Error messages galore. What is wrong?

Denny347 · 05-11-2014, 06:32 PM

Was driving home and suddenly I get a crap ton of error messages. These:

I got these ALL at the some time. Not sure how they are all connected to the same bad sensor. I ran my BT Cable for codes and got this:

Would just a steering sensor do all of this?

Yes a sensor will set off many lights as I had a bad wheel sensor and that set off abs dcs and self start assist.

Hmmm, wheel sensor huh? That would be better than a steering angle sensor. Ahh, but my turn signal does not turn off after I turn so it maybe the steering sensor. But how does that affect my DSC and tire pressure? They all came on EXACTLY at the same time and I did not hit anything nor had any work done.

DSC needs to know the steering angle and wheel speeds to work. All the other systems rely on information from the DSC so if it is not functioning then the others won't.

Usually its a bad wheel speed sensor or bad steering angle sensor that will trip all of these lights at the same time.

Ha-it's my work computer. Too funny.

I'm going to pull the steering angle sensor and clean it, maybe that will work. This is the correct sensor if I need to replace it? http://www.ecstuning.com/Search/Site...ngle/ES260287/

Not tire pressure. It's a Flat Tire Monitor (Not TPMS). According to manual:

"Flat Tire Monitor detects pressure loss in a tire by comparing the rotating speeds of the individual tires while moving. In the event of pressure loss, the rolling circumference changes and, thus, the rotating speed of the affected wheel. This change is detected and is reported as a flat tire."

So, it still points to a malfunctioning sensor, possibly in the wheel.

Yeah, that's what I meant to say. My BT didn't give me a particular wheel sensor to check.

Ok, follow-up. Spent an hour or so following this procedure http://www.e90post.com/forums/showthread.php?t=520467

I pulled the steering column apart (it was really easy in fact) and pulled the Steering Angle Sensor out. Took it apart, the disc looked rather clean but I polished it with plastic polish anyway. Put it all back together and BAM...ALL the errors went away. Well, except for the airbag

. Then it dawned on me I forgot to connect the small black plug on the rear of the steering sensor. Pulled it back apart real quick, plugged it it, and done. Connected it the car to my BT tool and erased the airbag fault. After driving it around the block, I rescanned it and not a single fault was found...and it didn't cost me a penny. I like that. Hopefully the fix lasts.

A bad ABS ring sensor would do that.

What a coincidence lol
Just picked up my car from the dealer and on my way home I got the exact same issues minus the TPMS.
Mine is a 2011 335is
Guess I will be driving it back to the dealer next week
