I know exactly what you mean by the lag, it drives me insane. I feel like im driving a 70HP SUV.
I personally think it caused by two problems: 1.-The engine has almost no torque below 2000 rpm and the transmission always wants to stay at the highest gear and below 2000rpm 2.- The computer in comfort mode has a delay or input lag built in on purpose. I have tried flooring it and the revs will not move at all, as if the computer assumed grandma just floored it by mistake. I swear any car, a honda civic, camry or any old people car is more responsive than this "sports" SUV in comfort mode. |

I have started experiencing the exact same delay from a stop/start, for example at stoplights or when slowing down to enter a roundabout. I’ve had the car for exactly a year and this started happening at around 10,000 kilometer on the trip meter.
It’s as if driving a manual and being REALLY bad at using the clutch to find the biting point...

Yeah, I get their desire... but it just makes it even worse when you cant predict when it will lunge. For me, I would rather know when to expect the leap in power vs it being so random. Now, I have to push and just hold my head back waiting for it to go. But I get it... and I did feel the same thing in the X3M. Its the main reason it isnt in my driveway right now.

I had the same complaints when I first got the car and these two things made a big difference for me:
#1 set up sport individual to be your default drive mode with these settings: - engine: sport - tranny: comfort - suspension: comfort # 2 Use the transmission sport mode early and often! I frequently slap the trans into m/s to get a better throttle response when needed and it works really well in conjunction with step #1 Just a guess, but I think comfort mode skips 1st gear and then sometimes thinks too long about shifting into first when you give it throttle. Using m/s with the settings listed above forces the car into first gear when at a stop so you get a much better response off the line. I often do this while rolling as well and it will immediately downshift most of the time. It feels great when you are preparing to overtake someone, no delay just GO. |

If you search for throttle body reset you may have a solution. I’m airborne on my phone so can’t post a link, but it seems the tranny and throttle might learn to be a granny but you can reset it back to normal. Worth a try.

I highly recommend coding sport individual to be your default drive mode and playing with the settings. Try different configurations for a day or two at a time and I think you'll find something that meets your needs. |

I often think it’s be nice to be able to push one button on my 4 and have all systems in full sport mode. Also, is there a Sport and Sport individual mode? |

1. 'Torque: 500 Nm (51 mkg / 369 lb-ft) from 1520 rpm to 4800 rpm'. So max torque from 1520 rpm....! 2. It's comfort mode, try putting it in sport. You tried flooring it and the revs don't move at all? I'm guessing this is an over dramatisation, if not have you tried turning the car on at all? I had a Honda CRV previously and I can assure you it was NOT more responsive than this 'sports' SUV in comfort mode. I find it amusing that over 2 pages of complaints no one from the UK has joined in. I guess everyone from the other side of the pond is used to big V8's producing comparatively little power but masses of torque. For some reason no matter which forum you go on there is always someone complaining about lag in throttle response. I had the same experience on the Audi S3 forum. Numerous people berating how poor the throttle response was and how dangerous it was pulling out in to traffic. I never experienced any of this and at no point did I find myself in a dangerous situation. Can I speculate that maybe some people buy this car expecting it to be super fast because it has a decent engine in it and therefore it should be able to get out in a gap which isn't really suitable? Then they complain that it should be able to make up for their poor judgement because they have just put themselves in that situation. This is not aimed at anyone I just don't get it. My car is quick for an almost 2 tonne SUV, but I certainly don't think I'm in a sports car. |

To my mind, Comfort mode, by design, completely deadens the throttle, making it very soft, so that your passengers aren't getting kicked around every time you hit the throttle. It's not turbo lag, or lack of power, or anything. The throttle just dampens your inputs in comfort mode for the comfort of your passengers. I've always partly overridden that in my 4 by putting the car into S on the transmission lever. Going full sport on both transmission and mode can be a bit aggressive (holding on to gears a little long) if I'm not driving alone. Looking forwards to see how this all behaves in the X3 30d straight six vs my current 4 series 30i 2L turbo. Hoping it's smoother.

To be fair, Comfort mode whilst nice for passengers, can feel a little unresponsive at the throttle. Which the OP is assuming is turbo lag, when it's a throttle damper. And nobody wants full on sport all the time as it can hold gears a bit long and annoy your passengers. It would be nice to be able to tailor how aggressive the throttle damping is in Comfort mode to hit a sweet spot, if you don't have a lead foot. A sort of Comfort Individual mode, if you like, in addition to Sport Individual. Moving the gear shifter to S compensates somewhat though.

My standard driving mode is "Sport" with the gear shifter over to the left. I find the throttle to be much more responsive, but the transmission doesn't hold the gear as long as it does in Sport Plus.

Sport Individual can serve this purpose. See post 26

Something worth trying in Comfort is to initially use a small throttle opening just to get the car moving then open the throttle much wider. Or use Sport.
This issue has been around for ages with other BMWs.

I had big throttle lag in one of my other cars, and the Sprint Booster fixed it:
