Light show on dashboard

Synergy · 01-16-2013, 11:50 AM

I was driving my 328i and out of nowhere, all these lights show up on my dash (my SES was already on for an EVAP leak). Has anybody had any similar symptoms on their 3 series?

Car has 73k miles, no recent mods. The only thing that has "changed" recently was a bottle of Techron with a full tank of gas, but I use it all the time and have never had issues.

Check your battery. Sometime low batteries can cause these errors I v seen here in the posts. Keep us posted.

I do have a decent aftermarket sound system. JL 500/1 and JL 300/4. It's very possible this is the case. Thanks for your input! I'll take a look and let you guys know.

Wheel speed sensor.

Where's that located? Does it usually go bad? My TPMS light came on the other day and said "inactive", but it went back to normal after a while.

Thanks for your help!

Wheel speed sensor 100%, had 2 go on mine (100k miles now). Can come and go intermittently. There are 4 of them located in each wheelarch. You need to hook it up to diagnostics via the obd to tell you which sensor has gone.Each wheel has one located in the wheel arch next to the brake sensor. Traction control cuts in like its mis-firing and then the comp realizes there's an error and shuts the whole system down, including the abs. Driveable but be careful in wet weather.

Thanks for the info! I'm going to have the car scanned this Saturday. I appreciate the help!

I had the car scanned for errors and this was the only error the showed up. Shouldn't I be seeing some sort of ABS or DSC error? I did have a check engine light for a EVAP leak (p0456) a while ago, which I cleared (and it never came back). This sounds like an EVAP leak still. Odd

up! can anyone help?

Synergy · 02-03-2013, 07:23 PM

just replaced my battery and the issue is still present. i did notice that now my blinker doesn't reset after i turn the wheel. is this a bad steering angle sensor? it wasn't doing this before i replaced the battery

e90pilot · 02-03-2013, 07:33 PM

Yup that is a steering angle sensor.

Had same issues, brake light would flash red and yellow, traction control light, DSC, yellow exclamation, abs, speedometer would cut in and out, a bunch of other lights I couldn't remember. Took it in to my Indy and basically what was happening was that the alternator was showing 12, 14, even 16 volts while running. I ddnt think it could have been the alternator since I just had it replaced a little over a year ago but long story short after it was replaced no more lights flashing on my dash like a Xmas tree. I'm jus glad it wasn't the cable to the fuse box that some ppl were having to replace. Got rid of my rough idle too, stays exactly at 600 rpms now.
