Avoid Kickdown During Break-In Period?
What's a kickdown? On P.188 of the Owner's Manual, it says:
"Up to 1,200 miles/2,000 km Do not exceed the maximum engine and road speed: ▷ For gasoline engine 4,500 rpm and 100 mph/160 km/h. Avoid full load or kickdown under all circumstances." Z. |

"Kickdown" is when the transmission downshifts because you hit the gas. They want you to avoid it during break-in. With an eight speed transmission, it's hard to avoid.

I think the kickdown is a button on the floor beneath the gas pedal that depresses when you push the gas pedal all the way in. It signals to the ecu that it must downshift if possible and go up to the max revs of the engine.

Pedal to the metal:
The electronic gearshift control ensures that gear changes are executed without any loss of tractive force, adapting the timing of the shift to suit the current driving situation. The intelligent electronic system takes into account the driving style, whether it's winter or summer, whether a trailer is being towed or whether the road is at sea level or in the mountains. It also notes the speed and position of the accelerator. If the driver presses the pedal past a perceptible resistance a kick-down switch automatically changes to the gear that allows the most optimal acceleration. The precise adjustment of the gear change processes enables a unique combination of sporty and dynamic driving and low consumption. |

I have been hearing for years that the 'break-in period' is a thing of the past and no longer necessary. There's certainly a debate there, and BMW hasn't felt compelled to take it out of the manual (again, the lawyers... ?). But I've not worried about that in a long time. Mind you, I only keep them 3 years or so, but I've just always been told, going back probably to my first BMW in '99, that modern engines just don't need this and they already go through extensive testing before we get them.

Another philosophy is the Mike Miller (MM) maintenance schedule ( MS) wrt maintenance. It is interesting that new for the MY2014 is the shortened recommended oil change interval. MM does say that his recommended MS only reaps benefits if one keeps the car for 100,000 miles. Last edited by barcelona; 12-20-2013 at 07:42 PM.. Reason: i think beyond 100k |

Yeah I thought the change from 15 to 10 was interesting too, after all these years of 15.. Then again, I was also surprised when my F30 didn't say it was due until 18,000 (a lot of highway miles in a short time frame, car senses the type of driving so gave me longer). Yet, if I bought my car a few months later, it would have told me the very same car with the very same driving needed service much sooner
