I just noticed today I am getting a vibration from the motor to the drivetrain inside the car when I gently rev the motor up and when I hold the throttle at 1,800 RPM and around 2,500 to 3,000 RPM. When I'm stopped in neutral and in gear with the clutch pressed in. It's an obvious vibration.

The second issue I'm having is when I cold start the engine I hear a ticking noise. Could that be the oil the factory uses?

Don’t sit and rev at those rpm. Problem solved.



Also, go to the dealer.

Engines have explosions and stuff going on inside them. Vibrations and reverberation at very specific RPMs are normal. Most new cars also sound like a clapped out diesel econobox during cold start. That’s pretty normal, too.

Dealer doesn’t help and says it’s a normal issue. Vibration at any RPM Is not normal at all. It can cause bearing issues and drive line issues.

You explanation is funny and way off. Harmonic vibration can cause many issues. I was just wondering if anyone else was having the same problem.

You can have the car checked by your mechanic, but they likely won't find any issues with it. Your dealer is right, its normal.

I only made the post to see if anyone else is having the same issue. I don’t trust mechanics. I do my own work. Been building race cars sense 1996 . This is my first BMW. Vibration can only occur if the clutch assembly is not balanced correctly, if the crank is also off balance or the harmonic balancer. I’m sure it’s none of those but something might be loss. The vibration occurs with the clutch engaged and release when lightly reving the motor or holding the rpm.


My CTSV, GT350, Z/28, S2000, STI, GTR, never had those issues. The problem is vibration from the motor or clutch assembly can ruin the rod and crank bearings.

I get a little vibration at idle. Comes and goes. It’s done it since day 1 and my f80 was the same. Once I’m moving it goes away, but I can still feel a little in the shifter. IMO normal

Vibration at idle is different.

I think the manuals are dual mass flywheels. That's most likely your vibration, normal for dual mass.

I have had twin and triple disc clutch’s from Exedy,Carbonetics, and Tilton never had that issue. It still vibrates when engaged. Hopefully it’s not an issue. Vibration can also cause the transmission input shaft to vibrate which can also effect engaging into gear at high RPM.

But did the cars you put them on have dual mass flywheels? I am sure it's nothing to concerning, luckily you have a warranty if something fails!

As mentioned above, my car is having a vibration issue as well. Two dealers checked it out and wouldn’t/couldn’t say if they think something is wrong. It was a waste of time to bring it to the dealers. If there’s not a code or a service bulletin, they don’t know what to do. I’m starting to replace things myself. Replaced most of the exhaust mounts (one is backordered). Replacing the exhaust gaskets. Then will look at motor mounts and trans mount. My car has 15k miles, and is a m4 comp RWD.

Definitely not an exhaust issue. It’s clearly coming from the motor and tranny. A exhaust vibration won’t shake the car.

The flywheel design can possibly be it as others have mentioned. It’s dumb that would cause a vibration because vibration is not a good thing

I'm sorry, but that makes no sense whatsoever...

Check the misfire live counters for all 6 cylinders at mentioned RPMs. B58 has the same “vibration” sensation if one or more cylinders fail to combust the A/F mixture properly at low engine loads - replacing the spark plugs usually helps.

Not a misfire.

I'm having a similar issue, but mine just started at 24K miles. Shortly after my recent scheduled oil change, spark plug and air filter replacement I'm experiencing an overall rougher ride, and vibrations.

Everything was running smooth until now. Now at around 2800-3000 RPM's I feel a slightly rougher engine rev than before. Also the overall feel of the engine has changed and just feel off. I wonder if this is due to wrong oil, wrong spark plugs, or filter? I'll be taking it back to the dealer to get it checked out, but not feeling too confident they will identify the issue.

Nothing to do with oil or filter. It can possibly be the spark plugs not gapped properly and the motor is misfiring

Has anyone figured out this issue ? I have the MT as well. I saw a mention of engine mounts. How about Transmission mounts ?

[m331]

Checking in to see if anyone has any more information. Maybe dual mass flywheel?

That’s the only way I think it would cause a vibration. If most people are having the same vibration issues.
