ABS unavailable Mercedes
Remember, even though you're getting the abs currently unavailable Mercedes light, the repair steps we show you here on this Mercedes (W204) C250, will still apply if you have an abs unavailable ford or if your abs check engine light stays on with other brands of cars like Toyota, Ford, Honda, etc. Once your abs check engine light turns on and stays on, you need to get an OBDII reader scan tool to plug into your OBDII connector under your driver's side dashboard and read out the check engine light codes. The scanner talks to your car's computer ECU and reads out the check engine fault codes that set off the check engine light to begin with.
C0034 engine code
Once you read out the code the abs light fix is as simple as determining what the engine fault code is telling us. In this video the C0034 engine code simply means that the front right ABS wheel speed sensor is out. This is a sensor that plugs onto the inside hub of the wheel, supplying wheel speed to the car's computer. When this ABS brakes sensor fails, the system cannot figure out how to best apply the ABS brakes, so it turns on the abs check engine light, and gives up, saying that ABS is unavailable. Now you have to fix the error message and clear that C0034 code root cause for good.
ABS currently unavailable Mercedes
You can also get the condition where your ABS light stays on Toyota Camry models, and you can get abs light stays on Honda accord vehicles as well.

No one
Thanks a lot! This is really helpful!😊
Thank you as the steering wheel trick worked for me. I still need to get it checked & hopefully not going to be expensive
This video is SO HELPFUL. I own a 2006 E55 AMG and had this same issue today (Saturday 06/27/20) and started researching and came across this video and relief came over me....
Glad to help out Robert, hope this helps your repair.
DEAR MR MB DOC! THIS IS THE BEST DO IT YOURSELF MB REPAIR VIDEO EVER! THE WORLD CLASS TUTORING!!! AND GREAT LOOKING ACTOR AS WELL!
Man you have done exactly what came on last night, unreal, I have excellent tools and do my own stuff but this will be new, thank you
Great to hear! Let us know if it works out for you OK Mario
Nice one!! the steering wheel fully to the left and fully to the right worked for me in my Mercedes Sprinter 314. Thanks bud.
I rotated my steering wheel from left to right all the way back and forth, standing still, and then while making turns AND IT FIXED MY CAR!!!!! can’t tell you how excited I was thank you thank you thank you
Thanks for sharing
I just did it as well and it worked. Thank you soooo much.
Thank you very much for a extremely helpful video. I was able to order the part and easily install the new sensor. Error message went off immediately. You saved me over $500 to repair this faulty sensor without bringing it to the dealership.
Yeah, that's how it's done!
Four hours! Holy cow! I did mine in about 45 minutes. As you say, a scan too is essential. I have an iCarsoft MB II and an iCarsoft MB V3.0 for both of my Mercedes. The usually fit in one of the storage compartments of the car. For a few more bucks, the MB V3.0 is a better deal. Much faster and more features than the MB II.
Thank you for this amazing video. It helps a lot to calm down the stress caused by the dashboard error message.
Awesome, glad to help out, and thanks for watching Israel!
I definitely felt the stress as I was on the motorway & the car was driving funny. Once again, thanks
You're a lifesaver man, had both my wheel speed sensors go bad in a week now im just hoping my rear ones don't go anytime soon :(
Yes, it's really strange that they often both go at the same time
Awesome video!! My 2013 4matic C300 did not have the two wires at the speed sensor/firewall connector but just the one... this video saved me hassle and $$$!! $60 for Genuine MB part and 2 hours of labor.. Also, all the warning lights were still on after replacing the sensor but as soon as I put car in motion (drove car) the sensor sent proper signal to computer and lights went off!! No reset or anything needed as you mentioned.. thanks again!
Yes, that's exactly how it worked for us too
Super job, great presentation- unbelievable results saved tons of $$$
Thank you, and continue to create super training diy vids
Thank you very much for your great video. I was able to fix myself my 2017 slc300.
Thanks for posting this great video. I'm in the U.K. but it works exactly the same for my right hand drive C250.... 👍👍
What a great video!!! I was able to resolve the issue with our 2010 GLK350 by turning the wheel lock to lock. If the issue returns I will definitely purchase the speed sensors via your video.
Way to go Mark!
