Thank you so much brother, going to get fluid changed in mine. Very professional and slow paced video. Thank you for your time and effort as well to share here.
I had the same problem on my A250 sport 4matic 2016 with 100 000 km on it. Thanks to this video I asked the dealer to just change the oil in rear diff and so far the problem is solved, car feels great in corners now and the little kick once stopped by the traffic light also dissappeard. I will update if problem comes back. Paid the dealer 144 eur for this job. Thank You for information in this video, saved me time and money.
I have a 2018 cla 250 4 matic and had the same issue, I changed the oil like you said and noise went away completely after 2nd day of driving around. Thanks for the advice and saving me big bucks at the stealership. There diagnostic was expensive and they wanted to change out the whole Differential without even trying the oil. BTW oil needs to be changed after 30,000 miles regardless as part of matenance.
Super glad to hear you got yours fixed as well, and that's crazy how the dealer was wanting to approach that repair, not good look for them . Thank you for watching
Thanks so much for this video. I bought a 2019 CLA two weeks ago and it started jerking really bad. I took it to my local MB dealership and they said my rear differential needs replaced. We're just waiting on the adjuster to go look at it. Now, I'm wondering if I could just replace the oil in it to get it pressurized again to possibly fix the problem. It's only got 63,000 miles with a clean carfax and regular service records. It has been a mess.. thanks again!
Yes! funny you say that, because I had a CRV years ago that I used to daily drive, and it started making a noise in the rear, and once I did the dual pump fluid change, it completely went away! I was amazed and always remind myself of that situation, which is why once I remembered about that and heard the noise on the Benz, is why I decided to check and change the fluid on this one first before any hard parts. Thank you for watching
I have got customer with the same car and same problem.It reminds me for CRV diff which had the same problem few years ago, then I found you video.Thanks
Hallo, ich hatte das gleiche Fehlerbild! Auf dem Rücksitz kann man es beim mitfahren sehr gut in seinem Hintern merken. Fühlt sich in etwa so an als wenn man gegen die Bremse anfährt und diese sich mit leichtem knallen löst. Nur nicht so blechern. Öl habe ich selber getauscht Motul 75W 140 Arbeitszeit in etwa 1/2 Stunde und nach einer am Anfang ruhigen Probefahrt ohne anlernen im Allrad Modus und zu erst stärkerem Fehlerbild für etwa 5 min hat sich eine Normalisierung eingestellt und nach 1/2 Stunde war alles ruhig!
The factory information sheet that you used to discuss the diff anatomy @14:12 and the workshop manuals and website sources for this vehicle and similar Merks. Thank you once again for rapid reply. And is there any alternative for "Mercedes part number : 002-989-02-03-09, Hypoid Gear Oil"?
Mercedes differential has design flaw on saving a few parts. Tapered roller bearing needs a nut and lock pin to adjust the spacing between the rollers and the cup. Mercedes uses C ring to retain the cup. It has room to make off center on the axial to caused noise and jerks.
You Save me, i have a CLA 2017, I have the same annoying noise and I think I have the same problem, it has been heard for about 3 months, no mechanic advised me to change the oil!
Afternoon thank you for sharing. do the noise go away as sooner you change the oil or have to be driving it for a couple of miles?? my 2018 have the noise whenever i turn and exactly what you described send to change the oil but i was told i have to drive it for about 500 miles to check it and make sure it work. any idea?
Thank you, thank you , thank you, really thank you... you know how much money I save my self... i bouth the mercedes oil, it was a 105dllrs a quater they told me it takes two and some onces, so i bouth only two but in reallyty takes half a quarter... a soon I change it the noise when off... yessssss tomorrow i will return the other quater to the dealer
Thanks for showing the chassis ears in use for this diag, Sadel. I'm curious what the mileage was on the rear differential fluid and what service interval Mercedes recommends for it? Thanks for sharing your skills with us in another great video, Sadel!
@@DTEAuto i have the same problem with my 2014 merc cla 250 4matic where is your shop located please i need someone to take a look on my car too. Mercedes dilership just ask me for 6k$
What mileage was on the vehicle when it came to you? It's crazy. that Mercedes-Benz do not specify any fluid changes on the maintenance schedule for the CLA250 4MATIC but they do state an interval for the CLA45 4MATIC. Never heard of a car with a rear diff that wouldn't't require a fluid change yet Merc state it's lifetime fluid.
