2009 C300 Misfire RPM Surge PROBLEM SOLVED

- 2009 C300 RPM Fluctuation, Grind & vibration from the rear wheel drivetrain.
For approx 30k miles I experienced what some would describe as a Misfire or a power Surgea in my 2009 Mercedes Benz C300. I made several trips between multiple dealerships and Mercedes Certified Mechanics until I was able to find the solution. Ive also looked on youtube in hopes for somebody to have this same problem which I never was able to find. So i made this video to help other people who may be frustrated with this very same ongoing problem.
What I forgot to mention in this video was the fact that this fix also got rid of a rear grind noise and vibration that i would hear and feel periodically in between almost every other few random times the car shifted gears. Although that problem begun maybe 10k miles before the misfire problem. I assumed I had a problem with my differential or transmission.
UPDATED NOTE: You will need to have the fluid changed again every 30k to 40k miles thereafter. When you notice the problem coming back all over again that is when it will be time to have it changed out. So far I have had to do this twice now and both times it has fixed my problem.
you are amazing, you should be paid for this kind of information. it has saved my wifes car !!! thank you thank you!!!!!!!!
I just got one and it's doing the same thing, I was told it was the trans fluid change and this confirmed it, thank you so much
How long did your car take to fix the problem after you change the fluid?
Did it work
bro i change it last day transmesion fluid and he doit same error again! i dont know how to do! i have same problem like this video
🤝🏾Thank you. Your the only person I’ve seen on TH-cam that had the same problem as me and solved it
Was having the same issue with my wife 09 C300 4MATIC. THE Transfer case was low on oil. Drained it and topped it off and it fixed it.
I have the exact same problem and I have done several attempts to figure out what's wrong. After trying all same repairs as you did, I was convinced that the issue was related to the exhaust system but appears that catalytic converters are fine, so I will try what you did about changing the transmission fluid next. I hope it works! thank you!
Hello did you change the transmission fluid and it stop?
@@mohammedauwalaliyu7667 Yes, I changed the transmission fluid and it stopped the vibration.
@@ocanavic what symptoms did you have? hard to start? check engine light? etc?
@@ocanavic ?
Thanks for sharing, o do allot of highway driving and mine started doing it, I was hoping it’s not the transmission itself I guess it’s time for a transmission fluid flush. You’re a life saver for allot of ppl. These cars are a pain when it comes to diagnosing
what symptoms did you have?
ive been on youtube the past month trying new things every day. I replaced the entire mass air flow sensor, all8 spark plugs, all 8 ignition coils, fuel pump and fuel sending unit, engine oil change, new air filters etc. THE ONLY THING I HAVENT DONE YET IS THE TRANSMISSION FLUID AND I REALLY THINK YOU JUST FOUND MY PROBLEM!!! my cars hard to start sometimes but when it does start, it starts up every time. I noticed that almost every single time i first start the car and try to go into reverse or drive, the car doesnt move. Im going to change the transmission oil and case and filter this week and i will update you asap to see if this is my problem. could you tell me every symptom you had? i have an 07 mercedes s550 but theyre all practically the same.
@@rapvault98 did it work?
Finally. Been looking for a solution for this issue have had the car for 3+ years have been maintaining it perfectly and this issue has been annoying the living hell out of me
Did it fix the problem?
Hi this video changed my life. I did a transmission fluid change and the problem is slowly going away
Check the front differential it’s probably 0 oil or it’s damaged
Lady who ever u are your life saver u Hurd I’m telling u sorry for the scams I literally just was going thru it to lost dam near 2 racks into my car but shit life saver😂
My 2012 does that have 119k almost never changed fluid before and changed intake yesterday because the computer they plugged said same thing. Definitely gonna look into it thanks.
Thanks i changed sparkplugs and still have problems. Maybe i will try transmission fluid. Smart gal, thanks so much!
hi did it fixed the issue?
We changed oxidation sensor fixed the issue.