Thank you for this clear and concise instructional video. Now I have to go to work on my R172.
Glad it helped Let us know if it worked out OK for you.
Glad to hear it you liked it. Let us know if it works out ok for you.
Just done the "turn the wheel in both directions" fix and it worked on my 2013 W221 - Thanks for the tip.
Glad it helped, We are never so lucky! We had to replace both ABS sensors. would not be surprised if the issue is intermittent and returns.
You’re right! Problem came back the following day, it’s been diagnosed as front right wheel sensor.
I tired it doesn't work for me. I pray it would as to I'm headed out of town
Excellent video. Thank you, thank you, thank you. You've saved me a lot of money. 👍
Very wonderful presentation and very helpful video. Thank You
Glad it was helpful!
Excellent video! Took care of my problem. Thank you!
Glad it helped!
You Rể the best easy to understand and clearly …👏🏼👏🏼👍👍💖
Amazing video. Will get a scan tool to identify which sensors need replacing. Subscribed and liked!!
Awesome, thank you!
Thank-you, excellent video nice clear camera angles and very informative. You have given me the confidence to tackle my faulty front right sensor. Note : The fault cleared by turning the wheel full lock both ways a few weeks ago but has returned! I'll also get the Milwaukee impact ratchet too.
If the problem returned, then it might mean it's time to replace the sensor, and not just try to clear it. We have found with the ABS sensors that it's also best to change left side and right side when you do it.
Great vid. Very informative and concise.
Glad you enjoyed it Jenna!
Great video Jeff. Thanks for thingakings the time to make and share thos video.
Any time
AWESOME VIDEO....THANK YOU SO MUCH....HAD THE SAME PROBLEM ON MY 2009 GL320....
Glad t help you solve it Dorky!
THANKS so so MUCH. I didn't realize it was an ABS sensor.
No problem 👍
Hey I just wanted to say thanks. Turning the steering wheel left and right, fixed the problem. You guys saved me so much money and head ache, thank you so much, keep up the great work.
Glad it helped! Did the fix hold, or did the error come back?
I hope this helps me 😩😩
@@carbuying do u have a email?
@@carbuyingmine came back sadly, looks like it pops up when I hit a bump ..
Excellent!! You are the Only one who removed the electrical part correctly....PUSH DOWN....
Mercedes-benz way
At the beginning I thought this would be a generic how to. I was pleasantly pleased with the simple guide to doing a job that would send most scuttling to main dealer to get job done. I think my 80 year old neighbour Janet would try this repair after seeing your instruction
Thank you Barabara!
Nice detailed video! Thanks.
Glad it was helpful! thanks for watching Juan Carlos
Great info, Thank you, From Malaysia
Our pleasure!
Thank you Thank you Thank you Thank you !! You just saved me a trip to the dealer where they probably would charge me the cost of the car to fix it!
You are welcome!
Great video thank you
Wow, that’s totally awesome, thanks
I really like the way that you explain all perfect voice control and professional, I have a c300 and that just happened to me the light came on but I open the globe compartment and turn all the weels and came off and happened before I wacht the video. Any way ty,
From Dominican republic
Glad I could help!
You should ALWAYS use jack stands when working on a raised car. Those flimsy crank jacks can fail and crush whenever is under the car. If you don't have a jack stand, you shouldn't be working on your car. At the very least, put the removed wheel under the car just in case the car falls.
Well done!
Ultimate video was very helpful for me
Glad to hear that
Great information organization !
Glad it was helpful!
Very informative
Ok I didn’t get any information on driving the car when the auxiliary malfunction sign is on what can happen or how long you can drive it like that it an ML 350 2015
Great content. I'm gonna try this on my wife's car.
Good luck!
Awesome video!
Glad you enjoyed it
thank you ...its worked with me turning the wheels right and left all the way...the signs showed up after leaving the car on in the parking with 60c temperature 🤦♂️
great one
Very good video
Thanks for the visit, glad you like it Tonnie!
Great video! My car has the same problem and is in the shop to replace the sensors. Just curious, what is that little coffee cup indicator near the "P" in 18:10 on your dash?
That coffee cup alert comes on when you've been on the highway for about an hour, and bugs the heck out of you every 20 minutes or so with 4 loud beeps to get your attention to prevent highway hypnosis, and it reminds to stay alert, I.e., like a cup of coffee.
I had this problem with the right rear sensor on my own W204. I replaced the sensor but it didn't fix the problem (most of the time is IS the sensor that is faulty). I had to replace the pickup ring which had delaminated. I had to separate the driveshaft from the hub assembly and I was able to replace the pickup ring without having to remove the driveshaft from the rear differential. The ESP and ABS light came back and I found some remants of the old pickup ring I didn't notice when I changed the ring and it has been fine ever since.
Got mine fixed last week as the fault kept on coming back every week.
It ended up being the wheel bearing and speed sensor that needed replacing.
Maybe you should take it to a specialist who has a computer to hook up to your OBD port.
Only cost me under £300 but was peace of mind I got it done
Hi there - love your vid. I have a question regarding an engine check light and icarsoft MBV3.0 I have just replaced both front wheel bearings on my W211 E200K 2007. I am getting a fault code " Front Right rpm sensor, GAP INVALID " on my icarsoft MB V3.0 scanner.💣
I believe that the comment Gap means that the oil seal that I used is not being read by the sensors - I purchase a seal from a very reliable bearing wholesaler who checked the oem part number of the seal to ensure it was a perfect fit into the hub - which it was. I have also been reading that unless you used a genuine Mercedes part it will bring up this error. I have not yet changed the sensors as they were functioning perfectly before I changed the bearings. Can you help with any advice about the seals and if you have ahad any problems using non mercedes seals? I am in Australia Cheerz and look forward to hearing from you soon. Regards Stuart.
Does the Genuine Mercedes-Benz RPM Sensor 204-905-29-05 work on the both front left and right side? Thank you!
Thank you so much. This is exactly what happened to my C250. You saved me $500 if I got the dealer to repair it.
way to go michael
@@carbuying My dealer is saying all 4 wheel sensors need replacing ? Surely not all 4 would go at once ?
Thanks for this video, my car has been having an issue the engine check has been on and lately, traction and stability control systems and the speedometer stop working and starts fluctuating and the car refuse to accelerate, really would need help someone said it's an abs issue, i just want to be sure, thanks
Great video, thanks for all this information, BTW the OBD II reader you are using in the video I could not read the manufacturer brand would kindly let me know which one is it. Thanks!

Same issue i had and the fault was my driver side front wheel i replaced it and code went off and i drove it and it came on again. So i hook the obd up again and now its my right front sensor now ?
طريقة الشرح ممتازة شكرا لك 😘
English?
carbuyingtipscom the way explained is very refined and easy way. thank you 😘
google translator is great to use :-)
Hello i had the same issue on my w204 2011 c220 cdi after chaneing right front sensor foult stays on do i nead to test drive it?
Hi, amazing video, easy to understand, however i woild like to know , What is the number of the wrench you used to remove the sensor screw?
That was the open end of a 10 mm wrench
Hi does that really take 6 hours, or are you accounting for someone doing this at home for the first time? Just wondering how many hours labour will be charged if I take it to a garage. Thnx
Having this exact problem right now with my Mercedes. Mine is a 2015 c250 coupe. Think I'm gonna need the exact sensor to fix it.
Luckily weather is cooler out now, we were dying in the heat filming this video
hello, the esp and traction lamps of my 2012 model c250 Amg remain on and the car does not move forward even though it is running.
I had this issue recently fixed. It was high voltage from the thermostat that needed to be changed. It was expensive unfortunately but the problem wouldn't go away.
Can you fix it yourself?
Great video! I just subscribed! Will this work for a 2007 Mercedes s550 base model? (Video on my page describing).
Yes it will if the codes read out the same
I have an 04 G Wagon AMG55, great car and I was always hesitant in buying a used Merc, but they are really easy to work on, I had this same problem with the ABS light coming on, I replaced the stop lamp switch and tried the steering wheel calibration but nothing would fix it. I was ready to take it to the dealer, the fault code still read stop lamp switch. Then I checked the brake lights, my third brake light was out, started checking the fuses and sure enough one 5 amp fuse was blown, I think the switch went bad and caused the fuse to blow which caused the ABS light to come on. Just an FYI guys. I got lucky!
Yes, that was one of the weird cases we mentioned, where a seemingly unrelated blown fuse was the culprit. Glad to here you solved it.
So the sensor caused the engine check might as well and the other 3?
Hi thank you for this video,
So i will be very happy if you can help to find a problem or just to be sur about the technical part (diagnostic) that show me a code linked to abs box's.
Im not sur, the problem is when i turn on the engine everything its Allright but when i start to drive juste a few meters the steering whell hard esp abs not available on the dashboard.
Please if you have solution share it.
Thank you again
You have to read out the engine failure code using an OBD2 reader, what codes did you get?
Is it safe to drive my car like this while the parts arrive?
THANK YOU !! You should teach other TH-camrs how to make videos.
You're welcome!
Hi, the link for "BAFX Wireless Bluetooth OBD2 Diagnostic Scanner & Reader Tool" says that "This OBD2 scanner does not read ABS, SRS, TPMS, Oil Change or any other non-OBDII related lights". Am I able to read the ABS fault code with this tool or any other simple OBD2 reader? Thanks!
Rodrigo, yes this does work, ours works, unless they changed it but doubtful. Yes, we just fixed another car Mercedes 2013 C250 W204 version with the same issue this week, read out both left and right wheel front fault codes. Once we changed both wheel ABS sensors, the alert lights all shut off on their own after driving about 100 feet. Don't panic when you start the car and the lights are still on, they will go back off after a bit of driving. No reset of any engine codes will be necessary luckily.
Hi,
Thank you for your video, helps a ton! Anyway, I just replaced right front wheel speed sensor on my 2012 c250 coupe (have the same code shown in video), but I’m still getting ABS inoperative message, I need to reset or drive more?
Thanks!
Did you try driving it a few miles, see how it does?
carbuyingtipscom Hello there! I seem to have the same problem on my 2013. I’ve driven the car for quite a few miles now. It turns on and off. Sometimes I have my abs available, other times I start the car and it’s on again. I also tried disconnecting the battery for a little to no avail. Any help would be greatly appreciated!
carbuyingtipscom I did drove the car a few days now, the ABS message comes on sometime and off other times.
@@carsandpassions9116 where did you buy your sensor from? Maybe the new ABS sensor is unreliable.
Hello first I really appreciate the information you give us, I have 2015 GLA 250 that has the ABS and all of the other lights on as well like in the video the reader said front right wheel speed sensor faulty I replaced the sensor checked all the fuses and I reset all the rights and after I drive the car for less then a 100’ the lights come back again and from the same sensor I checked the sensor and it does have voltage. Any advice what I need to do here please? I really appreciate your help!
Have you tried using an ODB2 reader to reset the code in the engine? It could be that that you car is not automatically resetting the code when the condition disappears, or maybe there is an electrical issue triggering this, like maybe a bad fuse somewhere. We have seen where one bad fuse unrelated to this can cause a false positive. You should also try Club Lexus Forums, and ask there, very knowledgeable people there, who might have seen this issue. Let us know what you find.
carbuyingtipscom yes I did reset all the codes and as soon as I drive it the lights will come back. Do you know where the sensor read the speed from?
Did you get a resolution for this? I have the same problem.
Good video very thorough, and helpful,my only criticism is there should be an axle stand placed under the vehicle where you are working, these car Jack's aren't designed for maintenance only for changing your wheel at the side of the road,other than that very watchable.
es, but most people don't have a jack stand
@@carbuying then put the wheel under the car just incase it falls.
Good video,I also thought of the same thing,actually mercedes Benz jack kit normally comes with a metal folding wheel chock
Hello, purchased the new sensor front rt. Changed it as you demonstrated and completed however the lights are still on, I have the icarsoft scanner and the alarm is the same you found, I bought the sensor from Parts Geek, I bought the correct one!! But looking at the old one it had numbers on it I couldn’t find on the Holstein part so I ordered a new on from Mercedes parts sight, it was 77.00 compared to the 37.00 Holstein part, any thing else it could be? I’m a big subscriber you have excellent videos thank you. Mario
Hi Mario, how far have you driven the car? With our other car, the 2013 Mercedes C250 last week, we had to replace both front sensors, and it took a few hundred feet down the road for lights to go away on their own. Maybe try to drive it for a day see if it goes away on it's own. Also might try resetting the error code, maybe the RT needs to reset it rather than going away automatically. Hopefully there was no problem in your wiring harness. Try exercising the steering wheel all the way left and all the way right, drive around the blocks a few times. Also dumb things to check, did you actually attach the new part after removing the old part? Sometimes we do odd things in the heat of summer. Let us know what you find.
