We have had torrential rain all day but the official 928sRus tester has gone AWOL.
Probably watching NASAR or something like that 8>)

I'm not noticing much of a difference between the A&B's. Currently running the B wipers. I was able to wipe a few drops from the screen on the way home yesterday. Typically I have a stuttering issue, but thus far it has not happened with the B.

I'm not AwOl Rog, I was watching the race tho. Have to go out for some "supplies" in a few.

SeanR

Just took a nice drive in a down pour, well, they work and I like them. Can't tell much of a diff between the A & B's except the stuttering, so I'm keeping the B's on the car.

Had A's on for 8 months and had no issues with them either, much better than the regular bladed wipers.

So a related question is, do they make one of these suitable for the REAR wiper? None of the ones I've seen have the side mounting hole and I'd kind of like mine to match!

SeanR

Flint, don't know about that some of us down here did the rear wiper delete. Alan did it a few posts up.

Hey Rog, when can I be the test mule for the 928'srus Super Charger?

Alan

Here is what the 24" on the rear looks like

Also one of the side pin modification:

I took the hinged cover off - pulled out the pivoted plastic part - drilled out the pivot pin and filled the space with a 3/8" Lexan spacer. I drilled this through and countersunk the pin from the old blade into the new one. Fits sugly and works perfectly. I like the 24" length - bigger still would fit too...

Well there you go. To hell with what Bosch says. Looks like the concensus agrees with Icon 20" front "B's" and 24" rear "B's" Thanks for this thread.

The above comments are in no way, approved by Bosch®, or its dealers. The opinions of the above persons do not reflect on Bosch®, and Bosch® is not responsible for people doing what they think is correct in the real world. Then again Bosch® has to put out this kind of stuff so the rest of us won't sue them over $20.00 wipers.

I ditched my Bosch Icons (installed by PO) today in favor of Bosch regular blades, because the Icons were scratching my new windshield. That plastic housing in the middle of the blade leans right over and touches your glass, thus scratching it. Now can anyone recommend a glass polishing compound, or a procedure to fix my windshield?

4 years on Icons and have not had anything like you described.

ROG100

It is very important that you use the 420B Icon for both front blades. Sounds like you had 420A on there maybe.

Bill Ball

And I'm at 4 years with the same "A" pair. I've never seen other blades last this long.

420A's fit fine (now 20A), as do B's-- the only difference is slightly more curvature to the B's. Bosch says 20A on the driver side, 20B on the pass side, and that's what we use. And they work well, Pacific-Northwest certified. Neither A's nor B's have any tendency to flop over or scratch, although any wiper will scratch if run dry on a dirty windshield.

Glass can be polished, what you want is Cerium Oxide powder (mix with water to make a paste) and a hard felt polishing pad to fit a low-speed polisher or a drill motor. It is messy, masking helps with the cleanup.

safulop

Cerium Oxide powder -- thanks for tip.

I realize that running wipers dry can scratch, but I have never done that. Furthermore the contact between the plastic central housing on the wiper and the window glass was plainly observable with the wipers just sitting there, and the scratching was totally confined to the width of that plastic housing. It's pretty much an open-and-shut case as to what caused it.

Based on Alan's above information (thanks Alan!) I finally updated also my rear wiper to a 21st century one, being a Bosch aero twin AR24U (as I was not able to find any Bosch Icon wiper blades locally, but these appear about the same).

Hereby a few pictures of how I did it:
- Top left: use a dremel (like) tool with cut-off wheel so to get the old pin + old plastic top cover out from the old wiper surroundings. The old plastic top cover is of key importance, as it is a bit bended when in place and thereby provides a more than a large amount of friction so that the pin does not go anywhere.
- Top right: use a 5mm metal drill bit to drill out the pin from the new wiper blade from both sides as well as a making a hole in the new wiper blade plastic cover, and put the old plastic top bit in place (as per the picture). Then insert the pin and put the new wiper plastic cover on it's place. Note that I also had to remove some plastic from the underside/inside of the new wiper blade plastic cover, so that it fitted smoothly over the old plastic top cover.
- Bottom-left: the whole assembly together. I tried the force as needed to get the old pin out (as I do not like to have the rear-wiper blade to fly off whenever driving high speed on the German autobahns), and it will need really a heck of a lot of force. So it is fine this way.
- Bottom-right: installed, done.
