Hi folks,

I purchased a 2019 F80 CP back in Oct 2018. The launch control does not work (i trued it with the dealership foreman several times). Another issue is the auto on/off; sometimes when I let my foot off the brake, the car comes back on but turns off back and I have to manually turn it back on then put it in drive to move. I took it to the dealership, and they said there is nothing they can do as they cannot repo the issue (I have it on the dashboard cam, but they don’t care and told me they have to see it happen). What should I do? The dealership already tried to fix the LC (the car spent 2 weeks there), then BMW sent a factory rep to check it out, I refused to let them drive the car without me being present, so they said they have to repo the issue. I already tried it with the dealership’s foreman several times, no luck
The sequence to launch the car is
DSC completely off
Transmission in S3
Engine in sport plus mode
Mash the brake
Mash the throttle

No luck.

P.S: when the car is in auto off/on, it turns off become a complete stop too, like at the speed of 1 MPH.

I mean ... to start with the obvious ... did the dealer perform the 1200 mile service in which they activate launch control as a feature? Seems like most likely culprit is that somebody botched that service.

They probably did botch the service, but, yes, they allegedly did the service

I assume that the car has been driven for long enough as well? IIRC there is a 15 minute period where the LC will not activate when the car is turned on.

Try putting the suspension and steering in sport plus as well. Manual says everything in sport plus dsc off shifts at manual and set to level three.

Suspension and steering do not have to be in Sport+ to activate launch control.

FYI- L/C is ready from the factory and NOT released at the 1200 mile service

We did try everything in sport plus. The car was driven for 30 minutes before trying the LC. What is worrying me is how the car turns off with the auto on/off.

That is correct and confirmed

Tried that, it’s not required, but tried it just for the sake of it

Yep, that’s what i did.

Since no M cars have ever needed service in order to activate the launch control, I don't know why this would be "obvious". The car starts allowing LC at some point somewhere around 1200 miles. It could be 1250, it could be 1300, it could be 1150. And it has nothing to do with whether you have had the service or not.

No cruise control RPM adjustments on the F90

You can do launch control with 0 miles on the car.

No, I don't think so. I don't have mine yet, so I could be wrong if they have changed things, but as far as I know, as I said, the car will only allow it once it reaches the magic number in the computer, which will be somewhere near 1200 miles. It isn't necessarily exactly 1200 miles. It is probably similar to how the engine computer informs you of the need for an oil change service... It's actually based on how hard you have driven, how many rpm's you've racked up, maybe temperatures at which the engine runs as well as mileage. In other words, people have often wondered why their BMW's service indication came up sooner or later than the standard mileage that they expected it to come up. It is because the computer has some kind of magic formula that it looks at that is more than just odometer mileage. You are supposed to get a 1200 mile service where they change the fluids. You are not supposed to drive it hard (or use launch control) until you get the service. But just because you got the service doesn't necessarily mean the car will let you do a launch. You might get the service at 1100 or 1150 or even 1200, but it might not let you launch until 1250. Or, you might not get it into a dealer to get the service until 1300 or more, but if you tried it, you might find that the car will let you do a launch at 1200 or 1250, even though you haven't had the service done. I don't have my M5 yet, but that's how every BMW I've owned has been for the last 15 years.

It is not recommended, but can be done with 0 miles.

Car will prevent if you have not warmed up.

OK. That's different than it used to be. Since I don't have one yet, I'll just have to take other's word for it.
