Hesitation during acceleration 535i
F10 535i with 1500 miles.
I have noticed a hesitation/lag during acceleration. When at a cruise speed around 40mph and I quickly press about 1/2 down on the accelerator to gain speed there is a slight hesitation/lag before the engine kicks in. If I slowley press on the accelerator the speed increase is smooth. Does anyone else have this issue. Another item....when does the blower kick in. |

Maybe try with the tranny in sport (manual) mode so it won't downshift on its own just to see if it's really just tranny lag. If so, there's not much you can do about it other than apply the gas smoother. Quote:

HI. Suffer from the same issue. I just think it's the car being in 7/8th gear at 40 then of course it has to drop say 3/4 gears to pick up once the foot is down.. it isn't one of the best bits of the car i have to say.. but i think i can live with it

Thanks for the info uktivo. I tried it at a steady 50 and then a steady 60 today and still have the hesitation.
When I press on the gas the rpm immediately revs but there is a hesitation before there is any increase in speed. |

I drove the 335 with N54 & 535 with N55. I have noticed that the N55 have more lag than the N54 engines. I noticed a delay of 300-400RPM. Maybe someone else can verify this.
