    Its a stop-start issue.
    Should the engine restart once it senses you ease off the brake? So, you take your right foot off the brake and apply it to the throttle and you get a lurch?

    I know the Mk 7 system works in better ways than my 3 yr old car but I have found that if I just change pedals too quickly when stop start is engaged it does bound away.

    Solution is just to ease off the brake enough for the engine to restart but not allow the car to move and then when traffic moves or lights change you an accelerate normally.
    As I mainly drive locally I can anticipate the lights pretty well.

    I think it is basically as you ease off the brake and the engine restarts, the next part where the transmission re engages is the tricky part. It has usually jolted before the accelerator has been touched. So yeah you can do a slow ease off the brake to try and control it to an extent.
    If i do it with auto hold it is trickier as the engine is re started by the accelerator. I haven't thought of a method to smooth that way out.

    If you give the brake pedal a good prod, it will start the engine once again. This is useful if you know the traffic lights are about to change in your favour, or you can see a gap opening in the traffic. it doesn't sort the co-ordination issue conpletely, but is useful if you want to avoid any issues in tricky traffic conditions.

    For me, most of what everyone has said were all issues in the early days of ownership, but my technique has improved to the point where it is a non-issue.

    Easiest way is not being lazy and turn off Auto Hold As it defeats stop start on my car I never use it.

    But then its flat around here so dont really need it.

    Easier just to keep foot on brake and then ease it off to let engine start as lights change and then it pulls away normally.

    Maybe the mk7 is different in operation as if I hold the brake on hard the engine stays off Have to lift foot for it to restart

    Foot off brake

    car starts

    foot transitions to throttle - no clutches engaging

    foot depresses accelerator pedal 5-10%

    clutches still not engaging for a few seconds (this is a hint its about to happen - as usually it'll start engaging the clutchs into a "creep" mode after a second.

    Clutches engage violently and throw the car forward - no change in throttle input - car then continues moving relative to initial throttle input.

    So its not like the ecu is picking up a quick and large accelerator input and trying to get away in a hurry, it just lurches, and then slowly crawls away at the speed id expect in relation to the throttle input i have given.

    The next few times it does it (start/stop activation), its flawless! And moves away from rest gently, just fine.

    But then again, out of nowhere, itll bite the clutches hard and spear me forward with startling force once again.

    Nope. If your foot is on the brake and you lift it a small amount, my MK7 restarts.

    But you dont need to lift off all the way for this to happen.

    Thats exactly what mine does so to get off the mark this is what I do.

    If at the lights, watch them,

    Lift foot slightly off the brake,,
    Engine starts, wait for lights..
    Lift foot off brake pedal, wait the few milliseconds for car to start to roll,
    Hit the loud pedal as required. Gently for a start, Get it rolling and then hit it up a bit.

    Same for in traffic, but never let it sit on the clutches as you would in a slush box.

    Yeah, that's what i try to do but a lot of the roads im on are 2-way, or simple stop-start traffic - so i dont have the luxury of traffic foresight.

    Most of the time i cant preempt what triaffic is doing ahead, therefore i wait for traffic to properly get moving before coming off the brake. Otherwise you're essentially riding clutches.

    If you lift off the brake far enough to start the engine but keep the car still I dont think the clutches engage till your foot comes right off
