Thank you as the steering wheel trick worked for me. I still need to get it checked & hopefully not going to be expensive

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.

[@dbash2004]

Hi from London. Another channel mentioned that when replacing the abs speed sensor you usually have to replace the speed sensor ring on the wheel hub. As the sensor reads the ring as it turns on the wheel and it's not unusual for them to go as well and its not a easy job to replace them as it involves taking the hub off.

[@diegolaiz7723]

[@BUR70713]

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!

[@carbuying]

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.

[@AlGolzari]

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.

[@carbuying]

We did mention about the wheel in the video and it has helped many people.

[@AlGolzari]

@@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.

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

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.

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.

@@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?

[@BilalBaydoun86]

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.

Is it safe to drive my car like this while the parts arrive?

[@Parknest]

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.

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).

Can ABS light affect transmission? When the lights came on my car wasn’t accelerating as it normally would.

[@carbuying]

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

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.

Any advice what I need to do here please? I really appreciate your help!

[@carbuying]

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.

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.

What if my 2010Mercedes Benzsport C300 dash tells when I first insert the key to take key out then the ABS AND ESC ALSO COMES UP WHATS THE ISSUE HOW DO I FIX THAT

[@carbuying]

Any car who's ABS light turns on you will have to do the same procedures as shown here in this video but you will not know what is wrong until you plug in the OBD2 reader to read out the error code from your car that's the first step.

Hey how are you, my s550 says abs uncooperative, what do you think could be the issue and what's the estimate repair cost.

[@carbuying]

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

[@ralphgomez6804]

Wow, that’s totally awesome, thanks

[@lynncarman8134]

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.

[@carbuying]

Did you clean out the area where the senor goes as well and vacuum in there?

[@machongtalong1210]

@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!

[@carbuying]

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.

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?

[@7500.B.C.E.]

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

[@Geekedout730]

Question is it possible that if it’s dirty this will also happen ?

[@GreenAmbience1]

I have changed all sensors yet same problem. What else can one do

[@carbuying]

Did you try to vacuum out where the sensors go? Are they the right sensors made by your manufacturer? Sometimes people will buy a cheaper brand but turns out to be bad. Also maybe the ECU is the problem, maybe it's getting a good signal from the sensors but just not seeing it. Did you drive the car a few miles and exercise the steering wheel all the way left then all the way right?

[@TheNicolay96]

Damn… actually worked with “turn the wheel left&right.. ty so much. Do you know why it happend in the first place?

[@carbuying]

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

[@percypan4385]

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.

[@carbuying]

sometime problems can be intermittent as the sensor nears the failing stage, so it might stay on in the future.

[@percypan4385]

@@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...😂

I just replaced the right sensor and suddenly after a 100 yards the light came back on , the diagnostic shows the same sensor we adjust the axle it had a small play on it , erase the code drove it for 2 miles then the light came back on. !! Scanner shows now the left sensor, I didn't replace it we adjusted the left axle clear the code and 20 miles or so and bam!! The light came back on .... any ideas ???? I will put the scanner tomorrow and see what it shows up. Any help I will appreciated.

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.
