Hi... i have recently bought a 1999 328i and it has rain sensing wipers, but what do the different settings on the 'knurled wheel' do? It all works.... when it rains, it wipes, but when I turn the wheel, it seems to make no difference- any help would be appreciated!

not sure, i was wondering the same thing too....did u get a chance to read the manual yet ?
Yeah, I did look at the manual, but it just says 'turn the knurled wheel for different settings'.... but it all seems to work the same way as far as I can see??? It doesn't seem to make any difference, it still works the same way! I haven't had a chance to drive the car in very light rain.... then you may be able to tell.....

Ah excellent.... but which is the most sensitive setting.....? You would think that as I live in England I would of had ample opportuntiy to find these things out in the rain- but I haven't yet!

btw I have a 2000 323i with sport package
Visually you can see the rain sensor. Look at your front windshield where the rear view mirror mounts. The rain sensor has a purple tint where it's normally black. This is the infrared eye that measures the amount of moisture on the windshield.
Here is a desription of all the positions for the wiper lever:
0 - Wipers retracted
1 - Intermittent mode or rain sensor (up one)
2 - Normal wipe
3 - Fast wipe
4 - Brief wipe (push down on the lever)
5 - Cleaning windshield (pull lever towards you)
6 - Rotary dial for control of the wipe interval or the sensitivity of the rain sensor
You move the wiper arm up one position (up one position from the off position), and that in itself should activate it. If you start the car when it is in this position, if you turn the wheel on the arm and that will activate it!
