Just got an F11 530d se touring, bought at 8 months old, 8000 miles, changed from previous shape 525d touring. It's generally a lovely car.

I'm having slightly annoying problems when slowing to a halt, particularly in town traffic. Gearbox seems eager to change down as speed drops so car jerks very slightly on each down change, then around 15 - 20mph ish, the efficient dynamics kicks in increasing the retardation, instinct then is to ease brake pressure slightly but then ED drops out so you have to increase brake pressure again. As most of us do, I pride myself on smooth driving but this is making it very difficult. Car been into dealer who say nothing wrong. has anyone else had similar experience?

Thanks,

Mike

Have a 535d and it is nothing like you describe. Auto-box (also the 8gear HP8 box on the 530?) blips the throttle on downshifts so there should be/is no jerking, also my box doesn't shift back early when retarding (on the "normal/comfort" setting). Modulation ok as well. Braking is jerky when using crusie control/stop & go function though. Certainly sounds like something is not in order with yours?

Thanks for your feedback. Yes, same 8sp gearbox. It's strange in that in normal driving there is almost zero engine braking then just at slow speeds it all starts to change behaviour. Dynamic control is always left in normal. Will try dealer again

Cheers.
