Hello Everyone,

My 2000km (1200miles) break-in service is due in 1000kms. I was wondering if any of you really could feel the difference in performance between pre and past service, or it is just a BMW marketing BS?
If you could describe the feeling with numbers e.g. +10-20% power, it would be most appreciated

My CA alluded to this being real, but not sure if this is just something he was parroting or really knew. I think the difference is you’re trying to stay below rpm limits and a lot more power is on tap when you lay into it. Makes it seem like two different cars.

Allegedly only if you have the drivers package, they raise the speed limiter after break-in. I didn't do any top speed runs until 2000km, so I can't confirm

Agreed. I was very careful with the 1200 mile guideline. Recently (>1500 miles), I’ve put my foot heavy into the pedal and, damn, it feels like 2 different cars. The car is a monster. YMMV

There’s been multiple threads on this where BMW technicians have confirmed all they do is change the engine oil and filter, and diff oil.

They don’t unlock the higher top speed (if the driver’s pack is optioned), they don’t unlock ‘launch control’, they don’t unlock higher RPM within the engine.

You can do all of the above from the moment you drive off the forecourt if you want, it’s just not advised or part of the ‘running-in procedure’.

I have trouble believing this to be true. I assume that is controlled by the ECU and that would mean the dealership would be unlocking the ECU...and that is not happening.

Fluid and filter change. But gives the green light on the right foot so that's the performance difference

Break-in service from BMW tech guy.

Nice video and great to see the whole process and get the explanation behind everything.

Shame you didn’t show the tech updating the car with the BMW software as he said he would explain more about this. I’m still not convinced on the power being held back in ‘run-in mode’.

Keep up the videos!

Here is another perspective from another BMW tech.

Myth. M drivers package comes without 155mph limiter from factory.

[JABCAT]

I can't tell you if there is anything from a performance improvement standpoint. The SA told me they finished the fluid changes and were just "finishing up the new programming" when I was waiting to pick it up. I also noticed on my paperwork they replaced the rear diff "screw plug with o-ring" though the tech in the second video said that was not necessary.

Because I have the M drivers package and spoke with many M-Tech’s I know around town about it, as well as inquiring to BMW N.A. Online about it via email.

The only thing they do at service is what you see in video above.

Specifics of what you order on the car are done in-factory. I did not take my BMW M2 to the same dealership I bought it from, I can imagine some dealerships not doing the “de-limiter” on accident if this were the case.

Every de-limit drivers package tune is done via software straight from SLP Mexico plant for the M2.

We know no software update/change is done, but that's not a requirement for the condition to be true. So you're saying you didn't test it yourself? Without testing it there's no disproving it. The manual is explicit about it.

I tend to trust that information to be true, and believe the car would only go over 260km/h after the RiS.

No, I didn’t try to hit 177mph and test it.

Lets put it another way...to those with the full carbon package, is there any paperwork or notification that you received stating you had to bring the car in to allow a limited to be "released" so you can go above the stated 155?

Agreed to this. And no, I did not get any notification on my car which has the M Drivers Package.

According to this (which is questionable) at ~9:30 there is PDI (delivery mode) and then "running in mode" for M cars that is in fact restricted. And then unrestricted after run-in mode. That is contradictory to what I understand to be true. Odd.

Me either. They could be ripping me off but at least I finally got the track package invitation.

There has been a lot of conjecture about RIS and RIS specific lubricants (engine and diff). There is absolutely no proof one way or the other.

There is no reason to believe that the speed limit unlock couldn't be done automatically if there was a lock at all. I do agree that dealers are not likely to be the ones to change this setting but they do reset the service interval with the RIS.

Personally I don't see the issue other than as a debate. It's your car, drive at 178 mph with 100 miles on it if you want. Same with an early oil change or whatever - your car, your warranty issues or long term ownership issues.

The manual calls for run-in service, why not do it as prescribed. For those that believe it is German overengineering need to look no further than the Corvette C8 which increases RPM limit and top speed with miles during its breaking. BMW could have done it that way but chose to not. Anyway.

I know what he is saying is not true when it comes to "when it comes out of delivery mode, it's in running in mode, so the car is restricted, whether it comes to RPM or power output" (strange that he just speculates, without any base, which tells me he DOES NOT KNOW WHAT HE IS TALKING ABOUT).

Fact is: car is not restricted in power. Car is not restricted in RPM. The manual doesn't even tell you not to reach a certain RPM, for example (if it did, the car would have been limited from factory).

What is unknown is whether the full speed is unlocked after the RiS, although BMW says it is. I believe it is true since it's so easy to do in the car's programming.

The rest is speculation and very bad ones at that.

That's why it's a myth because of speculation. I think lots of it can be done during clearing the running in service since it's only be done by the dealer's computer. It's probably connected to BMW's. One click on the terminal after connecting to the car, sequences of reprograming can be done.

Stating its questionable is being kind...I call flat out Bull $hit. The video is done "after hours" at BMW, and not an authorized BMW video. There are "special" break in fluids. Oh, best is the beginning that its sponsored by some cf co.pany that makes phone cases? Seriousy? I really didn't need to watch any further and lose any more time out of my life.

All I know is IF letting the car go in the future or trading in for a new model down the road…M Drivers Package will help retain value. I don’t ever plan on topping 135mph even on track, but it’s nice to know we have more in munitions in the armory!
