The G01 like all bmws since the E46 maybe earlier will flash the brake lights if there is hard deceleration. However, hard deceleration often means ABS being activated. So this function will almost never be activated in real life.
Research shows that activating the flashing brake lights earlier reduces the incident of being rear ended. I changed a couple of parameters in BDC with esys so that now it activates at any speed over 5km/h AND the deceleration is equal to or higher than 0.7G. The original values were werte 32 = 50 km/h and werte 0E for the 2nd line = 14 in dec = 1.4G deceleration. 0.7G is a firm to hard press of the brake pedal. You can adjust to your liking. The attached picture shows 1 is the speed above which it activates and 2 is the deceleration in G. I have mine at 5km. 05 hex = 5 dec = 5km/h 07 hex = 7 dec = 0.7G So if you want higher or lower just convert the number you want into Hex and put that into the werte. I did this already to my F30 and has saved my ass a number of times. The code is in BDC, 3075, and as below. |

If you want to avoid coding, you might be able to install an inexpensive part that flashes the brake light.
For example: https://www.amazon.com/Vehicle-Flash.../dp/B00FADDOL4 Installation videos: https://www.youtube.com/results?sear...se+brake+light However, I don't know how that product would work in conjunction with the BMW's brake pulsing feature under hard deceleration. |

My car has 552 from the factory. The attachment shows the settings that change when I remove 552 from my car. Scrutinize settings like BL_* (brake lights), FRA_H_* (rear indicator lights), NSL_* (rear fog lights), and RFS_* (reverse lights). If your rear indicator lights have separate bulbs from the rear lights and brake lights, you may also need to disable LIC_FEATURE_14.
What I just wrote is my first impression based on my review of the settings. I am not saying that I identified all the settings that pertain to the rear light assemblies. |

I am trying to figure out how to code the brake lights to flash on a US model (it's standard on non-US models). If BimmerCode already has the feature, I don't want to be reinventing the wheel. |
