Can anyone tell what might be wrong? These lights come on all together and go away by them self. Sometimes the brake lights will go away and check engine will stay. Then everything goes away after some driving.

Do you have a code scanner to scan for faults? It's a problem but determining the fault code is the first step.

Please update this thread later with fault code information to help the community. Good luck!

It could be a low battery. When it's low the power management system may perform a triage, diverting power to where it's needed most. That can cause some systems to be inoperable, which would cause warnings. Once a high drain operation has been completed, and starting the car is the highest drain operation there is, the battery charge level would come back up and power would be restored to those systems, and the warnings would go away. This might not be the cause of the OPs symptoms, but it's a possibility. One of these will tell you if you've got a battery problem, at a very low cost:

I ordered a scanner, hopefully that will help me check the battery also. Thanks for the insight. I'll update once I find the codes and/or problem and solution.

[yogi2472]

The codes I have are the following. P15B9, P152B, P15DB. Any help with these would be appreciated.

Google them, you should then find posts by others who've dealt with the same problem. Narrow the searches down by adding BMW, so you'd search BMW P15B9 and so forth.

I've seen these exact lights twice on two cars... both cars had a code for a vehicle speed sensor...

i can scan your car for free using iSTA if you're closer to northside of chicago

Thanks, that's what I found from googling a little bit. I just don't know which wheel sensor it might be.

I might take you up on that if I can't figure it out on my own. Thank You for the help! I'll PM you if I need help diagnosing it.

I got a scanner for BMWs, the Foxwell (Schwaben) NT510. The reader found the front right wheel speed sensor (ABS Sensor) was bad. After i replaced it all the codes went away. Thanks for all the input.
