How to diagnose a vibration and rumble on Mercedes

Автокөліктер мен көлік құралдары

Here is a 2013 Mercedes with about 100k miles and has a vibration at idle/neutral from about 1500 rpm to 4000 rpm range. Also, noticeable when driving. Taking the weight off the transmission mount can reveal if it's weak. This one isn't as bad as the ones I've diagnosed before. Sometimes shops replace the harmonic balancer or front engine mounts, for a lot of $$$ before realizing it's only the trans mount!!

    Motor and Trans mount. They usually wear out atvthe sane time.

    They definitely can, but always check this one first, because it's low cost and on these models is the one that causes vibrations. The front ones often just cause movement in the powertrain, and can leak hydraulic fluid out.

    My torque converter broke abruptly, had to have it replaced and the transmission repaired from the damage. Replaced the engine mounts but still have the vibrating sound around 2000rpm.

    You could have damage internal to the transmission, or engine flywheel. Depending on the model of the transmission, I will usually remove the torque convertor to flywheel bolts and push the convertor in just slightly, and run the engine, if the vibration goes away, it's inside the transmission. If it does not, the flywheel, crankshaft, or harmonic balancer may be to blame. Take a close look at the harmonic balancer with the engine running, they are very very common failures.

    Hello my friend, I have cars cls w219 320 cdi when I start the engine in the morning and I run until I reach 1500 cycles it is vibration and also when I move in a car and I lower the speed when the engine reaches 1500 cycles it vibrates but when the engine reaches a required level, everything disappears. Do you have an idea brother?

    Do you have any warning lights that appeared after the vibration began? Engine misfire can be interpreted as a vibration as well. I would have a full scan done of the modules and see if any diagnostic codes show misfires.

    My 2018 gle 350 was idling kinda rough so I changed spark plugs and now it is even worse and rpm jumps from 700-2000 at idle. 74k miles Any ideas? Thanks

    Typically you want to scan the engine computer first with an OEM level scanner, and see if there are any misfire codes, or fuel mixture codes. If everything is clear there, than put a floor jack under the engine oil pan, with a block of wood in between, and slightly take the pressure off the front engine mounts, if the roughness goes away, you may have bad front mounts. If it doesn't place it under the transmission like in the vid, and see if that changes the roughness. The idle fluctuation may or may not be all of the problem. Also, be sure you used the correct spark part number when cross referenced with OE plugs, and of a decent brand. And absolutely make sure they were torques to spec, Even when tight, they can slightly loosen with heat contraction and cause intermittent misfires.

    You may have bad front engine mounts, but before anything scan all the modules especially the powertrain and make sure there aren't any codes relating to drivability. Usually when the turning the steering the engine module increases the rpm, to compensate for the load. I have seen low steering fluid cause shuddering too. Look under the mounts, with car jacked up and belly pans off, if you see a heavy dark stain, or some times orange/yellow stain under the mounts, they have leaked they're hydrolic fluid and are faulty. I have also seen where cheap aftermarket engine mounts are used to replace and can cause this too.

    Hey there, try the floor jack under the transmission and take the weight off the mount. Whether at idle only or not, this specific mount is a very very common problem amongst alot of Mercedes and makes the craziest vibration alot of techs cant figuer out!
