Parking sensors, do they work?
Discussion
I can't see to find my answe online very clearly.
I went for a test drive in a E91 330i M Sport, when putting the autobox into reverse I didn't hear any beep, I didn't really look at the dash/buttons at the time. I didn't reverse near anything to close either to most likely set them off.
So should they have beeped or something? When putting the auto into reverse?
Thanks!

On my e90 auto when you select Reverse it will change the sat nav screen to a picture of your car with lines at the rear to signify how close you are.
They only beep when you are within about half a meter of something. They work pretty well, but they are overly sensitive. So most of the time I get what looks like close on the monitor + audio signals, but when I get out of my car I still have 15cm of space to use. Better safe than sorry though!

I've owned an E91 since April,
Apparently the parking sensors are "intelligent" and don't go off if someone walks in front of them.
They come on automatically if reverse is selected, but not at the front if you're creeping up to something.
There is an on switch next to the gear selector for those hard of hearing.
If you can fathom out the Idrive settings you can probably change it to come on at over 50.
I'm finding the seat adjustments complicated...............

With a manual you can select reverse with electrics on and engine off, then walk round the car. (Engage handbrake first. Don't forget to select neutral before starting the engine.) Might work with an automatic too... though I suppose you could just leave the engine on.
If the beepers don't go beep, another option might be missing/broken fuse.

E91 has rear parking sensors as standard, with no option to turn them on/off. They only make a noise when you're near something. Solid tone indicates the least space you can open the boot from memory.
Reverse towards something like a bush, if you hit it before they go off, they don't work.
If you've ever reversed in to a parking space with something behind you and never heard them I'd imagine they don't work, they're fairly sensitive.

I've had 2 x E46 with rear sensors and 1 E87 with front and rear.
None beeped when you selected reverse only when you got near to something, then the beep gets faster as you get closer until the beep is continuous.
The front and rears only worked after you had reversed, but the fronts were still active until you had gone over about 10 mph then they cancelled (rear only ones just worked while you had reverse selected).
And all of mine picked up on pedestrians - they even tended to pick up on kerbs.
So always worked fine for me - well apart from the time I ignored them!

I don't know how ignoring pedestrians ever seemed like a good idea. Pedestrians are somewhat soft and squishy, unlike (say) a lamppost or a wall, so if you hit one with your BMW it's true that it's not a very big deal. And if it's a little pedestrian, say only a few years old, they're pretty small at that age, so it's even less of a problem! But I can't help thinking about the resulting mess. Who wants to have to clean that up? Not me, that's for sure! So I think it would be beneficial if the car could warn you when you're about to run one of those things over.
