ABS, brake light, circle with triangle and more

[Hebrewdiver]

I have all these lights on my dash. I have changed all the abs speed sensors, new blembo pads and Zimmerman rotors, and brake wear sensors because I was told this was needed. Turns out rotors were worn but not bad, pads were worn but not enough to set off sensors. I’m going to hook up to Ista+ and see if I can clear all these lights. Any help or suggestions would be greatly appreciated. Tire pressure light on even though I have added air to 35 psi. Air bag light came on after gf sat in passenger seat…lol I have a few other questions but will post another tomorrow thanks

What codes have you got?

Out of interest how old is your battery. Failing batteries can set off all manner of codes. If battery is not that old you could try disconnecting it for saying 30 minutes then reconnect and clear codes.

Haven’t put on a code reader yet but will do so today and post results

Battery is about 3 months old and I did disconnect for about 15 minutes with no results light still on. I’ll hookup to scanner osb2 and clear codes today

Dashboard lights will not clear unless you cancel out the codes.

Hooked up osb2 scanner and didn’t pull any codes. Any one have the comm port to hook cable to with Ista+ on laptop? I can’t get it to read? Mine was on com4.

I hooked it up to a OSB2 scanner and got no codes and having trouble getting my ISTA+ software to work. I think it’s not communicating between the car and the computer so could be the cable. I also saw on another post that it could be something called the yaw sensor

Yaw sensor doesn’t usually put the tyre pressure light on, just the other three.
So do a reset on the tyre pressure and see if that one goes away.

I removed the driver side rear wheel and found a wire that had been repaired had come completely a loose, the wire ran from the bottom of the box housing the abs speed sensor a small two wire cable. After reconnecting the tire light but the others remained. Gonna try to get ista to work to clear lights.

If it was the wire to the abs sensor then you may find a drive of a mile or two will reset everything.

Thanks Enuff more than enough. I spend so much time trying to get ista+ working to reset errors when all I needed to do was give it a drive of 100 feet and all light are off except the airbag light...but that's for another day. Zed i gotta thank you and the others that helped me diagnose this problem you guys are a lot more help than the shop that told me I needed new brakes and rotors which I didn't, abs speed sensors which I didn't. brake pads sensors which I didn't but replaced all anyway. So now I'm kind of hesitant about changing the front struts which they told me I needed. Well all in all a job completed with the help and guidance of all.

Good to know you've got most of the issues fixed.

I don't think I'd keep replacing bits, I'd try to find a good BMW Specialist first!

I think you may be Stateside which is a shame as most of us on here are in the UK and could have given some recommendations for good BMW Specialists.
