My new 08 535 has this chatter problem real bad. Driver's side is terribly noisy going both ways and it's downright embarrassing. Dealer says they can't duplicate, so I am going to try this fix myself.
Question, where along the arm do you apply the spanner and twist? I would assume closer to the blade?
Perhaps I should just demand that the dealer order me in a replacement arm?

yes I am also confused about where and how to apply the spanner application.
I do have a chatter on the downstroke - the BMW mech did bend the wiper but it was more of a 'horizontal' bend along the length of the wiper instead of a twist, as a result the chatter seems to have got worse

Guys,
If your wiper(s) is just noisy on EITHER the upstroke OR the downstroke (not both), then there is probably an easy, simple fix that will take a few minutes to do.
Imagine your leading edge of the noisy blade. What is happening is that the edge is trying to "dig in" to the screen (an exaggeration, I know, but it is an illustration). If you twist the wiper arm (not the blade) so that the blade has a reduced angle of attack to the screen, this will (in 90% of cases) cure your problem.
Get yourself a small adjustable spanner, and some rag or card to protect the paint on the wiper arm.
If your noise is on the upstroke, look along the arm, from the wiper end to the pivot. Put the spanner on the arm and twist the arm anticlockwise - about 10 degrees at a time.
Try your wipers - you'll probably have to only do it two or three times.
Obviously, if your blade is noisy on the downstroke, then twist the arm clockwise.

Perfect diagnosis and exact remedy - whether a new BMW or an old Ford this situation/problem has been around since they put windscreens/windshields on cars.

I don't know if RainX has been improved in the past 5+ years but when I had rainX applied to my windshield I always got this build up occuring on the windhiseld which caused my wipers to jump and stick..
Since then I have never applied RainX on my cars.

Who applied it? I have been using Rain-X for years and never had that problem. You might want to have whoever applied it RTFM

Well, I don't exactly have any chatter until I got smart one day and spend some money changing out the old wipers. While putting them on, I found it difficult and spent 20 minutes instead of the usual 5. After that the chatter began. I thought it could be the washer fluid addictive that I added recently but now coming to think of it, it could be I myself bending the wiper arms when changing out the blades... I will update if that is the case. very soon. tomorrow morning. Its 12am MN here.
