m3s don't have cdvs, but bmws in general are hard manuals to shift. Hydraulic clutch, dual mass flywheel, heavy heavy pedal....we're not talking Honda civics here.

My e36 and e46 both have rather light clutches, but the e46 is a pain to change gears at low speeds when driving slowly.

@@mariuszanfir2298 you could have a problem. Have you changed the trans fluid or trans/shifter bushing? Could be worn bearing or gears too.

@@thepincushionman7063 Thanks for the input, but is nothing related to the transmission itself. It's the dreaded CDV. My car is a 99 EU, so I assumed it doesn't have one. Little did I know that is actually has one, I was shocked to see it there. It's still in as I did not have the time to remove it. However, the clutch-stop mod is fantastic. It alleviates the problem almost entirely. Best "mod" I did to the car. And it also looks more OEM than the OEM clutch stop :)

Lol, different strokes for different folks I guess. I'm taking mine out next weekend as I hate it, can't seem to get a nice shift from 1st to 2nd unless I drive like tortoise and wait for the revs to drop enough to match 😒 But to be fair i'm gonna be drifting mine so I don't want any driver AIDS 😂😂😂

I'm going through that problem right now with my car. Daily commute, that one hill climb, rather steep and leads to a roundabout so cars have to wait and car's behind look at me like i can't drive, but the clutch delay valve doesn't allow the car to go without putting in a large amount of acceleration just to squeeze the clutch and snap it into release it makes the car jerk forward weirdly because its done whilst the car is stationary on a steep hill. Its crap sometimes because its embarrasing when you have passengers. Even 1st and 2nd is surprisingly so bad most times it always involves my car doing a baby jerk trying to keep its balance standing up and its very embarassing and takes a lot of fun and energy out the driving experience for me. It doesn't happen all the time i just want to be able to stop and go how i want but I'm apprehensive of the gear ratio between 1st and 2nd if it will be smoother. Can you give me more detailes on the the difference without the cdv.

Hello devin

@@darkemperor418 You can try taking it out. If that doesn't help you can clean and reinstall the cdv. When it gets dirty over the years it functions poorly

@@danielinacar jheez I posted this 3 years ago I've got a merc now 😂

@@darkemperor418 Did you ever try anything with the clutch delay valve?

delayed throttle response? how do you improve that?

M. Hayes, no idea yet how to improve that, but I am busy investigating it. Seems a bug in the ECU software, triggered by some sensor that is not working correctly... Have to figure out what it is.

I am almost certain that the idle bounce and the throttle lag are related to each other, so if you fix the bounce, your throttle will probably also respond much better. Could you explain the bouncing idle symptom you are having in the winter? Maybe make a video of it? I am really interested in knowing about other cases... I get that you are from "down under", so making a video may be difficult since it is probably not cold enough anymore, right?

haha yeah its not winter here anymore, but the revvs just go high and low (bounce) when its cold on initial startup when the engine is still cold aswell. e.g: upon startup it will start normally and after initial startup it will idle at under 1000 and will bounce to over 1200 for about 20 seconds then idle normally. not sure if its just because it cold outside and the engine is cold too, or if there is a more serious problem like a vacuum leak or something

M. Hayes, it could always be caused by something like a vacuum leak, but in that case you should have other symptoms too, like misfires and check engine lights. I assume it is a manual car. Do you get bouncing idle when coming to a stop and pressing the clutch at traffic lights or similar? Or only right after starting the engine? Do you have more difficulties taking off in first gear with cold engine?

Sound advice

Chris Corpus you do not have the clutch delay valve right?

btentusscher it is not a fixed part of the fluid line. You can simply remove it and then attach the line directly (without any adapter) to where the valve was attached to before. Any mechanic should be able to do that easily once he takes a look under your car...

?

I think maybe I didn't put enough thread sealer on the flywheel bolts. Tryin' to cut corners by not buying new ones. Don't do what I do, lol.

50sKid lol yeah I get what you're saying. I had bought a new selector shaft seal. Only now I still have to put it in 😂

Clutch feel is going to be better, with that crap thing you barely feel something. Stupid idea from bmw.

I blew the cracked my cylinder head shortly after this comment

@@willk3807 lol what

So should i remove it?

@@Supremepikachu Absolutely! Its not event "the best mod" its a must do.

@@DJzSith so I'm curious because I have 240k miles on my car so the clutch has to be getting somewhat bad but this is what my car does exactly, slips when accelerating hard at all through all gears. I might remove it and see if it helps even though my clutch is probably worn as well

@@GPerformance710 definitely remove it and I would suggest replacing the clutch I did the stage 2 xdr clutch the pedal isn't much heavier than stock unfortunately I also had to replace the flywheel

What track is this at?