@@cy0078 u would have had an check engine light on or not?
Yes the light was on and the Cruze didn't work either.
@@Ali-wf3rjYes and the Cruze didn't work either. After changing spark plugs and oxidation sensor everything fine, for now
Thank you so much for this video I have the same car with the same issue now. I was truly lost. This video helped
Im glad to have been of help to you, When your free lets talk trucking!

@@rapvault98 did this fix your problem??
I have the same problem with my c300 2008 & I had a moment where the car wouldn’t want to move in reverse , now I’m going to check my transmission fluid & change it thank you I need to check my transmission fluid!
Your welcome. I never made a TH-cam video before. But because I've spent thousands of dollars and alot of time trying to find somebody somewhere with the solution and came up with nothing. When I finally figured it out I couldn't help but to help other people with this problem. I just knew I couldn't have been the only person.
@@patriciahanzy4533 turned out my transmission & fluid was burnt, previous owner definitely didn’t take care of the car
Thats Awesome to hear! So it fixed your problem?
@@rodrigomarquez7635changing transmission fluid helped?
thank you so much you just don't understand how helpful this was ...
I have a 2011 c300 and it’s been doing exactly what yours is doing I haven’t thought of doing the transmission fluid change I am going to do that next!!
I also have a 2011 c300 4matic that has begun to do the same thing. Did trans fluid change solve your problem?
did it work? what symptoms did you have?

I just test drove one. The car was doing the same thing, the exact same thing. I am going to buy that car.
The manual tells you when to change a certain things. And whenever you buy a used car you should always change all oil and filters
You are a life saver I couldn’t figure it out to save my life had the same problem

@@rapvault98 did you charge the ECU or the sun sensor?
@@gamechangerrc4633 what do you mean by charge it? It’s plugged it what does that mean?
?
Did this fix your problem? Its very hard for me to understand why none of the usual techs at the dealer and or my own mechanic had the experience to automatically know what my problem was.
It’s not necessary a misfire. It’s called a converter lockup
Thanks for the info
Great video! It’s time to change that transmission fluid
Mz. Hanzy, I would hope going forward you change your transmission fluid every 60K miles. In addition to that, I would hope you change your differential fluid front and back. This too should be done every 30K miles.
Ty lil do it for sure ! The dealer say i need to change the transmition for 9 000$ ! Im going to do it really soon
I made it ! I change my transmition fluid and you know what ITS WORKED ! TY VERY MUCH I LOVE YOU ❤
thank you so much!!...hailing from jamaica!!
let me tell you my symptoms because i think we have experienced the exact same thing. I have multiple misfires in 6 of the 8 cylinders and my car transmission shifts so bad and slips. Perosnally, ive been on youtube the past month trying new things every day. I replaced the entire mass air flow sensor, all8 spark plugs, all 8 ignition coils, fuel pump and fuel sending unit, engine oil change, new air filters etc. THE ONLY THING I HAVENT DONE YET IS THE TRANSMISSION FLUID AND I REALLY THINK YOU JUST FOUND MY PROBLEM!!! my cars hard to start sometimes but when it does start, it starts up every time. I noticed that almost every single time i first start the car and try to go into reverse or drive, the car doesnt move.

Well sir try replacing the coil packs and spark plugs again. My car didn't have any actual misfire codes, it just felt like it was misfiring. My transmission didn't slip like the noticeable shifting problem when your loosing a transmission and it slips into neutral. and the transmission fluid shouldn't have anything to do with an actual misfire problem. those 2 seem unrelated. You can try changing the fluid, but in your case, from what your describing to me I would only think that will worsen your problem. I am so sorry I wish i had better answers for you. Although I am still curious to know if you did change your fluid and if it improved your situation at all? i highly doubt it would change it in full, but anything's possible .
Did this work for u? I am facing similar problem. I have no engine codes or anything but still seems to misfire. Spark plugs were replaced not too long ago. So how did it work for u?