Hello, I had the same error picture! In the back seat you can feel it very well in your butt when you ride along. It feels like you're hitting the brake and it pops off. Just not so tinny. I changed the oil myself Motul 75W 140 working time in about 1/2 hour and after an initially quiet test drive without training in all-wheel drive mode and only a stronger error pattern for about 5 minutes, a normalization set in and after 1/2 hour everything was quiet !
I have a 2016 gla45 that I’m about to buy a new differential for but I have already changed the fluid and reset the codes but I still have the noise and also get a “4matic unavailable” signal when I launch it
This is a common problem and it seems like the fluid change is just a temporary fix. After watching your video I'm wondering if it's more of a software issue.
Hello, can you please provide more informations? I changed the oil fluid twice and still have a small shock/nock when changing gears between D1 D2 D3 when the car is cold, I dont know what is the best solution yet
I have the same problem I will be taking the car in for them to look at it and will reference your video . By the way is it also possible to dis engage the seleniod were the noise goes away and the car operates as a FWD
I would venture to say that if it is unplugged it will keep it from attempting to activate which would I guess keep the noise from happening, but possibly turn on an error light on the dash. Either way I hope that the fluid change helps to rectify your issue and thank you for watching
at what speed do you have the problem? i have a similar problem knocking noise only if I am at speed of 0-25mph, in drive mode D1-D2-D3
Both if I accelerate, and if i don't accelerate or break. the noise increase in frequency if I turn right or left. no knocking noise in neutral and rear.
I can't remember exactly at what speeds, but if you are trying to isolate the rear diff, try unplugging the solenoid and see if the noise goes away. If it does then the noise is occurring when the solenoid is applying the clutches, and so at that time I would at least attempt to do the fluid first. Hope this helps.
Same problem. Haven’t changed the fluid yet. So to avoid further damage with the 4matic trying to engage, I have disconnected the socket. No noise. Will try the fluid change hopefully it will fix it so I can reconnect the 4matic socket
Hello, I have CLA45 and facing same problem, only difference is it sounds clearer and louder if I steer in any direction and go reverse, I have changed the oil at the dealer twice, the car has 70000km, this happens only when the car is cold, did you solve the problem?
Great diagnostic sir. I am curious, as someone who is always working on different brands, (you could think of me as an independent) how do you charge fairly to yourself and the customer on an issue like this? I am always curious about the business side of being an owner/technician and wonder sometimes if I had to change up how I make a living, could I make it on my own? Is it a case of I charge X amount per hour and you pay for however long it takes to find the issue? That seems fair to me, but customers tend to distrust people in our trade. I have been out of the public service game for 20 years, and I honestly don't know . I maintain a fleet of heavy equipment and light duty trucks for a company, so I never have to worry about customer relations (except for my equipment operators). Anyway, nice catch and I hope to see more and more of these in the future.
I would say that yes that would be a good guideline, charge your diagnostic time, the the repair time , and then add materials and such. And to try and keep it as close to that with most of your work that way you have consistency when charging. But it all becomes harder to keeping it simple when you have odd ball diag stuff, it's hard to always profit when doing odd ones, but for me at least, it's more important to get to the end goal of reaching a fix that no other shop did so that in doing so it helps to gain and or retain a customer and at that point also gain their trust. Once you have their trust from the good work you give them, then that's when you begin to profit because of repeat business without question. I hope this gives some insight or at least food for thought, and also thank you for watching
Hello i have the same probleme in my gla 220 cdi 4 matic A little kick once stopped by the trafic i change the oil but the problem is not solved The dealer said that i have to change the oil a seconde time to solve the problem What is your opinion ? Help please
I have just disconnected the 4matic socket from the rear differential to save it from further damage, before changing the oil… Hope to change the fluid soon. Now the 4matic is just a FWD
hi! Is this diff the same as I have in my 2014 gla 220d 4matic? Got a call from my mech saying the clac clac noise when turning the steering (in movement) is coming from the diff.. he just talked about replacing it, not changing the oil… would it work in this case? Thank you
@@DTEAuto thank you so much for replying!! Talked with the mech today - he said my 2014 GLA is "permanent" 4WD - he said that there isn't any clutch or whatsoever which I think isn't true because of what I got from this video. I've learned that a lot of owners are complaining about this clicking sound but it can be misdiagnosed when it's a PTO failure or even a driveshaft bearing failure - have you check it as well? I've also found another owner saying there is a breather that gets clogged which stresses the system - wondering if this was your case that a oil change fixed it?
