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.

There's launch control on 6MTs??

Good point. I'm not a Launch Control guy, so I just shined it on. Wouldn't really make sense now, would it?

I was sort of surprised that the service was so limited, though, given what I thought I had read on the boards...

[D CHOI]

Yea I'm a lil surprised too that the service was limited to those 2 things. No oil filter replaced?

BTW how's life with WOT above 5,500 RPM?

Alex is the best of the best SAs and I would trust what he says.

[doug_999]

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.

Yes, I believe they cleared my service notification, but that ain't "unlocking" more power, etc., that I'd read about on this board and elsewhere.

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..

Yes, I got a new filter. And a new drain plug for the diff. So there's that.

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!!!

Sorry, I realize it's a noob question, but what does WOT stand for?

Wide open throttle

[gmzanatta]

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.

[TSMD]

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

[Dabozo]

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).

[M2 Belgium]

I did WOT pre break in service and after.just recently. No difference at all, still good though :-)

[BruceM]

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.....

what week was yours produced? i was week 42, went in for my 1200 mile service last week, and experienced the "can crunch" noise a lot, as people have posted here on the forums.

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.

Week 43. My tech did an inspection, and immediately determined that 1) I did not have the new backing plates, and 2) that I needed them. In addition to swapping out the plates, they actually have the ability to back them away from the rotor a bit more, and they do that as well, to ensure that if rocks get in there they fall out easier.

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?

If you dont go WoT you won't experience the torque overboost effect, will you?

Personally I would find a(nother) well-respected dealer for a second opinion. If their answer differs then ask for the old shields when work is completed. If they're the old models then consider ditching the current SA/dealer.

I would assume you need WOT to experience the overboost. It logically makes sense but I never personally tried it.
