- You have the BAS/ESP light on and a system diagnosis points to the Yaw, Turn Rate sensor. Car may brake automatically and dangerously. Your car is NOT ROADWORTHY. Attend to this IMMEDIATELY to avoid accidents.
I had first hand experience with this problem and i was lucky that i survived it on a bridge as the car behind me was about 100m away and saw my wheels smoking allover when the erratic breaking kicked in at 72mph. A day i will never forget and just warn anybody never to take chances with this issue!
I had this problem for 6 months an I found yo video yesterday an done it thanks brother. I was scared to drive it with my kids in the ml320 thanks alot for the info 💯
thanks! great you're safe
God bless you man. I've had this problem for more than 5 months now. Been to several workshops and nobody could fix it. Everybody wanted me to change my ABS module or pump which wasn't the case and it also did not work when I tried replacing some of the abs parts... I was so afraid to go on a highways because the car was randomly braking 2-3 times a day. The first time when I went to a workshop the worker there told me that the yaw sensor is OK and that's why I never thought of replacing it or just disconnecting it... I disconnected it a few days ago and the car is running normaly again... just the ESP warning is on the dashboard and at this point I can't care less. :)
Awesome. Glad you got it fixed.
I had this problem several years ago with my 2001 ML. $1200. at the dealer for repair. They charged me way too much but fixed the problem.
I changed my yaw rate sensor so far so good thanks to you, god bless you
great job. stay safe
Hi did you need to reset with scan tool. Thx
I changed my yaw sensor early today watching your video and it worked like a charm thanks.
cluthr o great job. Stay safe!
You can just disconnect this yaw sensor. The BAS/ESP light will come off anyway, but it won't brake by itself anymore. The ESP and BAS systems still work, but the yaw part of the ESP will not work, off course. Pay attention in roundabouts, hard turns and entering water sheets with just the right (or left) wheels.
Did you turn it off on a diagnosis machine or just unpluged the sensor ?
I didn't understand, the light will be turn off or on, after disconnecting the sensor ?
I want to try to disconnect because I'm with some difficulties in buying a new sensor, no one have them to sale...
Thanks!
Thanks man, I replaced it now it’s working well appreciated.
Thanks, glad it helped...
Great video, I preach safety and the benefits of preventative maintenance as well brotha, keep up the good work ! 👌🏻💪🏻
Omg this helps this just happen to me and my daughter driving we are traumatized ( literally five minutes ago)
thank your surport community.
Always
You are good man , god love you , you are the best
Thanks you Kent for this great video. After replacing to a new Yaw rate sensor - do you need to clear the codes with a diagnostic machine?
You’re the man!
I have 2001 Mercedes ml 320, I have similar problem with your car braking itself, this sensor will solved my problem?
agner duque sorry for very later reply. Replace the sensor after reading the codes, it will definitely solve your braking issue
txs a lot man
You're welcome!
mi Mercedes ML 320 año 2001 le ocurre una falla que no acelera en ciertos momentos y requiere apagar el motor y volver a encender apeas que continue la marcha. cual es la falla?
Dear Sir, i have a similar problem, the bas light is onand once in a while the car brakes for a fraction of a second, but it seems to brake on one side, which is quite dangerous.
Can this be the abs wheel sensor or the yaw box?
Thanks in advance

I'm sorry for not replying. A scan may help toi identify this. I hope you got htis fixed
Hi Kent...thank you very much for your information...Could you let me know which wheel got stuck first when this problem started? Best regards from Brazil!!!
Oh so sorry. I must have missed this comment. If its still relevant; i f memory serves me well, must have been the rear left wheel.
I had the same problem on my 2001ML. It would randomly brake. going straight down the road. Whenever it felt like it. So I disconnected the relay for the ABS, and eventually I'll get a new sensor. I have a used one, but I'm not sure if it's the same part number. And taking that console apart is tricky, maybe I'll attempt it one day
CORVAIRWILD lol, ok, all good. Just open the console carefully, you will still have abs working,its better than disabling it altogether
Kent Noetico I'll post a video, I have several thousand. I'll report back with results. I did post a short vid of BAS acting up 2 weeks ago, just got lucky and was able record the incident
CORVAIRWILD Have you taken a scan of the car ever? Use a scanner that can read the traction and and abs systems. Get the codes and lets know what you get
Kent Noetico codes were RR abs sensor, a friend is sending a used one. As well codes 137 and 147, or was it 127 and 137? The tech asked if the trans is slipping, it is most certainly not!
Mercedes "737 MAX MCAS" design, this can kill.
Okay, if I’m going to change yaw rate sensor will solve my problem being braking itself?
My rotational rate sensor it's done it's not working so I have to take it out so that I can get the new one
I think its the same sensor as VW, AUDI and SKODA use, brand ATE but other part numbers, but they look absolutely same.. its the totally shit sensor!! few years ago i had this symptoms, so i changed this sensor and now after few years this fault came again.. ESP suddenly again brakes my wheels.. the sensor is gone too, ATE company should be punished for making so dangerous sensors!!!!