@@DTEAuto yea apparantly these 4matics use a electrohydraulic clutch. Found a company that can replace it or even clean it. Replacing it cost 800+ which they say problem goes away or clean it around 350+ which can also help the problem but no guarantee. Both methods they change the oil, thinking about doing the clean only + oil
@@parth7092 I live in the Netherlands, and i found one here. The guys fixed it in 1 hour, there is a electronic clutch in the diff which needed replacement. It fixed my problem directly also a oil changed happend.
I have a '14 CLA as well and I have a noise that no one can figure out - it reminds me of a spark plug issue sound and it seems to get faster as I accelerate and it slows as I go slower. But it's not the spark plugs. Unfortunately I can't hear the sound on this video :(
Español te explico si andas buscando que tu mercedes hace un ruido que truena y no saves porque ... usualmente los allwelldrive hacen ese ruido enfadoso... cambiale el aceite del diferencial pero ponle el original que vende el dealer y en cuanto se lo cambias el ruido se va.... garantisado.. ya que el aceite se adelgasa demasiado y pierde su viscosidad es por eso que el ruido se wscucha mucho cuando esta frio, pero el nuevo haceite tiene todo la viscosidad nueva que luego luego empiesa a trabajar.. esto ws por si
gracias amigo. tengo ese ruido hace mucho tiempo y pense que se había dañado el diferencial completo. aun sigo así con ese golpeteo. espero que con el cambio de fluido vuelva a la normalidad. acabo de comprarlo.
I want to delete de rear diff and driveshafts to make it fwd only. I never had awd even the crvs i had back in the day i deleted them instead of replacing the rear diffs... Do you think its doable on these cla. Im thinking of leaving the diff selenoid plugged in so the computer still sees it instead of trowing error code? Need your input on this... Do the rear axles go thru the wheel bearings? If yes i will just leave the outter part of the cv joint there to hold the bearings together just like i was doing with the crvs.. I paid low money for the 4matic. I love fwd better. Thank you!
I am not sure if delete of the rear drive will work on these, I guess all you do is try, but I know just how much everything is monitored that I'm not sure how it will act.
@@andresa7239 I had a CLA 250 in 2014 and my understanding about tire monitoring was a genius system that measures the timing of the revolution of the wheels. They should all rotate pretty much the same so when the computer reaches enough variance of the revolution, the car registers that as a wheel size change and alerts as a low tire pressure. That’s how it was explained to me and I think it’s genius. I never had any issues with the monitors when I owned it and I did have a tire go flat (blowout at highway speed) and the system worked 100% as it should have. Hope that helps….. So there are no tpms sensors in the wheels to replace that I know of
I am not sure if it is the same, but a big clue to check if it's the same is to look for the 2 wire solenoid located at the rear differential. If you have one then it is possible to have a similar set up as this one. Hope this helps and thank you for watching
As in my case and as I've been told since posting this video, it seems the fluid change does rectify the issue most of the time. Give it a try, thanks for watching
Afternoon thank you for sharing. do the noise go away as sooner you change the oil or have to be driving it for a couple of miles?? my 2018 have the noise whenever i turn and exactly what you described send to change the oil but i was told i have to drive it for about 500 miles to check it and make sure it work. any idea?

Any idea where the tire monitor is at (modules)
@@andresa7239
I had a CLA 250 in 2014 and my understanding about tire monitoring was a genius system that measures the timing of the revolution of the wheels. They should all rotate pretty much the same so when the computer reaches enough variance of the revolution, the car registers that as a wheel size change and alerts as a low tire pressure.
That’s how it was explained to me and I think it’s genius.
I never had any issues with the monitors when I owned it and I did have a tire go flat (blowout at highway speed) and the system worked 100% as it should have.
Hope that helps…..
So there are no tpms sensors in the wheels to replace that I know of
what or oil used for a rear transmission?

Hi, Do you know if the GLA 220 cdi has the same differential?
I am not sure if it is the same, but a big clue to check if it's the same is to look for the 2 wire solenoid located at the rear differential. If you have one then it is possible to have a similar set up as this one. Hope this helps and thank you for watching
@@DTEAuto where is your shop
I have the exact same issue with a 2015 GLA
As in my case and as I've been told since posting this video, it seems the fluid change does rectify the issue most of the time. Give it a try, thanks for watching

Afternoon thank you for sharing. do the noise go away as sooner you change the oil or have to be driving it for a couple of miles?? my 2018 have the noise whenever i turn and exactly what you described send to change the oil but i was told i have to drive it for about 500 miles to check it and make sure it work. any idea?
it should almost start working properly if the fluid was the issue, make sure that it gets reset/calibrated afterwards
