ABS warning lights for newbie

Delisic · 05-22-2017, 12:54 PM

I like to share my lesson learned from my ABS warning light issues with other new 1Addicts.

I was driving around in my 135i enjoying the ride and bam my dash board light up like charismas tree! My first reaction was OMG..... F$%#!!!!
Well after freaking out for a while I drove back home and I started googling about ABS/BMW. There were some useful leads and then I found what I was looking for. So here is what I like to share with all the addicts if you are having issue with your ABS and your dash board is light up like a charismas tree with "ABS, Brakes, service engine soon light".

First, get your code reader and find out what side ABS is having issue. (Hopefully just one side) My 135i with 63K miles had a code P15C8 (rear left open circuit) your "wheel speed sensor" for normal people. I went in to RealOEM.com and found my part number 34526870077 (rear left or right speed sensor) and ordered it through BMW parts department. While waiting for the new part, I took out the old sensor and cleaned it to see if this will make the warning lights disappear. Cleaning the sensor does not do anything to help make the warning lights disappear.

After receiving my new sensor from BMW parts, it took me about 30Min to put the new part on and as soon as I started driving my 135i the ABS, Brake, DTC warning lights disappeared!!! However, my service engine soon light still was on my dash board. I was deflated again but after driving around for mile or so the service light also vanished. Victory!!!! Hope this experience helps other 1Addicts who has problem with your ABS/DTC sensors!

I received great advise from WDE82 an 1Addicts member who just told me to buy a new OEM sensor and do not buy anything but OEM or genuine BMW part. thanks WDE82!!

Good to hear. I recommend you go to your original thread and put this post there so anyone who comes across that thread knows how the problem was solved.

^^^ Agreed. Good job on troubleshooting your own issue, you definitely saved some cash there.

Stewy_604, thanks....
You are so right, I so did save a lot of cash! I think it would have cost me over $400 if I took it to a BMW mechanic. I really do enjoy working on the BMW, what a ride 135I is. The car just puts smile on my face when I get near it. lol
