Clutch "judder" - 6MT

[Aaaaaaaaa]

Actually now I think it's some strange interaction between the hill hold assist and anti-stall. I was trying to park on a slight incline and I noticed that after releasing the brake pedal and getting read to apply throttle, the gas pedal response was quite laggy thus when engaging the clutch there was not enough power causing the engine to lug and cause the judder. Anyone else experiencing this? I thought 6MT was gonna be less complicated than DCT

Interesting. I had this when car was new. Now I have 10k on it and either I learned to drive it or it's gone. Right now no issues at all

Yup this happens to me too and I've been driving with a clutch since I was 16 Makes me feel a little better reading this post that this is normal.

So I think it's a combination of over-gassing it. Try just slowly releasing the clutch w/ no gas and the car will feel like a "normal" manual car.

I started doing that in heavy traffic.. There's almost no need to ever gas it in first unless you need to take off fast.

Agreed. I normally just release/depress the clutch slowly and the vehicle will begin to roll pretty easily. The F8X model has enough torque (and gearing) to propel our 3400lb vehicles without a problem.

Problem is back, this time its really bad but it seems worse the colder it is outside. Maybe the clutch doesnt get warmed up so it has a hard time gripping. Starts from a complete stop are the worst. Clutch just doesnt want to engage smoothly driving normally but when I get on it at a light its fine.

Not sure how to solve this problem. Maybe change of fluid?

Funny I noticed it today too. Relatively cold here (40's). Clutch even felt a little "sticky" between gear changes too. Pretty inconsistent and finicky clutch on these cars...

I've had this happen to quite a few cars I've owned. my current 325 beater does this.

you need to slip the clutch more and more gas. my guess is babying the clutch tends to build material on pressureplate/clutch/flywheel?

do a couple nice hard start from stop. no need to burn out just slip the clutch a bit more.

I sort of like this recommendation

still nothing after 400 miles

As Fast4d stated above, slip the clutch a little more and apply more gas. This tends to stop the juddering, at least based on my experience.

However, if the judder is already well underway, giving it more gas will not solve the problem and will actually make the judder more intense. In this situation I step on the clutch to stop the judder.

I’m experiencing this too, albeit a bit more frequently in the last few weeks or so. (I have a 2016 F80 6MT with 8k miles) It’s been a little “colder” the last week here in SoCal too, so I don’t know if it’s also temperature related? But coming from driving a 2004 G35 6MT for many years, I guess I’m used to noisy/clunky transmissions.

I’ve tried just releasing the clutch without any gas and at times it’ll judder more . I suppose I’ll just try giving it a bit more gas like someone mentioned above.

In any case, I’ll have the dealer take a look the next time I bring it in for service. Just sucks that, like others have mentioned before, the juddering is inconsistent.

I had a bad episode today going up my inclined driveway. It felt like the clutch friction zone was higher up on the pedal travel too because I got a nice lurch when I released the pedal all the way. The car will be fine for several days or so but once in a while this issue rears it’s ugly head and really bothers me.

Mine did this more when newer but at 18,000 miles on the odometer now, I experience it rarely. It's harmless. Just drivetrain mechanics and is normal for these cars.

[HPIA4v2]

I think I feel a very slight "shudder", ,"judder" or even "gritty" clutch feel, only on cold,
at an incline and slow clutch-out. I think it's worst on my non-M E92 335i than my current F80 M3.
But my E92 clutch is fine all the way to 70K with all that, so I am not going to worry until it gets really bad. I only have 800 miles right now.

I've experienced this as well; but i just wrote it off due to the twin disc clutch.
I have a triple disc clutch on the civic and the chatter is almost identical.

However under hard acceleration there's zero chatter. Which is another reason i just wrote it off to it being a twin disc.

The f80 probably feels cool as a cucumber compared to the G35. The G35 was by far the most temperamental manual transmission I ever heard of. I learned manual at 17 and this was my first car and I was drenched in sweat by the time I made it home from dealer (6 miles away ). The weather would greatly affect the engagement point and the resistance of the pedal. If I had been driving in traffic for a while the clutch would start sticking and not sticking. It would squeak of engagement....so many random issues; non reproducible. (This was on a transmission,clutch, and flywheel less than 10k.) This had made me an excellent driver of cars with temperamental manuals, but somehow a slightly longer learned curve with cars with very short clutches (miata).

Now for the f80....the temperature(maybe) plays a large factor in shifting IMO. The traction control will intervene behind the scenes. You are giving less throttle in cold. ...someones tailgating you so you do 1-->2 too quick.


I guess what I am trying to say is there is ~10% of the time driving the f80 where sometimes it feels like it is shuddering a tad between shifts(what would be a symptom of pulling the clutch to early on upshifts...not waiting for rpms to drop) Even happens with perfectly rev-matched upshifts which is weird. I can't put my finger on it, usually always happens with drastic temp changes throughout the day and humidity. Northeast

I pay it no mind now. In my experience with the G35, it is damn near impossible to reproduce the symptoms at the dealership, and will just cause distraction, frustration, and less enjoyment from your car. If problem becomes serious of enough take it to dealer. Other than that just chalk it up to "sports car". Nevertheless, when it is connecting for me, it is pure bliss driving down back roads,

I had similar issues on my E46 after I changed the stock clutch to a single mass.

Happy to say I'm not experiencing this on my F80

Have you ever experienced where the clutch seems to grab and so you start giving more gas and releasing the clutch faster expecting a full engagement only to be surprised by the clutch suddenly grabbing more producing a big lurch? That's what I experienced yesterday pulling into my driveway.

[Bahn360Photo]

newer cars have a CDV, clutch delay valve, this is what slightly delays the clutch engagement during light release. its annoying but it does save the life of the clutch with newbie drivers

[G35POPPEDMYCHERRY]

Hmm starting to maybe get a gist of what you guys are talking about.

Im used to barely giving it gas when taking off (not like 99% manuals because you would feather in more gas as clutch engages)

But when I try to drive it with more throttle on take-off it does judder a tad. Is the what everyone is experiencing.

In this car I find to barely give it gas and slip clutch in and then begin slowly giving power. Driving this car in 1st and 2nd gear smoothly is quite an art form sometimes lol. Cant tell if nannies make it better or worse

[GregW / Oregon]

This issue has continued sporadically for a couple years. In the past the dealer said, "can't replicate." Took the car in Tuesday for my final warranty/maintenance plan check as Thursday was 4 years. Don't have much info, but they're replacing the clutch. Parts have to come from Germany, so car is going to be there a while (330i Xdrive loaner could be worse)! They are also replacing the Dinan exhaust for the 3rd time due to squeaking valves.
