Well I rejected Safelite's offer of Fuyao glass.. I now have a local glass shop we've used before installing a PWG windshield next week. I'm hoping this may resolve the wiper issue.

Well, I spent some time today, caught in a slight drizzle on the way home. If anything would cause the wipers to squeak or chatter, this was enough to do it.

I've paid particular attention to this, remembering all the discussion here. I even muted the tunes to check. But the wipers are as quiet as can be.

I can't imagine that my car dealer changed the blades before I bought it in March, 2018. If so, then it means these are likely OEM blades from its July 2015 build. They should be chattering like crazy by now (5 years later). But no.

At least I'm lucky at this one.

I wondered as well because my wipers were always quiet and worked great, I would use alcohol to clean them regularly, but they lasted two to three years. Then I got my wife's car, night and day, they would skip, squeak and generally were absolutely miserable. I never used automatic because it was annoying, I knew something must be wrong as my other 212 was wonderful, I took four hours and Koenigstiger's wiper adjustment directions,I would get it in spec at the top of the arc and it would be out at the bottom, then in spec at the bottom and out at the top, I finally got both in spec after at least 30-40 cycles, then they were ok, what a battle! I had to do the same to the passenger side! Now they are almost as good as the 12. It was very frustrating and time consuming so I feel for those with this issue.

If silicone spray on the blades seems to quiet down the chatter, then why not change them out for silicone blades themselves? I believe I read over on the GLE forum of a user using a silicone spray wipes on the rubber and it quieter them down noticeably for a decent amount of time.

Anyone try these yet? Says they’ll fit on the 212..

Well, those are inserts and I believe the 212 uses beam-style, which may be available in silicone somewhere, others have suggested they are, Some have fixed this issue with all manner of coatings, others have gotten new glass, Other competent people have not had as much luck adjusting the wiper arm angles, for me it got better, I do on occasion use Meguires ultimate liquid which I believe is not a carnauba wax, I don't actually apply it, I just wipe the windshield and windows with the wax towel I used on the rest of the car.

1. The Michelin ones from costco ...inexpensive and work perfectly.
2. I clean all my windshileds with a "detailer" spray. I've used mcguires which works well, but now use Griot's which is even better. The "detailing" spray leaves the glass (like your paint finish) super slick. I've used it on every car in the family for years ...it's worth the little extra effort, IMHO.

I guess I should have mentioned. My wipers do not squeek or chatter. And I've done NOTHING to see this performance... NOTHING at all. I wash and rinse the windshield when I wash the car. That's it. Nothing exceptional.

I've never liked these aero wiper styles, because I've read no end to complaints here, and on other auto forums. But at least mine are behaving at present.

pierrejoliat

Well, I like them a lot, it's been ten or fifteen years since I've had to reach out the window and "slap the wiper" to get the ice off, as you probably remember! My 12 was the same quiet, no chatter, full wipes no problems. my 13 was a different story.

LILBENZ230

Silicone blades do not solve this issue.

@pierrejoliat - do your 2 cars have different windshield suppliers?

Based on my experience, it is factory glass by Saint Gobain. My car ended up with a FUYAO windshield and that solved the wiper issues immediately. I was never able to solve them myself on this car or my previous Mercedes, and neither was the dealer - though they tried.

Also, every loaner I've had in the past 5-7 years has done this. It's ridiculous that Benz can't get this together. It is not the blade style wipers that are the issue, our Macan has those and no issue. Also my 2005 W203 had them (facelift) and my W211 had them, also no issue. It's whatever glass Mercedes is using for the past several years just does not seem to agree with the wipers. It's a complaint you'll find widespread on every sub-forum here. And most of us lack the tools and expertise to spend hours adjusting the angles. They should just work correctly from the start.

Your car might as well be a vampire as much as it never sees the sun...lol
No sun = no sun damage

DFWdude

Can't possibly be a vampire, as I seldom drive the car at night...

I drove it 2 hours this morning while running errands to 3 stores. I put up my windshield "The Shade" at all stops, but of course that didn't protect the wipers on the other side of the windshield.

August in N.TX was the rainiest in years. Sept has already passed rain records.

BTW, some of you write your wipers were horrible on initial delivery as new. Can't be much sun damage
on a brand new car.

DFWdude

So, this got me curious. I just looked, and my windshield is OEM Saint Gobain Sekurit.

On its first visit to the dealer for a warranty replacement of the Burl Walnut wood, my service advisor told me as I retrieved the car, "Looks like you got a good one." Didn't think too much of it at the time, but now I think I understand.

bmwpowere36m3

Our '11 E350 came to us with a replaced windshield and MB wiper blades... prior owner serviced the car entirely with MB. No issues with chatter, streaking or squeaking. In the past, if throughly cleaning the windshield and wiper blade edge didn't resolve the issue, then replacement of blade/insert did.

nota_amg

Those are refills for the "non-contured" wiper, if you were to have them. These are what you want if you're after a "silicone" OE replacement(they are silicone impregnated rubber, not pure silicone):
https://www.ecstuning.com/b-piaa-par...set/9706860kt/
I used to have regular real 100% silicon wipers on my old diesel beetle beater. Never had an issue with them in 5 years and over 100k miles. I bought them on clearance at Walmart of all places. Can't buy them in any store now, not near me anyway.

nota_amg

You know I just like givin' you grief!

DFWdude

I know... No worries.

I'm just post-whoring my way from 2,984 posts to 3,000 by this weekend...

