I replied because you said that you thought that you "have some kind of problem on my dct gearbox". The behaviour of your car is normal. It is not normal for your friend's car to move when the brake pedal is released. Is he left foot braking and already has his right foot on the accelerator?
Thanks for your help, i will test again today, just to check him car

If I am not mistaken, the "drive-off assistant" will only prevent the car from rolling backwards when in D or S, but will not prevent the car to roll forward.

My driveway is on an incline and I always back up in the driveway (nose towards the street). After putting the car in D or S, the car rolls forward as soon as let go of the brake.

If I leave the shifter in reverse, shut the car off, and then get out and lock it, the light on the shift blinks. Does this happen for anyone else? What is this meant to indicate?

I assumed this was a warning of some sort, so I always leave the car in 1 and then shut it off so I don't get that blinking.

From manual:
Flashing display on the selector lever of the double clutch transmission
The actually engaged transmission position can deviate from the selector lever position in some situations. The display in the selector lever flashes.
Observe the display in the instrument cluster in these cases.

I don't know anything beyond that.

Thanks! That's interesting, because by that logic, it should flash when the shifter is left in '1', but goes to park right? Or maybe that's not the case because even though '1' is selected, the lever stays in the middle? Maybe I just answered my own question

So after driving the 17 m3 for few hundred miles, its still pretty confusing.

Is there any way for it to behave like an automatic when you need to inch forward into a spot rather than pressing the gas and hoping not to ruin your bumper. I'm pretty decent at hitting the throttle to get it but its just cumbersome when in my e92 manual all I have to do it let go of clutch slightly and gas.

Also I'm not sure why it happens I guess I am hitting the gear but all of sudden the car will go from d mode to sequential mode but will not switch gears, its led me to rev insanely high without switching gears. What is an easy way to stop this from happening? I have my m1 mod to be comfort all around, m2 is sports plus everything.

Also if i stop at the red light when I am at d1, and hit the gas the car has a weird jerk to it.


All in all the car is insanely fun to drive, just has these quirks which i am sure is all me.

I have yet to try a kickdown yet, most and i usually use the paddles to shift down to take over cars. Someone should make a video on how to drive this car properly.

Once you are full stop and in gear, you can give a light blip on the throttle and then stay off it. In a moment it should start to crawl forward (or reverse).

It will behave like a true manual in S mode. It will redline and stay there without switching gears. I don't think it will let you blow the engine though.

I have found (in my first few hundred miles) that you have to really ease onto the throttle lightly and stay there until you start to have some movement, then get on it, or you will get a lurch to start.

The ///M DCT is designed to more closely mimic the behavior of a traditional manual than an automatic, hence why it does not "crawl" when you release the brake.

You have to learn how to drive it and once you do, it works very well. When launching from rest, think of the throttle pedal as a combination of clutch and throttle. The more aggressive you are with tip in from rest, the more revs it will use you before releasing the clutch. At one extreme, if you just slightly tap the throttle and release, it will crawl forward (low speed assistant). At the other extreme, if you mash the throttle to the floor, it will almost redline the revs defore dumping the clutch (smokey burnout with DSC off). I find the most efficient way to for a smooth and speedy launch from rest is first to lightly tap the throttle to get the clutch to engage and then roll onto the throttle.

When in D mode, moving the gear lever to the right or manually shifting gears will default the DCT back in S mode. Further, if you have an M-mode programmed to S-mode, will also engage S mode if that M mode is selected.

From my experience driving with my 15' DCT, getting the car going forward in D1 does have a slight hesitation/roughness. If I switch to D2, it shifts much faster and you don't feel it. My car's software supposedly is updated around August.

The thing that really bugs me is using Sport+, D2/D3, and flooring the car, where it takes so long to upshift afterwards after I let off of the gas. I feel Efficient mode will tend to upshift faster. Just feels odd having that rev hanging at a high rpm after letting off the gas where in my mind I personally would have already upshifted if I was driving a true manual car.

I do appreciate the M DCT where you could theoretically still roll backwards after the brake hold wears off, so it feels like driving manual again.

What CanAutM3 said; drive it like a stick and use the throttle like a combo clutch/throttle. You could also try to put it in second and then inch forward.
I've never used low speed assistant, I just got used to the pedal...

...and I'm a fucking moron so it's not impossible is my point.

Just drive it in S-mode, problem solved

Lol. It's a euphemism for adding throttle.

Can also mean grabbing private parts...but not in this context

DCT Questions

Hi guys,

Really new to the M cars. Ive just picked up my F80 and have some questions on DCT.

Every time I put my foot down it bounces out of automatic into paddle shift mode, even at fairly low RPM. So I keep having to hit the DCT shifter right again - to put it back in auto.

Is this correct? How would do I keep it in auto?

That is not the correct behavior. It should not do what you described. Is your car used?
