Intermittent Multiple warning lights BCM
Hi, I'm getting the below warning lights intermittently (photos attached), around 60% of the driving time they are on. I connected a couple of code readers, I deleted these warnings but they come back, also there are no other faults.
I believe the BCM needs to be cleaned or reprogrammed. Is this something I should try to do myself? any manual how to do this? or do you have any other ideas? I'd appreciate any help. thanks.

Do these warnings appear as soon as you start up and when you have cleared them, come back immediately?
Or do they only come back when you have driven a few kms? How old is the battery? (An old battery can cause random warnings) |

Thanks for the reply IJO,
The lights come back after I have driven a few Kms. They disappear after while continue driving then they come back. :@ The battery is pretty new. |

One of the ABS sensors may be intermittent but can't be sure without the codes. Affordable scanners are: Ancel BM500, BM700 (Amazon) and Foxwell NT 530 For s Smartphone, checkout BimmerLink Otherwise it gets complicated if you want to use a laptop. |

check error memory with bmw oem diagnostic software , may check all radar sensors ( front sides and rear sides) for correct placement and fitment into their brackets... ( bumpers needs to be removed to do that properly),
