That's fair. And I've always had fun on vacations with MT cars, even super underpowered ones (Peugeot 106 with it's inline 3 67hp was a blast to drive). I've just never driven one on a regular basis.

I’m curious as to the CDV delete for this model. E9x only required removal of a small plastic valve. F87 required replacement of the slave cylinder from an E9x. Hope the G is similarly simple.
Yeah, on my M2C I changed the clutch slave to a E90 M3 one and it solved the vague clutch pedal issue but then it also gained some funny noise when you engaged the clutch from a standstill/in traffic. I think for the G80 I'm not going to bother messing with it.

Well that would be awesome if that was all it was for sure.. Hopefully the service team.. figures something out..

I was actually talking to whatsyourforte and his still happens after alignment..

It's a really strange thing, because it feels assisted. Supposedly other people have had some form of reprogram to fix it.

It's def a quirky thing.

Until you guys figure out the holy triangle:

Ultimate clutch pedal
CDV delete
And get a short shifter(auto solutions)

You're basically out of luck.

This exact reason is why I went with the m4c
Yeah I reached out for the SSK from AS.. but he is pretty busy.. so not sure when he will be able to create.. which from everyone's reviews that seems to be the product to get..

When this happens is the safety ring button next to the hazard button still a green ring? I thought I turned mine down but all safety systems are turned on unless you do a long press on it every start.

No it's completely red. I kept making sure.. because I thought I was crazy at first.. I absolutely acts as if LKA is trying to assist but using the steering input instead of lines/etc.

It's only with quick movement of the wheel and releasing it too. It just goes directly in that direction pulled and then needs to be corrected back to center manually or else it would run you into cars/walls lol

1200 mile service is in the morning.. and I am about to tell them to keep it until it feels like an 80k car..

Not to mention.. this steering pull when lka is disabled is stupid

Ugh.. kinda mad.
Obviously, I cannot feel what is happening with your transmission and clutch. but it always seemed to me that FWD cars' clutches are different from RWD cars. Most of my driving has been on RWD cars or 4WD/AWD cars whose primary output has been the rear wheels, so that is what I am used to. Whenever I have driven FWD cars, the clutches always felt "grabby". (not a technical term, but that was the word I used.)

Maybe try to turn all systems off by holding button down and see if LKA still kicks in?

You can - I deleted my original post. I hope you mesh better with your G80 soon! Everyone should love their car after spending this much money on it.

I have driven a lot of manual transmissions over my time and I found the F87 to be one of the easiest to use of any in regards to clutch engagement and shifting as to me it would be perfect for someone to learn how to drive a manual transmission car. Basically the exact opposite experience of a Subaru STI that has absolutely horrible clutch engagement. I assume the transmission in the G8x is the same and maybe the clutch setup is different?

I have felt that way about all the MT BMWs I have owned: E23, E39, F32, F30, G80 (current).

Tempting as it is to say "yes", no, you are not crazy.

I'm guessing that like the F87 with the integrated CDV/Slave, you have to replace the sucker with an older design, like from the E9x chassis. Not difficult, but not particularly easy with the tight clearances, fluid running all over you while you do it and bleeding it properly afterwards.

I hated it too on my M2, but I'm starting to come to terms with it (the clutch). Basically you have to do what BMW wants us to do, which is go slow and take it easy. If you rush the shifts and pop the clutch, that CDV is going to delay (hence the "D") the engagement of the clutch to save the drivetrain. It's annoying, it's frustrating, and I hate the attitude of the manufacturer that thinks that they know what's best for us, when in reality it's just there to reduce their warranty claims.

As for the shifter, it's perfectly normal for a BMW. It's actually a lot better than the older cars, which had a whole bunch of side-to-side slop and could make you miss shifts on hard acceleration when the engine torque would twist the transmission. You'll get used to it.