@@ammarahmad6526 yeah it worked for me. You wont have any engine codes but youll have a tcm code which all obd readers dont read. I would do it, eventually you'll get misfires if you let it get too dirty and thats what happened
to me
I cant go over 50mph. My rpm’s stay below 3 and go up and down…. It feels like a vacume leak or someone said a throttle resets would do it. Idk maybe a Tran flush will do it but u said it’s irrelevant. I had a misfire before this and changed spark plugs and coils and injector and then i deleted the code and it ran fine for a day and went back to breathing for air and jumping rpm’s
@@davidmendoza5522 it’s the trans change your fluids every 40-60k miles especially on these Mercedes’ ! Anything jumpy on rpm’s would be your trans fluids check the dipstick before because if it’s too late flushing your trans would only ruin it
hello Patricia Hanzy my car has the SAME problem and sometimes when the transmission is making forces it vibrates. I'm going to take it to change the transmission oil and filter. My car is 2008 Mercedes c300 and it has 190,000 I hope you solve the problem I want to thank you🤞
Sounds like the same problem to me!! Let me know!
Do you beat on your car? Do you always take it to Mercedes for maintenance or do you do it yourself?
did it work?
🙌🏾🙏🏽… THANK YOU FOR THE INFO !!!
Thanks for the heads up!
thank you for sharing great information.
Glad it was helpful!
FIRE🔥
Damn I got the same problem and spend a lot of money.mine is a 2011 c300 4matic luxury I even took it to mercedes change spark plugs nothing change I got 143000 now I’m going to try this and come back to let you guys know cause In a point I thought this car had a ghost in it lol that shit made me get a whole new car loll but I’m still driving it as my day driving to go to work etc and protect the new one I’m not gonna lie I love this car and it is so strong,reliable and smooth sometimes you don’t feel it in mine and it start doing it you put the transmission on neutral it stops so I want to solve the problem I’ll be back
please let us know if this solved your problem. it solved mine with no help from the dealer at all on this subject. although i will say you will need to get it changed about every 50k miles which is usually when it starts acting up again. so far ive had to do this twice now. Although everytime after changing the fluid my problem disappears.
Did you have a check engine light on? Also if so, did the fluid change get rid of the light?
NO check engine Light will come on for the transmission fluid. if you have a check engine light on and its doing the same thing or similar I suggest you check your coil packs by rearanging them with a new one. look for videos on how to do that. or maybe the problem is you have more than one simple problem.
Thank you very much !!
I have a 2011 glk350. Having the same issue. I changed the oil, the pcv, spark plugs, coil packs, new battery, today just did the transmission oil change, which the mechanic said the oil looked clean from the transmission. My issue is maintaining speed at around 20-35 mph. Meaning maintaining speed with traffic. The idle just jumps up and down. It has a new fuel pump and new fuel filter. New MAF, new gaskets from throttle body and MAF, new air filters, new intake manifold, and new o.rings on the injectors. Not sure if it's my torque converter or maybe a vacuum leak somewhere since all.those.hoses are original
C220 I have had the same issue, fixed every fault, code sensors, they have all gone away, just changed transmission fluid and Money still doing the same thing. Did you manage to fix yours? Thanks, Ricky
@@rickygibbs9403 not yet the shudder from taking off went away, however I still have the rpm and mild hesitation which I feel slightly. Although the trans oil change did make it a bit more lively. This coming week I'm going to take it for the torque converter and have them change it. Will let you know. I have heard about the lock up clutch solenoid that sometimes goes bad as well. So I'm thinking of doing them both. I already have the solenoid with me. I'll let you know what comes up.