Kent, just chatted today with you on Benzworld forums Sir. Just found your video here, I see you're the 'expert' at this issue. I will pull Yaw sensor after scanning. As a quick 'safety fix' may I just pull the ABS relay (either K25 or 27 can't recall which) to prevent this dangerous sudden braking issue ? Many thanks - David ['E 320 White Wagon']
David A Hi! I will confirm this for you. It will certainly disable your abs which means you will need to avoid high risk braking so you don't skip. Abs light will illuminate.
David A ok looking at fuse assignments, that may not be very good as f25 is protecting several other circuits, f25 and 27 protect the traction system so this may not be good. You will loose some crucial lights, potentially your instrument cluster. So best thing is once you confirm it, before a replacement arrives, remove it. I can always assist with getting to the sensor...
@@kentnoetico9867
Ok Kent thanks for the quick reply ! I just removed Relay K25 "ABS-Hydraulic" from under hood fuse relay box.
Yes, now I get all 3 lights on left side, BAS+ESP, ETS & ABS, but I believe (pls confirm if u can) that the ESP induced automatic braking should NOT occur, scaring me to death or causing accident.
The only reason I'm doing this 'pull K25 relay' is to give me time to search Ebay for a used Yaw Sensor & have time to install.
I will study your video & others to see how to pull console, hopefully without breakage, LOL !
PS: instrument cluster still lit...
My car 2001 ML have same problem, braking and BAS/ESP light on. After replace yaw sensor need to calibrate with the Star diagnostic? Need I replace lateral acceleration sensor, or only yaw sensor enough? Thank you.
Suren Badalyan you should replace just the yaw sensor. That will be fine
Kent Noetico Thanks friend!
Kent Noetico Dear friend, thank you for your support. I changed yaw sensor in my ML 320 and problem with braking solved. I read before change the error code, it is C1120 (ESP yaw rate sensor B24/15). I clear error code after change sensor. Thank you.
Does this have anything to do with the VSA LIGHT BEING ON?? CAUAE THTS WHTS HAPPENING WITH MY TRUCK ANS MY TRUCK JUST BRAKE WHILE IM DRIVING DOWN THW ROAD?
Just had this same automatic braking problem at 70mph on the dual carriage way - probably the most scary thing that has ever happened to me when driving! I have for the moment disconnected this sensor - will that disable this behaviour until I can order and fit a new one? Also does anyone have the part number for the replacement sensor? Many thanks
Sure you should unplug it, you will have the BAS/ESP light on but the braking problem will be gone. I will look up the part number for you.
@@kentnoetico9867 Awesome - thanks Kent for confirming. From stop framing your video the part you have there is A 003 542 23 18 which seems to come up as Mercedes-Benz Yaw Rate sensor
Just to update - disconnected the sensor on my ML55 AMG last night after the ABS kicking in during driving previously. Did a few local tests last night and then drove 250miles today no problems at all (bar the BAS/ESP light being on) :-)
Help me out bro.if i take it out is still driveable.because mine is right front brake only braking?thanks.
Sure! You can drive the car, safer than having it braking erratically. It’s been years, haven’t replaced because haven’t been able to import the original part.
@@kentnoetico9867 thanks for answering.now i can take out my ear plugs or turn the music down.appreciate you bro.again thanks.
Thanks a lot! Enjoy
Thanks
ABS not BAS???
Do you know if the yaw sensor is located in the same place on a 2002 C320 ?
deb giam I can check it up for you. Kindly look out for my reply.
I have a 2001 c 200 cdi and i had the same issue, and mine was located in the trank behind the rear seats
Hey if disconnect the sensor will this problem be solved?
Yes please, it will be solved.. perfectly.
How to find the esp sensor on Mercedes 2001 mL 430?
Guillermo Castaneda same place as shown in the video, under the center console
Again after braking itself light comes on BAS/ESP
scan the car, but keep in mind that the light willbe permanently on, this is nothing compared to the danger of braking on its own. i have no issues all these months. just ignore the light, once in a while you scan to see if there are any other additional issues in that system
Does this have anything to do with ur VSA LIGHT
have u scanned the car?
my piece of garbage ml decided with no warning lights at all no esp bas nothing to just completely lock up the right front wheel at 40mph ,luckily i wasnt going fast that time . Disgrace design by mercedes these sensors should be 3 times redundant i cant imagine this happening to a toyota its just german things all the time a small sensor or some other terribly engineered equipment. I removed the abs relay and plan on using until something major fails .after its going straight to scrapyard people wont pay more than 1000$ for this trashcan even in perfect condition and now i understand why
Haha, that thing is scary. I still use this particular ML and have never put back this sensor. After all these years I think its almost unnecessary really in the first place. The car is reliable if handled properly, I hardly have issues and I don't allow guess work on the car. Any way. Unplug the sensor, your abs should work, that's better than disabling the abs completely
@@kentnoetico9867 how many warning lights are on with sensor disconected? because with 3 on the left related to abs its frikin blinding at night
