"Running In" question

I was reading through both the 1 Series Owner’s Manual and the 1M Supplement Owners Manuel last night and I just want to clarify something.

According to the standard 1 Series Owner’s Manual, under the “Running in” section, it states the following:

Engine and differential
Drive at varying road speeds, but do not exceed an engine speed of 4500 rpm or a road speed of 100mph/160km/h.


However, in the 1M Supplement Manual, it states the following:

Running in
Contrary to the description provided in the Owner’s Handbook for Vehicle, the following deviations should be taken into consideration for your BMW 1 Series M Coupe:

Up to 2000km, approx.. 1200 miles
Drive at varying road and engine speeds, but do not exceed 5500 rpm and 170km/h, approx. 110mph.

Avoid pressing the accelerator pedal all the way down to full throttle position.


So, is everyone running their cars in using up to 5500rpm or 4500rpm? From what I read on here, it appears to be the latter?

i use up to 4500rpm and have not exceeded 170km/h so far

while making some hd videos of mountain road driving the past weekends the only one who overtook me was riding a 200hp motorcycle with an acrapovic exhaust - and he was insane by the way

(oh, and the owner of the biggest bmw dealerships around in his x6M - although there was a traffic jam and he simply needed to cut in in front of all of us )

run in service next week

I aimed for 4500 with occasional stretch to 5500 as the kms accumulated prior to the run in service. I had the service bang on 2000kms.

Isn't there a note in supplement stating that those parameters supercede the regular 1 series guidelines? I thought I remember that in there.

Yes, as I posted above.

The reason I ask is that a lot of people on here appear to be running in their cars at 4500rpm as suggested by their dealers whereas the supplementary hand book suggests 5500rpm.

Gently broke it in over first few hundred miles, pushing revs higher and higher upto 5500RPM. Didn't straight up to max allowed revs in other words. Only once brakes and tyres bedded in did use it more like an M car. Still easy on gear changes as 1M manual states it needs be worn in too.

Have used the M button a few times now. I find it hard to not to hit the accerator stops. My Honda had much longer travel. But getting used to it.

Cars will be fine. Someone posted that you should do plenty of mixed driving to avoid glazing the cylinders? So for that reason even on motorway I run the car at different speeds where allowed :0

Best not to be too careful with the revs as you'll end up with a slow car. It's more important to vary the speed and type of driving and not to labour the engine.

the first 800km i drove it gently and shifted around 4000-4500rpm. I try to avoid the autobahn. Today i pushed it a little and it was so much fun. But i never did exceed 5500rpm.

Don't think any of it make a difference on modern engines. Drive it hard so the rings form a good seat. First 100km important, then change the oil & filter.

I have followed this approach in my past few cars & bikes. I never took my 135i over 6,500 rpm for first 750 km's & crucial that the oil is hot.

I used this approach on my 2008 BMW R1200GSA bike. The bike runs better than other R1200GS's in my group!

Obviously the 1M specific information contains the "correct" procedure.

My M-dealer told me that most important is to vary the RPM. I took mine to around 5000 rpm during the first 2K. I also did use the M button once or twice. Felt guilty doing it though... They say that the 170 km/h max is mostly because the differential needs running in too.

The limitation may be more related to other components such as the drive line etc. Can't follow a hard running-in process on the 1M anyhow as it is limited to 5,500 rpm isn't it until 1st service?

Each to there own, as said this is a controversial topic.

BMW factory video below 02:14 - 02:25: "In the rolling-road test the vehicle reaches speeds up to 120 mph while technicians examine the engine, exhaust and suspension".

Why would a German dyno read in MPH ??? Think about that.


Also...

I don't think the cars go that fast in the enclosed dyno room - not at Leipzig. I think only up 120 or 130 kph. Thats wha I remember from one of my tours there.

Part of the confusion of whether to adhere to the 4,500 or 5,500 rpm rev limit could also come from BMW "cut and pasting" the 1M sup book (directly) from the M3 owners manual. Everything was rushed with the 1M to get the car to the customer.

All I know IS my SA (and I saw it written in the German owners manual) says V-max of not more than 170 kph and no more than 4,500 rpms for my N54. Why would the 1M N54 be any different?

What about all the press cars for the 1M promotions. Most of them would have been driven really hard from new, possibly even had the rev limit removed?

Someone who tested a 1M test-mule over here reported that, with merely ± 9000 km (5600 miles) on the 1M odometer, the transmission was already slipping ! Talking about car abuse. Okay, the engine is rock-solid and they replace several parts once those test-mules are put up for sale (if not recalled, dismantled and/or destroyed), but personally I wouldn't fancy getting a trashed around car, even if offered at an attractive price.

I actually heard that all of the press cars were going to be crushed rather than sold on once they were finished with.