Ok thank you very much four your time mate
@@christhegamer2607 no my one drives perfectly fine, just hold back every now and again like in the video with the rpm so frustrating I’ve spent nearly £1000 and still the same thing drives perfect in sports mode don’t really know. Is it Justin comfort really plays around
Hey I've just done the transmission fluid change and it's still doing the same thing. I'm just leaving a message here so I can get notified when you do the other stuff so I can know if it worked or not.
here at the shop bout to try this, will update.
it truly does do wonders off the rip u will feel it recirculating a bit adjusting to the right levels etc. i ran it maybe a cool 30 mins on drive felt wonderful, then i wanted to try it on sport, it also felt wonderful such a difference but u do have to run it a good other 30 mins and let it run, but no yeah, great advice if u feel any crazy vibrations from trying to go higher in speed, or getting weird pull backs going up the hill i strongly recommend this advice, feels buttery smooth on the highways now.
Waiting for your update.....
@@soultribeatl6854 Thats great!
update lmao the fluid change did give it back PLENTY of life, jr actually wouldn’t shudder or vibrate like it did before
BUTT i had low compression in bank 3 causing an annoying misfire that didn’t even turn check engine light on. so long story short i sold it and getting me another c class.
Thanks for sharing
Tengo este mismo problema solo pasa en frio entre 1.500-1800 RPM en cuanto la temperatura del motor llega a 60 grados desaparece ese temblor, cambie la valvula de caudal de gasoil y sigue igual sabeis la solucion? Gracias
Hi I have the same problem as you but mine is a petrol engine C200 kompressor. Did you manage to fix the issue?
Im doing mine Tuesday and i changed the manifold too and air flow sensor and i never had it changed before and now has almost 120,000 miles i let u know
Did it fix your problem?
@@patriciahanzy4533 it kinda did but i still have a slight rpm bounce
Change gas stations try nonethanol premium
i forgot to mention if your fluid was super nasty. your going to want to drive on the new fluid about 500mi and change it again. reason being theirs a great amount of fluid that cant be drained, So you have to mix the new with the old a bit in order to get more of the filthy fluid out. The car is absolutetly case sensitive about this stuff. mine had that come bac after 10k miles on a very low low scale. i changed it again and ive had no problems its been 20k mi since
Hi, i have same issue on rpm, but no checkengine or misfire. Car has horrible vibrations and shiddering when you need torque, did yours had same vibrations ? I jist bougt 2009 c350 and nobody knows if ever had fluid changed
Check the gear speed sensors inpu and output they might be covered with gunk. If you need a transmission fluid change do so as well
Finally i done with vibrations. Changed transmission fluid, rear flex disc coupler, rear tires and it's perfect now
I’m at 160 and it’s been doing it like 20,000 miles finna do this exact thing prolly next week and hope for the best
Thanks a lot
Thank you
Nice video
Hi was the rpm surging while on idle ? Or just when driving ?
Thanks
Any help would be greatly appreciated. Mine is the same as the one in the video runs perfect just hold back a little bit with rpm. Other than that the car works perfect really stressed out now Transmission fluid didn’t work for me unfortunately 😢 i’ve spent £1000 trying to work out what’s going on with this car anybody with a good idea please share many thanks Rikkie
I'll fix it for you for £250
That’s all you did was to change the transmission fluid?? My car is doing the same thing driving me up
Out of my experience, if you don’t want to waste your money, give it to the main dealer let them diagnose the problem then fix the problem because if it’s not what they say is then they are liable so in all honesty, just let the main dealer deal with it by the time you work out what’s going on you would’ve wasted more money than they want to do the job in the first place take it to main dealer. If it’s something like this in the video you will be wasting money there’s about 10 different reasons your car can act like this. I will let everybody know how I get on next week with the main dealer hopefully they fix my problem. If not, it will be at their expense.
Did it fix it??
Thanks!!
You bet!
How long did it take after you change the oil for the car to tix the issue?
