Weird, Weird and more Weird "warning lights"

Brandon002 · #1 01-31-2014, 06:12 PM

So this morning I get in the X to drive the little one to school. I pull out of the driveway and the "Brake" light on the dash illuminates amber. I pull in to the school and while sitting at idle the "trans failsafe prog" warning comes on. I shut off and restart the car a few times and the issue stays.

Walk her in to school, come out, start the car and the trans failsafe and brake lights are still on, I pull off and drive about 50', both warnings turned off and the car has driven perfectly fine since.

I have read a faulty brake switch can cause this, the one that is tripped by the brake pedal. No fault codes stored either.

Check your voltage? faulty alternator can cause some of these problems

Voltage is fine, I replaced the alternator about a month ago. Battery was also replaced. That was the first thing I tested when this happened, pulled up the voltage on the OBC.

Blame it on the Polar Vortex, have lights coming on my X ever since we got hit with this Polar Vortex. Us my scanners to read the DTC and clear them and some new one will pop up later.

I've been blaming everything on the polar vortex already.

Just figured I'd ask. ha ha.

BTW, where in Illinois are you? I need someone with INPA to help me calibrate my suspension. My buddy had it, but his lap top took a crap. I'll buy beer, or pizza or whatever.

Crook County, She-ca-go, South Loop.

Don't have Inpa, I have Carsoft 6.5, BMW Scanner 1.4 and Torque.

ah, damn. I thought I read a post where you had the other software.

if you had trans failsafe, there must be a code stored in EGS... did you read that module? i think something was not "plausible", as BMW likes to say... one of the sensors "fell offline"... could be a fluke, due to vortex, could be something else...

what did you use to pull the codes?

Used an OBD scanner with a trans scanner feature. No codes showed for engine or trans when scanned. Hoping my buddy gets his lap top fixed so I can head to his house this weekend to calibrate my suspension and give a full scan with actual diagnostic software.

Chi-town is expected to receive 6-9 inches of new snow. Even though it's AWD I still hate driving in that type of weather. Not because I don't trust my driving skill, but because I don't trust the idiots next to me.
