1200 mile service observations
So, I just went in for mine. This is what the SA told me (Alex Long of Seattle BMW):
The service entails new engine oil (0-30 spec), and new diff oil. Period. No software tweak, no enabling of Launch, no nothin'. He says Launch has been enabled all along. He also says the diff oil fill is the same stuff that the car left the factory with. Separately, I described for him the horrible racket my rear brakes made one day when I was driving in my firm's garage (but not to my ears before or since.) He checked it out, and is authorizing a repair that involves replacing the "backing plates," which in turn requires replacing the bearings. Covered by warranty. Would cost $1500 to $1800 if not covered. Should entirely eliminate the noises, he claims. Nothing to do with the diff, or for that matter rocks (although he says rocks can get in there and cause their own noises.) Says maybe 50% of M2, M3, and M4s have had that same repair done at this dealership. |

They obviously do something with the computer - since we have that icon on our iDrive until the 1,200 mile service is done.
and speaking of rear brakes - mine make a terrible noise when backing up. Is that what you are talking about?

Very cool dude. Has an e36 race car, and has raced wheel to wheel for years. Also owns a Cayman R. Knows cars and likes talking about them. I almost always prefer talking to service guys over sales guys. A few exceptions (my sales guy for the M2 from BMW Montgomery was good), but often those dudes are just about moving metal, as opposed to knowing or caring much about it. |

Your back-up noise could have the same cause as mine, although I heard mine moving forward. Alex says in so many words that it is a design flaw that can be fixed with the procedure I described.. |

I'll tell you about life at WOT when the roads are dry enough around here to live that life! Very frustrating. Gotta seat the rings!!! |

Hmm not sure I agree with the diff oil thing. The break in oil is quite a bit thicker to catch all the particles and etc. Wish I'd taken samples, oh well.
As for launch control, pretty sure that's for DCT only. I have 6MT too, so can't comment if it was enabled at the start or not. |

My 1200 mile was done recently and all I can say is life wide open above 5500 rpm is good. Mine is DCT and drivers package SA said they enabled launch and top speed when it was serviced. I have tested both since but only got to 160

Any 'performance ' gains post-1200 mile servicing is complete placebo effect.
Not to mention most won't go wot before break in so you have nothing to compare to really (pre/post break in service). |

Roads dried enough here to do some good WOT pulls, at long last, to establish a good "butt memory" I can compare with the pulls I do after the Dinan kit goes in this next week.
Car pulls very nicely in 2nd and 3rd. Felt like it ran out of grunt a little in 4th, but I had to back out pretty quick each time. Will be interesting to see whether or how much the Dinan big turbo changes the characteristics of the response up and down the rpm band in different gears..... |

Showed my SA the part numbers and all that to have the backing plates replaced but the tech claimed I already had the updated ones. Still experiencing the issue a lot. |

I would be very surprised if your week 42 had the new plates, based on this. Also, my tech said he had no reservations based on cost to make the change--said his dealership was paid by BMW for warranty claims like this, and as far as he was concerned, he was happy to do this swap "every day," if it is called for. Did you tell your SA the BMW measure number for the procedure? |
