Stutter when idling in drive
i have about 25,000 miles on a 14 'S and whether in C or S/+, when creeping forward in drive I have a stuttering but when the mct is fully engaged the acceleration is smooth.
Do I need a new mct clutch or clutch re adaptation?
i figure these clutch plates wear out eventually

What do you mean by stutter? Are you talking about jerking or rpms go up and down when starting from 0? My car just hit 20k. It happens to me when its cold out. When car is warm this doesnt happen.

When I let off the brake and let it move forward with idle it shudders a bit before the mct is fully engaged and the rpms are steady...
this is different than the jerky s or s+ starts ... this is if I slowly let OFF the brake to allow the car to idle forward and I feel the pulsing/shuddering forward motion of the car

I am pretty sure my '14 with 30K does it too... I also pretty sure it goes away once it hits normal operating temps (temp numbers are no longer blue) AND I do believe I have read on the forum that it's a normal issue with these cars... unless you are referring to something entirely different.

my issue is with the brake still applied and allowing the car to break from a stop and creep forward ... it pulses forward until I totally let off the brake and the mct is fully engaged ... still not pressing down on the accelerator ...
my issue happens at all temps ... never had this for 22k miles
thanks for feedback and your ideas!

i recall the jerky acceleration was associated with just that... acceleration with pressing down on the throttle

...and then of course the next time I drove it, i noticed it. A pulsing wobble. I've always kinda felt it, but never thought anything of it.
He said they all do that and he was wondering if mine was the same. Go figure.
FWIW this is not the same as when the car struggles to engage the clutch plates when it's freezing cold outside (mine is certainly struggling under these freezing temps, so I'm avoiding driving from freezing cold nowadays)

Funny you say this, a was speaking to a friend of mine who owns a workshop and the first thing he said about my car was 'do you get that jerky wobble when you put it into D?" and I said not that I've noticed....

I do not get jerky acceleration. That feeling of the car "pulsing fwd" after you have come to a stop by simply letting go of the brake is what I have in my car... and... either I have gotten so used to it by now that I don't notice it.... or it does actually go away when the car is warm.

It is a form of gas savings algorithm put in most German cars nowadays. Clutch readaptation should help but honestly it comes right back after a few thousand (I have had that done on my car a couple of times if I remember right).
It is the clutch disengaging and re-engaging when you are idling in Drive (or immediately after you shift into drive). A 2014 E63 I drove some years back also had the same issue. It is more of an annoyance than a problem, see below.
Happened a lot in my wife's very old 528i which was a pure automatic. The software seems much better with the newer BMWs cos I have not felt anything like that in her most recent 535i or any of her previous but newer BMWs. We got rid of that 528i with 157k miles on the odometer and never a transmission issue on that car.

I guess we got lucky then lol. Its basically the clutch or torque converter delay in re-engaging when you are letting off the brake. Keeping it disengaged may be saving 1/100000000000000000000 mile per gallon lol. However if you take into account that you get zero miles to the gallon at a stop, anything helps I guess

A cold start and into drive dragging the brakes I felt it..Never noticed that before. Once the car was warm temp out of the blue and would go into 1 gear. ,dragging it felt smoother. In C mode I felt the shake again when warm... did not try M...to me its on when the car is in 2 gear first gear seem smoother...