Hello and thanks for checking on me, I installed the new correct part and all went off except check engine light, I hooked up the icarsoft scanner and it says the right front rpm sensor, so should I try to clear that? It’s the only alarm or fault found, I’m Leary of erasing history as it comes up on the scanner, is that why the check engine light stays on?
@@mariowoodsN5 You should be able to clear it, but the engine fault should have gone away on its own
@@jacquelinetexeira6827 yes Jacqueline there was a pea sized rock on the sensor hole.
I have c250 2012. This error happened to me today but the error disappeared after turning off and turning on the car, but check engine with airbag sign are highlighted on my dashboard ! I’m worried from the ABS pump to be faulty I’ll check the error tomorrow! Thanks for the video 🙏🏼
Did you try exercising the steering wheel all the way over to the left and then to the right like we showed in the video? this helps some people with this problem too.
carbuyingtipscom thank you for you reply, I took my car to the service center and we found that the issue is from the pump it happens suddenly and the steering becomes heavy when the error shows up. I ordered used one from ebay coz the new one is very expensive around 2K!
@@BilalBaydoun86 Wow, that is crazy, $2,000 for a new pump! Would not expect that from an 8 year old car. did you try turning your wheel all the way to the left and then all the way to the right? This helps clear it for a number of people. OR, are they sure that the pump is actually bad? Is it not pumping fluid?
jeffostroff the control module that is connected to the hydraulic is not functioning properly and I found that’s a common issue in w204 you can rebuild it or you can switch it to rebuild it it will cost you 300$, the issue is happening randomly and when it happens the steering wheel becomes heavy and you don’t want this to happen to you when ur driving. I found used pump on ebay for around 120$ including the module which’s very reasonable price but you can see many rates that it can reach up-to 600$ for used one. I didn’t take the pump apart but I don’t think it’s leaking.
jeffostroff the module is around 1300$ and the hydraulic is around 1000$ for new one
Damn… actually worked with “turn the wheel left&right.. ty so much. Do you know why it happend in the first place?
Complex system of inputs that sometimes exercising the wheel an help clear it, but hopefully your sensor is not on the way out. We had to change sensors in our vehicle
Question is it possible that if it’s dirty this will also happen ?
Update: I was able to replace my left front wheel speed sensor following this video today!
My 2012 C250 has C0031 which is the left front wheel speed sensor issue. Is left any different from right? Also is left sensor same as the right sensor (I am asking because I want to know if i can just order using your Amazon link for the Genuine MB RPM sensor). Thanks!
Yes, this sensor is for front left and front right. The rear wheels use a different sensor. the repair is the same as you see in this video, but might be mirror image.
@@carbuying thank you for the reply! I am so glad that I got this issue after your video came out haha. I watched other videos and post and they don't explain in detail like you do. I also followed your video to replace the battery for the first time a week ago lol. Your videos are very visual and easy to understand. 👍👍👍
Just subscribed!
My Benz is 2004 model and when the ABS Light comes on the brake stops functioning. I had to stop driving it because of this. Will this method work for me?
Yes it worked for us, you saw it here in action. Remember to clean out the spot where the sensor goes.
Could you tell me about the 2nd cable of the pair? The speed sensor I understood. I don't understand what is the 2nd cable...
The 2nd cable is likely for the brakes
Thank you ... BTW, excellent video ... helped me A LOT !! I love Mercedes benz. However, I hate the dealership's greed.
Have this problem ABS ESP -garage fitted new Sensor on one wheel as indicated by Diagnostics - Still have the same problem - also Brake Lights coming on so it's not the Brake Pedal Switch - ALSO tried fullleft & right Lock -switch off engine - switch on engine and tried left/right wheel again - STILL shows up ABS ESP ?????
