Does pre-LCI E90 have hill-hold function?

[easy]

Hi,
Any bros know whether our pre-LCI E90s come with hill hold function - that is the feature which aids in moving off without slipping backwards when car is stopped on an upslope.

Depends on gradient. Too steep still slip.

When I'm alone in the car, it will not slip back when start off on steep slope. Don't know if this is truly hill-hold or just the normal torque creep counteracting gravity. Haven't tested when there are passengers. True hill-hold should detect extra weight and make adjustments accordingly to counteract increased weight.

A true hill hold is 1 that has electronic parking brake. Torque converter can only do so much to counteract the slip.

I'm guessing most modern applications of hill-hold are paired with e-parking brake, but is it not possible to incorporate it with manual handbrake?

Definitely not. There would be coordination issue btw AT & parking brake.

Why not, quite a few BMW with manual hand brake has hill assist, eg 1M
