Yellow Brake, Tire Pressure and DSC Lights appeared in dash
Hi everyone,
The brake, tire pressure and DSC lights turned on all together today. It didnt show up when i started the car but it showed up after i pulled out of my neighborhood. It was the first time driving the car today. The last time i drove it was last night. What should I do? It doesnt affect the drivability of the car. Im just worried that if i keep driving with those 3 lights on, i can potentially cause futher damage... Thanks |

I’d suspect a failing alternator.
I had this happen last year. What turned out to be voltage spikes and drops was giving me ABS, Brake, and DSC lights, along with infotainment system interruptions. Local Indy shop confirmed the diagnosis by monitoring voltage real-time while driving. Mine got progressively more frequent over a few weeks as the alternator got worse. |

I had same case after winter storage battery charger, that's my guess. code 005DD2.
Was trying to fix by DIS, SSS, INPA with no luck. Today I finally was able to recalibrate DSC unit and get rid error with INSTA+ |

It probably just the voltage regulator on the alternator. Common problem with the Z4M. Somebody on here was able to find the part is available separately from the alternator on ebay. I picked one changed it and the warning lights were gone.

Mine went off about the same time yours did. I had a local shop clear the codes Wednesday. The lights stayed off for about 20 miles; came back on. Cleared when I restarted the car, went another 10 miles home, and lights were back on. Yesterday, started, no lights. Drove about 100 miles, lights back on. after two more cycles, lights are now on and will stay on until I clear codes again. No change in feel or performance after lights returned; manual specifically states it's OK and not dangerous to have lights solid yellow.
Had front control arms/bushings replaced about the same time, and got new tires a week ago. I'm tempted to pull the negative battery cable for 15 minutes and see if the lights go away. Good luck. |