I have all of these symptoms but also brake pedal feels like it’s chattering but it goes away after a couple of minutes. I changed the speed sensors twice.
Did you clean out the area where the senor goes as well and vacuum in there?
I got the same issue today and went to the dealership, they scanned and tell me that the front left sensor is the issue, but they told me to change all four sensors, two infront and two rear sensors. I was going to change only the two sensors upfront. Because i think theres noproblem with the rear sensors. What do you think and recommend? Should i change all the sensors? Total 4. The cost is pretty high for four sensors. Thankyou!
We change only the only sensor that fails due to the cost.
I also have this problem, but the mechanic told me that it's ponpa de abes, I don't know what to do to buy a sou ponpa cable??
@carbuyingtipscom: I have a 2012 MBZ C300 that only has 20K miles on it. One day the famous "ABS Unavailable" error message popped up on the instrument cluster. I bought the BAFX OBD2 diagnostic tool and installed the Torque Pro app despite reading that it won't read "ABS" error codes based on your video. The tool did NOT read the ABS error code as yours did. In fact, after trying 4 times. I got 2 error messages, P1254 & U140A, that had nothing to do with the issues I wanted to resolve. Am I missing something? How come your BAFX OBD2 tool was able to read the ABS error code? Thanks!
Sometimes different models might cause more issues for the cheap OBD@ readers. Maybe your reader was bad, have you tried it in another car? Also many Mercedes owners are using the ✅ iCarsoft MB II Pro Multi-System Diagnostic Tool Mercedes-Benz: amzn.to/2RreN9m which is a much more powerful scanner, but costs much more money. It gives you access to more deeper ECU modules than regular OBD2 ports could ever do.
@@carbuying I tried on my 2016 Honda Civic that has 19K miles. Scanner indicated no faults whatsoever. Will look into the more expensive scanners. Shld still be cheaper than taking to a shop.
Mine was brake light switch..noticed my engine started on push start without pressing the brake. It was partially disconnected
Thanks for your great video! I'm driving a year 2012 W204 C350 Coupe and having the same issue, I got "Run flat indicator inoperative, ABS ESP inoperative" messages intermittently this week, there was one C0031 "Left Front Wheel Speed Sensor (Sub fault)" error code at the first time but the car went back to normal after I cleared the code and restart the engine. Then I had the same messages showing after a few days but no error codes, and the car went back to normal again after I restart the engine...same thing happened again yesterday night while I'm driving on the highway. I'm not sure if I should be worried about it as it fixes itself after a restart...any thoughts? Cheers.
sometime problems can be intermittent as the sensor nears the failing stage, so it might stay on in the future.
@@carbuying Thanks for the reply! But how come there was no error code when the messages appeared last two times? If there was some incorrect data from the sensor , then the computer should generate a new error code, right? I've also seen some owners (from MBWorld forum) got these messages once or twice a year for the past a few years...😂
Did you resolve this in the end? I have the exact same error messages in the same car.
@@alexkatsaros Hi yes, just need to replace that speed sensor.
Thumbs up. Also for the fact you look and talk kinda like Joe Pesci.

@@carbuying Oh man you just made my day with your answer. LOL. Great video. Can't take those fucking three lights out (2 for ESP on the left side and the ABS one on the right side). Im gonna take the car to Mercedes tomorrow. I bought a 2012 C250 last week, bulletproof (ex German embassy) with 100K miles on it. I paid 15K for it (I even had get a permit and all the crap before being able to buy it and drive it). The car is awesome and the bulletproof glass and the 360 degree kevlar on the body make you feel super secure, but I got those three yellow lights on after I tested it out at 240 Km/h coming back home and I was like... "These fuckers fucked me up". A friend told me it may be a sensor or the break pads being exhausted.... anyway, its kinda like I got the car for free (the level 3 bulletproof work alone costs like 40K-50K and its just one year old). Anyway. Fucking lights, I hope Mercedes give me a solution. Thanks for the video mate. Cheers.
