It's the rear diff that is the issue during break in. At 1200 miles it will be good but the special dirty break in oil needs to come out before you start railing on it.

I've posted before - the 1,200 number is not magical - going a few hundred below or above would be no big deal in the real world.

However, the OP is correct -it doesn't take much for BMW to deny a warranty claim and it would suck if they did because "you brought the car in 200 miles past..."

on another note, I was going to buy a M3 once (long time ago) and my dealer ran the numbers and saw that the guy had gone like 3,000 miles past the 1,200 mile mark. Passed on that car!

Yeah, warranty is another concern. I would pass on a car that went so far past break-in too. It's crazy especially when it's free on top of it. I hit 1200 miles in Germany on ED. I took mine to a dealer in Munich and paid out of pocket to get it done. The next day I finally opened it up and hit 150 on the Autobahn. When I got home, I gave my dealer the receipt from the Munich dealer and they reimbursed me. I also had the gearbox oil changed which they had stopped doing in the US at that time but I got reimbursed nonetheless. It was great.

I also spent a couple of years working in an IMSA GTP factory team dyno. We broke in motors prior to the races.These were hand built motors with tighter tolerances than massed produced cars and more expensive components and yet they were carefully broken in. We then filter the used oil and look for metal particles as there were a lot of them.

I would say that if you really wanted to do it right, you would change the oil and diff fluid (and the gearbox like you did) much sooner than 1,200 miles.

and as far as BMW recommended break-in procedures - well, I won't start that argument - I mean "discussion" here

Exactly.
No one chimed in on my question. Does the dash indicate that service is due at 1200 miles??? My service indicator shows service due in 10,000 miles on my new car. The break in period is hardly even highlighted in the manual. Critical event? Hardly. If it were, BMW would highlight it much more dramatically.

It had an alert but it was on the center console screen as a notification about the car. I have a picture of the car dash at 1199 miles and it doesn't say anything about service needed, but maybe that only happens when you turn the car on? When I turn the car on now it tells me I need one at 10k miles.

^^^^This is the only issue for the M2.

Otherwise it is no different from an M235i!!

iirc the only major difference is the M235 does not have an M diff and no 1200 BI service requirement!

Nothing "magical" happens at the 1200 mi break except for launch control being enabled for DCT vehicles

There is a little mark in the upper corner of the iDrive - might have been red - see attached picture (not from my car, just one I found on-line)

This goes away after you have your 1,200 miles service done.

FYI, you'll screw up your warranty if you go past 1500 miles.

Based on what? Tell me where inn the manual it states you are required to have a break in service to maintain your warranty.

I did PCD. Since it was 1700 miles from there back home, I asked if that would be a problem, and they told me explicitly "Yes." They said 1500 miles was the absolute hard limit, and that BMW could void the warranty if that was exceeded. I arranged with a dealer on my route (BMW of Lincoln, NE) to do the service during my drive home. I was at 1210 when I got to the dealership, and they had me in and out of there in 90 minutes.

I'm going to rtfm. I'm really curious where the stipulation is.

My MY17 (Nov 16 build date) counted down to my 1200 mile break in service every time I started my car. Now it counts down 9k miles till the next service every time I start the car. My last BMW started the count down/reminder 1K miles prior.

On a side note, the Nav vehicle info did state the 1200 mile service too.

Bet you won't find it. Because they can't deny and/or terminate your warranty just because you didn't service the car at 1,200 miles.

However....
In the event of an issue with the differential or a component of the engine that is lubed with oil, they could deny that claim. Kind of like the Dinan stuff - BMW covers everything not touched by Dinan and Dinan covers the rest.

Yeah, re-reading my comment above, I wasn't clear. They didn't say they'd void the warranty on the entire car, but they did mention that diff problems might not be covered if I didn't get it serviced within the recommended interval.

[Wangspeed]

If you go past 1500, the car is no longer valid for the certified pre owned program, warranty becomes non-transferable, and I think ruins the warranty on the diff.

No way. No chance. Did anybody else get the little owner preview attached to your gear shift? No mention of a break in period.
My car is a March 2017 build. No break in indicator. Indicates service in 10,000 miles. I don't think anything in the manual refers to a service either. Perhaps BMW changed the requirement.

This just seems too weird. I would ask the dealer - because there should be a count down and indicator.

I received the little owner preview, and yes it was attached to the gear lever. I also had the car counting down to the 1200 Mile service. In fact, I had a service notification of 1200 Mile approaching soon from the moment I first started the car at the dealership.

Ooops... I did my service today at 2490 km. (1547 miles)

I sincerely hope the limit in Europe is an even 2500 km.

I'm back to this thread. No warning. No little indicator. Exceeded 1200 miles. I've made a dealer appointment and they cover it of course. Makes sense to have it done, of course as BMW covers it anyway. I wonder if they made a change in 2017 cars. It is still in the manual however.
Also must say that I've checked the diagnostic screens and they indicate no issues and no service required. Pretty weird, right?

My May 17 build counts down to service for the break-in... Go to 'notifications' in iDrive and it should be there... I did code to idrive 6 light though.

More so in the electronic owners manual that I just downloaded for my car on the BMW Driver's Guide iPhone app, clearly states "Breaking-in period" which goes on to indeed tell you 1200 miles.
