Been hearing a strange noise when driving off from a junction. I had my windows down and when accelerating away and car changing out of first I get a vibration noise like grrrrrrr sound and same after it shifts out of second.
Can someone help

nickid

please help.

still having this strange vibrated noise from my engine.
when I rev slightly, It makes a noise then nothing until I let off and it does it again?????
I thought it might be the tensioner but no chain chatter on start up

sammydragon3

i get that grr the first shift of the day sometimes i do sometimes i dont

my chain is on its way out and im getting that mf fixed

the chain doesnt need to make a noise...ask hogger

nickid

It's doing my head in not knowing what it is. I saw a video on you tube of a guy selling an engine that made the noise too but he didn't get make to me

nickid

Do you think it's the chain on mine? The sound seems to be round about the middle of the engine, not at the front where the chain is

sammydragon3

did he measure the slack on the chain? he should have manually rotated the engine to listen if the valves are hitting

any check engine lights? why did u take the car to him in the first place?

nickid

No lights and car running fine except for the noise. Been told its the cam shaft adjuster

sammydragon3

how many miles? did he do a compression test? did he measure the slack on the chain?

nickid

It's done 70k miles and I haven't had the can cover off yet to check the chain. I have no noise of a loose chain on start up only the brrrr sound when acceleration for a split second and when lifting off the accelerator again I get the brrr sound for another split second

nickid

Its camshaft adjuster inside the engine. I just took to connection of the solenoid and it doesn't make the noise and when I put it on again it made it.
so its a new camshaft adjuster

Javvy

can you please post some pics of where exactly this camshaft adjuster solenoid is located on the engine....I am having the same exact symptoms as you mentioned....."brrrr sound when acceleration for a split second and when lifting off the accelerator again I get the brrr sound for another split second " .... this brrrrr sound is ever so mild ...how much and where did you buy the solenoid from and what is the part number.....I would love to get rid of the annoying brrrr....

thanks a ton
javvy

nickid

if haven't bought mine yet only just been told that is the problem, but this is a picture of the solenoid I nook off google. its sits between the to red arrows at the front

nickid

I am very unsure what I need to buy or how to replace it

Javvy

What you are describing is one of those things that is really hard to explain to someone and it throws you all over the place. I had this problem where it makes that sound between certain speeds and when you let go of the gas its okay and when you press the gas again it would make that noise, i always felt that it was from the middle to the rear of the engine. Anyhow, check your tanny fluid level. This was the last thing i tried and this was where the problem was. If your tranny fluid is okay and your car shifts alright otherwise then ignore my post. Else you should also read up on glycol contamination in tranny due to bad valeo radiators. Anyhow, for now if that happens between certain speeds or when you car is about to shift then I would first and formost look into the tranny fluid level and report back.

CHECK THE TRANSMISSION FLUID RIGHT NOW!!!!! which u probally cant with no dipstick

its not the chain or tensioner

nickid

Will check it mate but my noise happens for that split second (brrrrr) 1500 revs then them revs go down I get the same sound for split second (brrrrr)

ammar_rage

Yep sounds like tranny fluid level. Check it and report back. observe the hot and cold markings if you got the tool. Its best to check it when the car is warm or when the temperature is above 80C on the display, also you always check the tranny fluid level when car running.

Once you report back on the fluid level then we'll know where to go from there.

nickid

How do I check the level

ammar_rage

Here you go

Or if you got some other dipstick that is flexible and long enough to down the tranny dipstick hose, then i can measure the length from my dipstick and let you know how many CM/Inches you should get at 80C with the car running.


Hope that helps, if you gonna keep the car then its worth spending the money on that thing. My oil sensor gave up on me long time ago, i use the same dipstick for the engine oil level too, i know some of you will say that its not long enough but i got it marked up on the metal part

nickid

Checked my levels and all fine.In my earlier post a disconnected the camshaft adjuster and it stopped making the noise

asuliman1990

My car is have the same issue, the brr-brrrr sound in neutral. I am sure this is not the transmission because this sound happens in neutral and when shifting (6spd). I'm pretty familiar with Honda's and this is my first Benz (02 C230). How tough is it to replace the cam adjuster?? Anyone ever resolve this?\

Thanks

nickid

My wife's and mine both make this noise now

SebaS

Did anybody found solution to eliminate this sound?
