Hi guys, my rear wiper has started juddering really badly on the upwards sweep. When it returns (comes down), it's perfect, so it's just when the wiper sweeps up. It started a few weeks ago, and as far as I know, nothings damaged it and it looks brand new still ?
I've thoroughly cleaned the rear glass with Autoglym fastglass as well as Isopropyl alcohol, and even change the wiper to a Bosch aerotwin to no avail.
My guess is that the rear wiper arm is perhaps slightly out of shape and allowing the wiper to sit on the glass at an awkward angle ? Anyone ever had this and any ideas please ?
Also, whilst I'm at it, on the front windscreen I have a lot of what looks like run marks which have suddenly appeared after bonfire weekend. They are invisible to the eye until you wet the windscreen or use the wipers when you can then see them, and they disappear as the windscreen dries. I'm thinking it might be residue from firework fallout as my next door neighbour had a lot of fireworks in his back garden and my car sits on the other side of the fence. I've tried the same as the rear screen i.e Autoglym fastglass as well as Isopropyl alcohol, but you think you have shifted it, until you wet the screen and they appear again. Once again, anyone any ideas please as they weren't there a week ago.

Mine drives me batty!
I've not tried cleaning or replacing it though - I thought it probably was just the rubber worn out or gone hard.

A Bosch rear wiper was just over £5 from Eurocarparts, using one of their discount codes, no issues since.

Absolutely, the OEM wipers are next to useless compared to the Bosch ones. Once you swap you will wonder why you waited so long to do it.

Think the OP has already done that.
Sootchucker, mine is the same. When it was in recently at the dealers for the headlight they even referred to the judder on the health check. Need to try and sort it.

I'm glad its not just me!

Just replaced the rear screen blade on my wife’s Fabia Estate, as that started to judder after about 12 months. A new OEM blade fixed it. I thought just over a year was a bit short, but you don’t know all the history of even a new car - how long it’s been standing out in the weather etc.
Now, though, the blade on my 8 month old GTI has started juddering. On the first occasion, after a squirt of washer fluid failed, I stopped and gave the rear screen and blade a clean with spray screen cleaner, which I believe is mostly white vinegar. That worked for a while, but it is now back to juddering, unless the screen is properly wet. Thinking of giving it all a thorough clean, but not holding out much hope.
I noticed the runs on the front screen last night, but I haven’t tried anything yet.

My NEW Bosch rear wiper judders.
-
Just a thought, I keep a coat of G-Techniq C2v3 on my glass and the blades front and back run smoothly. The rear blade is the original one from new and no issues.
-
Glass sealants I’ve found are always a gamble as sometimes that can add a judder I didn’t have before if the glass isn’t that wet.
-
I've got the Gtechniq on both front and rear and I'm still on the original factory wipers. Three years old next month and and still wiping perfectly.
-
Rear wiper on my car was juddering as well. I polished the glass with some glass polish and then fitted new bosh blade. No issued since then.
-
I’ve found that using Gtechniq to be the best for both front/rear glass. I’ve tried plenty of different ones over the years and only been spot on with Gtechniq.
Definitely worth a try from personal experience.
-
Just need to be careful which Gtechniq product is used on the front screen as it can cause worse judder than before.

Reading through this thread, since about the 12th October my rear wiper has started to judder & the front have been revealing residue/streaks like someone else posted. Prior to mid October both were perfect & had been for over a year since they were installed. All blades are Bosch, & I use meths/water & Fairy/hot rinse water to clean mine. I previously suffered 4yrs ago the dreaded front wiper judder even after trying G-techniq top glass coating & other wiper blades etc. the solution was to cut the glass with ceranium oxide glass cutting polish from car pro..(Ceriglass)
So why is it now causing problems? My car went into the dealership for cambelt & MOT on the 12th & stayed outside overnight at the dealership until I could pick it up the next day. When I picked it up it had a heavy amount of condensation water on the outside as it was cold overnight My car is otherwise garaged all the time.
The fact that others are having the problem & only just recently leads me to believe that there has been a nasty acid rain cloud from Europe/Russia which has deposited loads of pollutants which has attacked the glass & roughed up the surface at a microscopic level. This same rough surface at manufacture is what causes the original wiper judder.
Solution:- cut the glass using Ceriglass...

I think its probably something to do with the back end sucking up a lot of road dirt, which gets onto the glass and then ground in by the wiper. Scratched glass being the problem?
The rear diffuser on the Mk7.5 is definitely better than the Mk7 in so far as I only get a light dusting of road dirt on the bumper, unlike the Mk7 where it was like a sandpit but it still chucks it up there.
However, the Mk7 didn't seem to get the wiper mangled like this, so maybe the dirt stream is impacting the glass more somehow.

I've had the car 5yrs now & NEVER had this problem with the rear wiper, even with the rear end coated in masses of dirt. The car was clean before it went to the dealership & they did not "wash" it either as were told not to (& they obey)…& the fact my otherwise perfect & fixed front screen was now showing streaks/patches when the blade passes over & the streaks did not tie up with the blade means its something that has settled on the glass.
Basically who has problems just appearing or re-appearing & keeps their cars outside ?....

Mine is kept outside.
Its been doing this for easily 6 months, maybe longer now...
