years, I think a lot of new owners are thinking too hard about break in.

In the end as you said, it's up to you do what you feel comfortable but what I'm saying don't beat your head if you accidentally rev over 4500 or cruise at 3000 for a 100 miles that you're going to mess up the engine break in. Drive it, enjoy it.

I think you can still use cruise... Just vary the speed. Most likely you won't be able to maintain speed simply due to traffic. Unless you're driving through the night.

^ this - the active driving assist wasn't able to maintain consistent cruise speed due the other drivers around you.

And varying speed is as simple as hitting the toggle. Plus you get test the new driving assistance systems to make sure they work.

Agreed. I'm not trying to over think it, it's just that I have a 600-700 mile drive home after PCD (Depending on the route I end up taking), which is like half the break-in period

Yep I put 538 miles for the drive home from PCD and then another 200 this past week. Also great for breaking in the tires for grip.

Since you're going back to Chicago (assuming), I would definitely recommend taking a route that takes you through the blue ridge parkway ... it's amazing.

Did a quick google search, it looks awesome. Any tips to share about planning this route? Yes I'm driving back to Chicago, most likely going the shortest route via Kentucky and Indiana

I'm not that familiar with the route up north past NC. However, if you want to make a road trip out of your return trip, you can go from Greenville to Asheville - spend a day or so in Asheville and visit the Biltmore (historic mansion / winery / very nice) then find the most direct route back to Chicago, which will most likely take you through the mountains, so more fun driving.

BMW does not list varying the RPM as part of the break-in period for the G05, at least for the 40i.

Really interesting find. Must have gotten my info from out dated sources. Sounds like PCD road trip is getting nicer and nicer.

Once you get your VIN, you should be able to get a driver's guide (manual) tailored for your X5. Even if that doesn't work then just use a VIN you find on a dealer's site with comparable features.

Here is a link to the generic site that you can use until you get your X5 and get it on the MyBMW site.
