Break-in period strictness
Hey guys!
I picked up my new M2 on Monday in Munich. The person that gave me a tour of my car and showed me all of the systems and everything told me that, while there's a break-in period, but she seemed to suggest that it would be okay to break the speed restriction (I stayed under 5500 though). So, I did, just like 4 times though for brief periods. Is my car going to explode (lol)? How strictly did you guys follow the break-in rules? Also, the Nurburgring was tremendously fun. I strongly recommend it for anyone who is going to do a European Delivery. |

I ramped up my engine speed and throttle usage as I got closer to 1200. I started upping the load on the engine after 800. Runs strong.

Probably not the answer you're looking for, but wouldn't it just make sense to stick to exactly what the BMW rep said? Losing your warranty and/or potentially causing damage to the car you just spent a whole bunch of money on doesn't seem like the most propitious start with your vehicle. Stay strong, and drive it like you stole it when you break 1200 miles.

Ehh I wouldn't worry much about the max speed restriction. The big one is avoiding WOT and <5500rpm which lends well to piston seating.

On the point of WOT, if the M2 is anything like my 135i, you don't need to get the gas pedal anywhere near the floor for 100% throttle.

One of the theories is that break-in oil is different - lasts shorter and provide less protection. Therefore better do things less crazy.

What??? You realize that the rear axles go into the differential and they spin at the tire speed that you are going. They say not to exceed a speed to keep heat down as the thicker break-in oil likely doesn't lubricate good enough above that speed! I would not exceed the speed. More so over WOT.

Here we go again...
Drive it. Don't get on it until warmed up Go easy on brakes for first couple hundred miles That is. People are so crazy about this 5,500 rpm thing. Do not fret the car will be fine.

Ha! I didn't mean to start an argument. I was genuinely wondering what damage I could have caused to my car by going hard on it for a Nurburgring lap and for a pull or two on the Autobahn. It seems there's a lot of speculation about what exactly is going on during break-in, but there are no real concrete facts. Most people just say something along the lines of, "It wouldn't say there was a break-in period if there wasn't." That said, I plan on taking it easy for the rest of the trip. Thanks for relaxing my nerves! |

My mechanic is an ex-BMW tech who started his own shop 18 months ago. His advice was to not sweat it too much, but to have the 1200 mile service done before really getting on it. Even if that meant doing the 1200 a tad bit early.

Yes, that is the M Laptimer app. I couldn't get it to work with my iPhone while on European Delivery, not sure why not.
I tried to follow the break-in procedures but a few times needing to pass meant the 5,500 rpm limit might have been pushed a bit. I did a group trip with a bunch of other BMW Canada customers and we our leader was an ex-BMW test driver and ex-Ring-taxi-driver, he told us for the first 2 days (around 500-600km we should try to stick under 160km, then after that 170-180 would be alright until the break-in service. After I had the break-in service the manual does say to still keep it easy for a while but I couldn't stick to that very well since I had to get to the Nurburgring, I hit 255km/h on the Autobahn there, then did 9 laps of the ring (8 Nordschleife, 1 GP+Nordschleife), then Autobahn to Hamburg this time only getting to 240km/h. Ugh, that traffic and construction was painful! |

This is the built in BMW Lap timer. It measures not only lap times, but g-force, rpm, speed, corner speed, throttle position 0-60 and maybe even more that I can't recall. It automatically recognizes the track you are on. You can overlay different runs. Pretty cool for a built in app.

All cars get it (as long as you get navigation and connected drive). My 2013 F10 535i can use the M Lap Timer via iPhone

Video can be captured with the GoPro (also an app on Connected Drive) and can be combined with the lap timer. I personally haven't done that, but one of the instructors combined them with a lap at Thermal (Adam Seaman). This session shows up on the iPhone M Lap Timer.
