 "Turn off" hill-assist on manual trannies?



This might seem like a dumb question, but I currently don’t have the opportunity to experiment with this feature on a test drive. I’m wondering if there’s a quick way (i.e. much faster than the 2-3 seconds it’ll take to do it on its own) to defeat the hill-assist now present on the manual E90s. I’m not sure how it’ll work out, but in places such as the steep inclines of San Francisco, I can imagine times when I would much rather prefer the guy in front of me to have this feature instead of me. Often times, it’s easy to notice a rookie or tourist in the city by how much they roll back starting off on steep hills. When I notice someone in front of me struggling too much upon advancing, I quickly step into the clutch to roll back with him, coming to balance my car within six inches of the guy behind me, granting all possible space to the front car. I reckon the occasional slight wear of my clutch is minor compared to the scratches on my front bumper. Two-three decades ago, when there where a lot more manual drivers, one could frequently witness this phenomena: an out of town driver not knowing how to manage his manual car on hills, and 2-3 experienced city drivers behind him, who’d immediately roll back in unison giving the rookie a full car’s distance to get his act together (upon failure, there would be a colorful exchange of words…). Anyhow, would double clutching, or a momentary shift to 2nd before reengaging 1st allow one to begin rolling faster? Now that I think about, parallel parking on hills will also be cumbersome if one needs to wait 2.5 seconds to begin rolling in the opposite direction of the gear once the clutch goes in, short of actually shifting. Among my long list of why I prefer a manual to an auto, quicker parking into tight spots on inclines is one of them; I hope I don’t have to give it up.

The feature ONLY activates if all the following are true:

a) You are at a complete stop
b) The clutch is pressed
c) The breaks are pressed
d) The car is in first gear

Then, when you lift your foot off the breaks, the feature will activate. The length of time it stays engaged seems to depend on the steepness of the hill. (Note that if you are facing down-hill, the feature activates if you're trying to back up the hill). I think it's simply brilliant and would help you A LOT with parking due to it working in reverse as well if needed.


So, if any of the above conditions are not met, the feature doesn't activate, so you can take your pick as to how to make it roll. Also, as soon as you start moving forward (in the forward-driving uphill scenario), the feature is disengaged. So, for example, if you start moving slowly forward then notice someone rolling back, you can do your clutch slipping without worrying about it activating. I think I would love it in a place like SF

Shift to neutral. So in theory a double clutch should work.

Although it's a neat gimmick, I didn't particularly think it was a great feature, while driving my e90 around. The clutch takeup is much better than the car it replaces, and it beging to grab nice and progressivly, with the pedal almost right off the floor.

Well, it is not a great feature if you like using your hand breaks on steep hills or if you like rolling back a bit at first before you go forward (which is inevitable on some hills no matter how fast the clutch grips).

Should you ever need to use the hand brake to stop from rolling back?
