Sprint Booster has a no-questions-asked 30 day return policy. Installation takes a few minutes (remove 1 bolt and 1 connector). Try one set at max and you will NEVER want to go back to the stock setting.
Good to know, thanks.

I have the Dinan S1 tune on my M550i. Without the Sprint Booster, it has the same poor off-idle throttle response as the stock car. My concern isn't wide open throttle performance - obviously the M550i will smoke the Taurus in a flat out drag race. I'm talking about drivability. My tuned Taurus simply has much more responsive off-idle throttle tip-in than even my Dinan M550i. The Sprint Booster evens drivability up quite a bit, but the BMW's throttle programming simply isn't as well sorted out as the that of the Taurus.

I new to these types of DIY tweaks. Can you explain more about the advantages of adding this? Is this only useful for driving the car "hard"? Or for every day, casual driving it also makes a big difference? I ordered a 2019 540i M Sport. Their website has a note that says it does not fit the 540i, so I guess it's a moot point for me, but I'm still curious what if anything I'm missing out on. Thanks!
 
The rear collision avoidance is a great feature but can be overly sensitive. Went to a Yankee game Sunday and was pulling into a tight parking spot in the garage. The brakes kept slamming on, thought I hit something! Called BMW genius line the next day. Pressing the park assist button will temporarily disable it including the cameras and sensors.

Same thing happened to me the other day while attempting to back into a parking space on brand new, clean pavement. I tried 3 times to no avail. I finally had to turn the car around and pull into the spot.

As much as I love this car - and I do, given all the new electronics introduced into the G30, I would never drive it past it's warranty period.

You can turn off this feature (braking) in iDrive which leaves the other features still functioning. You still have the camera(s) and the sensors working, but not the braking.
Cheers :D

I know and a it's good point. Only issue is for me is that if I need to quickly disable it (like backing out on steep driveway), one click of the button on the console will do the job. You unfortunately can't set a preset to do it but can at least get to the Intelligent Safety iDrive screen.

Were you able to confirm that what the genius told you did work? So just to confirm, if the car brakes in reverse and will not move on its own, instead of manually disabling this feature in the menu, you can just press the park assist button and then it'll back up without stopping? When you say "including the cameras and sensors" - are you saying that the cameras do not work either once you were to press this button?

It's good to know about it. To me it is a big flaw to have the car stop itself when reversing when there is no reason for it other than a sensor or software glitch. In addition to being startling for the drive and passengers, it can cause injury. One time my non-BMW car stopped itself when I was reversing at around 3mph because I was about to back into a trashcan. It did it's job in that respect, however the unexpected stop resulted in an injury to my hand from jarring into the steering wheel. In that sense at least the braking was warranted. But to have the auto braking when it is not warranted is quite concerning. Especially given that it seems it is not just far extreme situations that seem to cause it.

Someone earlier said it happens when they back out of their driveway and when I looked at his pictures I expected to see some huge sloped driveway. Instead it was a pretty normal looking driveway to me.

I feel your "pain" about it being jarring. Thought I hit something the first time it happened. I have tested it at the dealer after the genius call and can confirm it seems to have solved the problem. Yes it will just temporarily disable the sensors and camera so you can bypass the braking temporarily. I do like the feature for the most part and it has prevented some issues for me. It is overly sensitive but this is a perfect workaround on the rare instances when you need it turned off.
 
Today I thought I tried defeating this reversing problem by inactivating all intelligent selections with the "blue" button on the center of the dash. I checked and it would not allow me to uncheck the automatic reverse auto break.

I would appreciate if anyone here can find a way of disabling this auto stop with one button press and then enabling it agian.
Thanks!

My car does not have that feature. But if it did and it slammed on my brakes every time I back out of my driveway the car would be gone and I'd raise holy hell with the dealer to try to get them to help me out of it. That goes beyond unacceptable.

I did call my dealer and they advised me to back off the driveway at the same angle as I used to drive in. I did and it worked occasionally, but the angle had to be too obtuse.

Is there anything unique about your driveway that seems to trigger it, compared to other driveways? Do you encounter this issue with other driveways? Please remind us of the year and model car you have. Thanks.
 
The perfection, or even acceptable use, of current automated systems is still years away. I opted for NO automated driving assists on my 2018 540i. The other day a new Kia Sorento almost side-swiped me changing lanes as I was driving alongside it. I could see the blind spot warning indicator in his mirror. These systems do not guarantee a driver will even look at them and heed their warnings. In fact, after using them for a while, I don’t think drivers actually “see” the warning lights.

Mark, my car does have all the available safety features including night vision. I find them to generally work quite well, not perfect but they do help. The side collision warning (not just blind spot detection) has helped to avoid the scenario you described but they are most certainly not a substitute for being a safe driver who is aware of surroundings, merely an aide. I do wish the BSM symbol was larger and in a better location on the mirror like on my former A6.

Very good points Mark. They are simply another tool. I also worry about people who only use those tools. They need to turn their heads and look. A blind side warning will not pick up a car two lanes over who is just starting to move over into the lane next to you for instance.

The problem is that the sensor is mounted way too low on the 2018 530e. I didn't have this problem with my previous car a 2015 535i, it would only beep once. Even with the auto-stop deactivated, the 530e goes crazy with all kinds of lights and beeps every time.

Due to this problem I deactivate the auto-stop. My driveway is pretty shallow where it ends on a street, so I know it will do the same on all others and that is NOT a nice stop, it jolts to an immediate stop.

Mark, on the 2015 535i the light was larger and on the post between the car and the mirror catching the attention of the driver immediately. On my 2018 530e, they moved the light to the outside corner of the large mirror and the light appears to be smaller. Bad move!

When reading this thread and others here (such as the A/C issues, false low tire pressure warnings etc etc) seems like lots of misc bugs and oddities. More as reported here: https://www.edmunds.com/bmw/5-serie...2018/long-term-road-test/2018-bmw-540i-xdrive-monthly-update-for-june-2018.html . Hopefully they got these things straightened out a bit in the 2019 models.
Keep in mind that BMW drivers in general, and even more so those that post here, have very high standards for their cars.

To wit, there was a multi-page thread about that little storage compartment in the dash by the drivers knee not being felt lined at first (it is now).
