Yes I am holding the brake pedal down firmly, and as soon as I floor the gas PAST the kickdown switch (click), the car is trying to push forward which is not good as that means the transmission is engaged, and not in LC mode. I guess I'll take to the dealer, however I bet its something they did not add/update when the car was delivered..

1- Warm the car up and drive a few miles
2- place car on SPORT+
3- Place the shifter to the left side position (sport)
4- Press the brake pedal firmly all the way down, At the same time press the gas pedal all the way down. The car should not be moving forward if you are doing it correctly. You will have 3* seconds to release the break and launch the car. A flag should appear on the cluster to your right hand side.


If this is not clear enough then i think you have a lemon or a defect.

I understand the reason for the 3 seconds, but out of curiosity, does the car enforce the 3 seconds or is it up to the driver?

You want to make sure you are flooring the gas pedal quickly, this cannot be a gradual push.

Yup following all of the above, with no luck. Dropped it off today, lets see what they come back with.
On a sidenote, I'm in a new 535i loaner. Impressive power and efficiency for what it is, however these cannot even remotely be compared to the N63tu motor.
Many told me to check out the 535i when I was in the market, but its not even in the same ballpark. The muscle of the V8 in the 550 is something else, and after a day with the smaller engine, I'm bored already!

Agreed. I had an e90 335 (N54) prior to the 550. I thought I'd be happy with the 535, even though I knew the extra weight would make it more sluggish. I was about to commit to it when I threw economy to the curb and test drove the 550. Upon coming to a stop light, there was an idiot in a Camry who wanted to beat me off the line since the two lanes were merging. Normally I'd let guys like this go... but it was a test drive and a nice opportunity (excuse) to floor it and see what the fuss was about. Well, let's just say that's what sold it.

I'm at 1,000 miles now, close to complete with break-in and looking forward to playing more liberally with this car's power... including testing launch control.

If you don't mind a few extra bucks at the pump, I think the 550 is the perfect compromise. I say compromise since most 550 owners really want an M5 (at least I would have) but needed things like xDrive and a more compliant DD ride, etc. If the next gen M5 has an xDrive option, it may be the perfect 5er. Until then, I think the 550 really gives you amazing power and comfort in an easy DD car.