Now, the steering. I concur that it is odd. I'm actually happy to see you guys complain, because I thought that there was something wrong with my car. Now I know that it's not just me (or it). My impression of what it does, is that once you stop moving the wheel, the assist is off. Then, as you start to move it, the assist comes back on. This results in a really odd feeling. It also tends to keep the wheel pointed wherever you left it, there's no returning to center without some help.

Annoying. I don't like it. I wish it was better. But I'm getting used to it, and now that (thanks to you all) I know that "they all do that" I'm going to quit bitchin' about it. But don't let that stop you all from complaining about it to BMW. They can tweak the software, and if enough of us mention it, they'll have a fix for it eventually. I hope.

Haha , well I know I am def crazy ... I reached out to BMW as well .. because I think the fix in the software would be an easy fix.. at least the bit when you completely turn off the nannies.. that signaling event shouldn't be allowed. So I believe that abrupt movement causes a signal being sent to engage some type of lane directional movement. Though the caveat being if nannies are off there is nothing to tell it to stop that movement. So I suggested that there be a kill command in place that when LKA is completely turned off that the steering input be dropped from monitoring of that system (which it should be one would have thought) . I tested last night on the highway for hours .. and it is a continuous guidance in that direction. There must be exact event triggered when steering/rack is moved in that manner that makes the system say " Oh shit steer in this direction" .. anyway I will see what BMW says.. if they would just let me see the event triggers in the software I could prove it lol.. I read signaling for a living pretty much..

For the clutch/shifter.. it's just really tough .. I mean it's like they got me by the balls.. I love the look/feel of everything else... but that clutch has me cursing out loud while driving.

LOL, let us know when BMW lets you take a peak at the source code. I used to be a programmer, so maybe I could make some suggestions.

Actually, I was talking with another manager here this morning about self-driving/automation in cars, and how neither one of us like it or trust it. I said, "yes, that's because you know too many programmers!"

OK, anyway... the clutch. The solution is simple, as noted above, just order the E90/E92 clutch slave cylinder. It's like $90 last I checked. Search the F87 (M2) forum if you want more info on it.

If you are a DIY/shadetree mechanic, you can do it yourself. I've removed CDVs in the past myself, and I am at best, an incompetent mechanic with many broken and missing parts after I do something. And yet I've done this two or three times, and the car still worked.

If you can't do it yourself, it shouldn't be more than an hour of labor for any decent shop.

The only way it's going to void your warranty is if the clutch fails, then they will likely refuse to cover it. The odds of a clutch failure is pretty low. Heck, if it does happen, just put the old slave in there before you tow the car to the dealer.

Like I wrote above, I hate it too, but I am getting used to it. I'm not going to change just because I'm lazy to do it and too cheap to pay a shop. And my biggest stock holding is tanking today, so I'm feeling sorry for myself.

I would do the opposite. Drive it aggressively and shift at red line or close. The harder you drive - the better it feels.
On some shifts blip throttle - release clutch at higher RPMs - let it catch at 2k - then rev to red line -shift.

If you're going to shift 1-2 at 2300 you might as well just eliminate it completely and start off in 2nd. The car has no issue with doing that.

I agree 1 - 2 blows, it often never feels great and seems slow. 1st just seems an odd gear ratio.

That said, a clutch stop made a massive difference, and 3rd in the 6MT is absolutely glorious. Taking that to redline you're not far off 100mph before you need to change. The car just comes alive.

Actually over 100, you can hit around 106ish at redline in 3rd, I've picked up a bit of experience with this messing with dragy over the past few days. In Mexico of course.

Also ran the mathematical calculations for each gear as well.

This is what I’m worried about. I did not like the gear shifts in the previous M3 as well. I saw someone said that Porsche is the same feeling. I would like to say no they are not the same feeling. The Porsche gearbox is way way better than the F80, E92 or whatever generation M3 comparable.

I don’t want to bash the new manual gearbox until testing it out but it will be a tough decision then to go auto or manual.