LILBENZ230

I've tried silicone blades.. they were worse, not better, than Mercedes blades in terms of chatter. It's not sun damage as this occurs with new or used blades as well as on new cars. My dealership demonstrated this happening on brand new W222s sitting on the lot. This was after multiple repair attempts on my 2014 W204. They adjusted blade angles, replaced the blades over and over again, clayed the windshield, stripped the windshield, polished the windshield, replaced arms.. They tried everything. They chattered regardless of what they did, and they were miserable every time it rained the entire time I owned the car. It damn near prevented me from ever owning another Mercedes.

I had hoped my W212 would not suffer this, but it did. Not quite to the same extreme as the W204, but until the factory glass was replaced, it was still a noisy chattering mess at low speeds in light rain. I never brought this to the dealer's attention with this one. Partly because I already knew they were not going to be able to fix it and partly because I accidentally broke the factory windshield before I had a chance.

Replacing the factory glass immediately resolved it. I'm still running the same blades as I had with the factory glass. My windshield no longer has the Benz logo on it, but I'll take that as a compromise for the silent smooth wiper operation my car has now.

This has been a sore subject for me for years. You're very lucky if you don't have it, but for those suggesting easy/obvious fixes - no. It's not nearly that simple. Given that the cars chatter even with various aftermarket blades of different brands, I believe something is fundamentally flawed with the wiper system on modern Benz cars. I recently had a 2020 W205 loaner.. the chatter/skipping is still happening on the new cars.

pierrejoliat

I wondered as well after reading your posts. No both cars have the original windshields by St. Gobain, both the same part nos. too. I remember my 03 S500 doing this but I took it in at 500 miles or so and got it back fixed for the next 13 years. My 02 E320 had one wiper, never got that car's wiper to work well, changed it every three months until I traded it in on the 07 S550.

mbMJDude

I have not had any problems either. I have the original St Gobain glass and original (or OEM) blades. I have 32k miles on the lovely brown beauty. My build is October 2015 - maybe the very last builds somehow got the combo right?

DFWdude

My car was built July 21, 2015.

LILBENZ230

My car is an 04/2015 build, but I spent a rainy weekend with a 12/2015 build Selenite E350 on an extended test drive before I bought my current one. It had the issue, and I don't think you'll get much later of a 212 than a December 2015.

Also, the 213s do it. Mercedes still has not got this right. At this point, I don't think they ever will.

S-Prihadi

Believe it or not, my drive in big rain only occured 2 days ago..... ever since I got the car in May 2018
I read thru all of the frustration on this thread. I feel you.

Is my wiper skipping ? YES.
Which portion of the blade skipped the most, the bottom one, or 40% of the lower part.

TESTED METHODS............
I cleaned windshield using alcohol - DONE

Did I use WD-40 on my wiper blade rubber ? NO WAY
Was the windshield waxed ? YES, but I cleaned it well with the alcohol when I suspected the wax could be the cause, like how fading away Rain-X caused jumpy-skippy.

Wiper blade is new - DONE
Got a new one in June 2020, genuine MB. How old the stock kept by MB Indonesia ? I don't know.
Is the wiper super clean this MB one ? Yes very very clean, no lines and spotless............... but it skipped like crazy at high speed setting.

Did I adjust the wiper incident angle - NO , too much trouble and I can't yet verify if my wiper incident angle is wrong

I tried buying both the Hella CleanTech and the Bosch AeroTwin, but Bosch no stock. So the Hella just arrived 5 hours ago , just installed and tested.
https://www.hella.com/cardriver/asse...s_HELLA_EN.pdf
For my car it is the 24" one. Thailand made.





Hella give 5 adapters. My car uses the 3B-2 , see video below.

Not tested in the rain yet, but tested with water splash and dry running on the windshield for 5-7 seconds after water cleared ........... no skipping
The strong points are :
01. Graphite coated rubber, so it has its own lubrication
02. Stainless steel insert at the rubber blade, so more even pressure on the glass surface of windshield.
I hope when big and long rain comes, the Hella stay smooth no skipping.

How much I paid locally for the Hella CleanTech? US$ 15.20 for 1 pair, excluding cheap shipping. Dang, i will buy 3 times a year from now on.
How much my MB one cost locally ? 500% of the Hella.




NOTE, I checked USA Amazon and there Hella number WBU24 has no R ending. I think the R = Right Hand drive

Dang, indeed, no R is for Left Hand Drive car, like USA and most of Europe. I guess it is the need of the aero-foil shape of the wiper.

Hope this can end your skipping problem Gentlemen.

END OF REPORT

Excellent post, as always, my '12's wipers and all previous Benz's I had no wiper issues, but my '13 was bad, I checked the angles and they were off by a lot, took many cycles between bottom and top position and a lot of patience, eventually I got them in spec top and bottom position and they are much better now, I did not have the factory Jig, so I used carpentry and machinist gauges to set them, it worked.

S-Prihadi

Yes, I downloaded the 3 docs you re-posted from Mr K..... thank you.
However my car is Right Hand Drive and the wiper mechanism is opposite of a Left Hand Drive car, and it is located almost center-line of the V-6 bank and not as a nice to work region of a Left Hand Drive car.
So I must remove really a lot of stuff just to follow step 4 & 5 & 6 of ADJUSTING WIPER SYSTEM ar82.30-p-6400-01cw , so buying new much more slippery wiper blade seems a better option

pierrejoliat

That doesn't sound like the Prihadi I have come to know! Actually I think that the arm angles of the wiper arms were the culprit in my case so with a machinists angle gauge with built in level I went back and forthwith the wiper arms up position and down position until I got it in spec top position and bottom position, I remember about 18 cycles of this per arm to get it right, I did 4,5,6 but I think the Arm angle at both positions was key!

Glad to see yo posting, Was worried, My sister in law lost both her parents to the virus last month and she mentioned it was really bad there, they wouldn't let her come home for the funeral.
