Launch Control
Does anyone know when and how Launch Control on the M550i is available for use. Does this feature turn on automatically after a specific number of miles/kilometers?

I had to look it up too, apparently sport plus doesn't turn off traction. Proper procedure is.
- First of all make sure you've driven at least 10km so the car is warm - Put it in sport/sport plus - Click the traction button to turn DTC off (key part which i missed) - Gear lever to the left in DS mode - Mash the brakes hard - Simultaneously Full throttle and you should see the checkered flag appear. Leave it after about 3-5 seconds and enjoy your 0-60 in 3.9 seconds

I don't remember very clearly but I did try LC at around 1800km's and it did work, after I followed the procedure properly that is.

The only break in period BMW has is for pure M models, nothing for standard models or M performance. So features do not magically appear after some mileage milestone. I asked about this when I picked up my M550i and the response was go have as much fun as you want. That said, I think it's prudent to go easy for the first few weeks rather than trashing it out of the box.

There's a breaking in period for all cars whether they are M or not. That said it wouldn't stop you from going over those RPMs if you want to.

Actually with modern engine designs, the "requirements" are less and less... My sales associate's response of you don't have to do anything didn't seem strange to me as I got the very same answer 3 years ago regarding my F-Type R....

- Take it easy for 100 mile to bed in brake rotors and pads - Vary RPM for the first 300-400 mile. - For us, 400 miles was about 2 weeks mark, I start to go higher and higher. - There is no need to hit redline but I got way up there after 600 miles on engine. I take it easy every morning for engine oil to warm up before take it higher up in RPM range. Beside, I have to wait for my brake pads and tires to warm up anyway before gunning the engine. Cheers, |

Here is a screen shot of the manual, it says do not use LC when running in. So, it is technically possible. This is 540i though, M550i might be different.

So this LC thing really freaks me out, but I’m interested in trying it at least once. Tonight I did try- I followed all the steps, but on the last part I pressed the brake hard with my left foot and started to press the accelerator... and I felt the engine lurch a bit as it struggled against the brake, just as you’d expect an engine to do in such a circumstance... I didn’t see any checkered flag, and I instantly backed off. Maybe I did it wrong? But it did lead me to wonder if it’s better to just mash the gas pedal all the way too?? And if you try this, is the idea that the car doesn’t engage the clutch (while the engine is at optimal RPM) until you release the brake? I think understanding what the car is actually doing would help ease my mind. Hopefully my little experiment didn’t damage my car at all!?? 🤣😬 Any ideas what I did wrong??