I just don’t know what to do next. I’ve just done transmission fluid test drove for half an hour after picking up from the garage and it still doing the same thing killing me😢😢
Did you manage to fix it? I fixed mine and it was not the transmission fluid
Mine is starting to do that at idle. Just drop a bit here n there. Doesn't do it while driving but only at idle
Im having the same issue with my 2010 glk 350 some mornings takes a second longer to start other mornings starts up just fine ,when the rpms start to fluctuate like yours was doing in the video and feel a slight vibration, it also at times is sluggish on accelerating When i get up to highway speeds car runs like nothing wrong with it , no check engine light no codes, i have a appt at the Mb dealer tomorrow morning to replace transmission oil and filter do you think im having the same issue as you were and it will fix my problem?
Did they figure out what was wrong? Having the same issue?
Mine didn't solve it I did fluid and filter. do I need to drain the torque converter too?
Same here bro just did oil and filter change still nothing
@@SlickDriven I did it twice now nothing
I had same issue right now and have also changed the transmission fluid my question is which type of fluid is the best and how do I get it
Well I couldnt answer that, My honest advice would not be to change you own fluid if you dont know what type of fluid. Im not sure if your aware or not but the transmission is sealed and you need special equiptment and tools to suck the fluid out and pump them back into the transmission.... Honestly I couldnt begin to give you any advice on how to or what to use except only use genuine Mercedes fluids directly from the dealer. I wouldnt waste my time using anything else. Now after you change your fluid You will have this same problem again in about 45k miles and at that time it will be time to change your fluid AGAIN!
My car is doing the exact same thing, I just replace the fluid and filter but still doing the same, just wonder if the issue was fix after driving the car a few miles or “instantly” thanks
Mine didn't get fixed maybe I got to di it again plus ima drain the torque converter
@@Hondalife_8 mine it’s working great now, I did a flush with 2 times, the second time I put sea foam transmission cleaner then I add a torque converter additive it’s called lube guard in a red bottle and the other one I put is a dr tranny insta shudder fix tube it’s also a small red bottle, it’s about 20 a bottle but man it really works
It's not the fluid. Does it berk when driving? Especially in the morning when the engine is cold?
Mine is a new transmission fluid but still surge but i recently done a repair vgs panel could it be the think causing the rpm surge
at 40k miles you will strt to notice the rpm problem. in my case that meant every 50k miles after 150k i ve had to have it changed to fix the problem. Ive changed my fluid twice now. the reason for every 50k miles after your 1st initial fluid change, is because the mechanics can not fully drain your transmission, only partially which leaves a large amount of very dirty fluid behind. that mixes with your new fluid...
you say you have a new transmission, it could be very likely that the mechanic whom put it in didn't fill your transmission all the way with fluid, to do that he has to hook up the obd reader and check the levels at specific heat temperature points to determine if its filled correctly since the transmission is fully sealed and doesn't come with a check stick for you and I to access!
Also if you just had your transmission changed did your mechanic use all original MBZ fluids and a New Filter and Screen?
I say take it to the dealer and have them check for trouble codes.
How many miles were on the car when you changed the fluid? if over 200k then i think you need to do it again. because that would be alot of dirt and metal to mix with new fluid! it would automatically make the 1st change of fluid still very dirty. Just alot less dirty. Although it doesnt take much dirt to clog the filter and screen of the transmission. Its not like a Tahoe where you can run it 300k and never change the fluid just add some every now and then. This car is case sensitive for some of the most silliest things.
😁 my 2010 is doing the same thing. Ima change the tranny fluid and see. I purchased it already just didn’t do it.
changing the tranny fluid on these cars is not something you can do without the proper tools. its a sealed transmission therefore it has to be sucked out and pushed back in. I believe im talking about the mercedes and not my lexus right now? Nevertheless you still have to reset the transmission ECU.
Is this why my 2009 c300 is slow to start from 0-60... i feel like i'm the slowest car on the road.
That i couldnt really tell you!
Change the engine and transmission mounts
@@Mr-Miracles Funny, I had to change those as well during that period of time. but the fluid change fixed my main problem!
Never Take ur car or any car to a dealer. And find a good Mechanic
You need air in you're tires.