There’s one issue that you didn’t distinguish that I think is worth mentioning, since the beginning of your video mentioned other ways to possibly correct the issue. I have the same car and if you get the ABS, ESP inoperable message WITHOUT the check engine light on, then you probably need to just go left to right lock a few times and the steering angle sensor should reset. If you have the ABS/ESP message with the check engine light, then you’ll need to use your scanner, and perhaps it’s one of your abs wheel sensors that need replacement. But if the check engine light is NOT on and you only have the ABS/ESP inoperable message, it’s most likely something simple that is even less stressful and worrisome. I also once got this message when I changed my power steering fluid. But it soon went away.
We did mention about the wheel in the video and it has helped many people.
@@carbuying Right, I’m not judging that. Just wanted to point out that there’s a distinction on whether the check engine is on or not, when the ABS/ESP message is present. Knowing that upfront can make a big difference in understanding the issue. If no check engine light is present, no need to plug in your (or buy) a scanner, at least not for this, since there won’t be an error code.
Hey how are you, my s550 says abs uncooperative, what do you think could be the issue and what's the estimate repair cost.
Check the mercedes forums on this one, but usually the culprit is the abs speed sensors. Get a reader to read out the engine code, then look it up on Google
ABS currently unavailable Run Flat Indicator inoperative how to fix
Can ABS light affect transmission? When the lights came on my car wasn’t accelerating as it normally would.
No the a BS light has nothing to do with the transmission it is simply measuring the speed of the wheels so that the a BS brake system knows how to break in an emergency. So the a BS light coming on just simply means that the computer can't get a speed reading from the wheel because there's something wrong with the sensor
I have a 2015 CLA 250 Mercedes. The ABS came on a few days ago. Purchased an OBDII reader from Amazon and got the COO34 and U140A code. Changed the right front wheel speed sensor. But even after driving the car around the block the light still on. Also the steering wheel is kind of stiff. Is it normal for the steering wheel to be stiff when it comes to an ABS issue ?
No, that cannot affect the steering wheel in any way that we know of. We have also seen where changing both left and right might be necessary, we changed them both on our other Mercedes even though the reader error code was for one wheel only.
The same problem has in my cla 250 2019. There is abs sensor error on my board and steering is stiff.Did you solve your problem Lis M?
What was the solution? Abs and esp unoperative came on. Strangely enough, did a car realignment and that fixed the issue without changing anything.
Hi there great video I have a very strange question but my abs light comes on for a second when my doors lock then goes off straight away (pulling away) (C class) w204 2012, any ideas?
Hi, I have exactly the same problem. Did you manage to solve it?
@@sharonr555Both batteries were replaced but the problem didn't go away till I replaced the Auxiliary battery. Hope this helps
2012 Mercedes C250 Luxury - There are two parts that look very similar. The wrong one has wires coming out of it. My lights did not reset until I drove the car 100 yards.
Yes our 2013 C250 W204 had to drive a few hundred feet before the light turned off.
Checked with OBD2 tools and got the following info.
Diagnostic Trouble Code
C003100 the left front wheel speed sensor has malfunction.
C003164 the left front wheel speed sensor has a malfunction. there is an implausible signal.
Does it mean the front left ABS sensor is faulty?
Could you please tell me how I can test this ABS sensor?
Left Front Wheel Speed Sensor (Sub fault). Not easy for a non Mercedes mechanic to test this, we just replace it when the engine code is 0031
Nice video, don't use this jack anymore, dangerous good stuff
We need more how to videos, I bought a MB as a former mechanic, I admire the engineering and longevity of this reliable brand. However, dealer service departments are run by Used Car Salesmen from the 80s. And the techs from those used car lots. You take the car in, it gets diagnosed, parts are replaced, you bring car back for same thing, and your met with, "Must be something else wrong, hope you got plenty of money". Zero integrity.
Try Bilt Hamber as a wheel cleaner. It's acid free and amazing cleaner
Sounds good!
Hello, I have a problem with the front left sensor, I changed 2 sensors, I also changed the abs unit, I checked the wiring, but the code is still the same, what could it be?
Bad wheel bearings will give error codes for abs + traction control, ive done bearings on my w204 1.8 kompressor without the need to replace wheel speed sensors
I have a 2014 c63 and it's giving me code c198400 fault status during valve calibration any ideas of what it might be?
try the MBworld.org forums someone there will usually know the eanswer
