My rear window wiper always judders across the screen on the return wipe - and it gets very annoying! I’ve switched blades from Bosch to Valeo and this made a big reduction, however it 70% of the time will judder across the screen on the home wipe. Is there any way I can adjust the retention spring to make it push less harshly on the window? Or are there any brands of blade to use which is silent?

AFAIK the only adjustment you can do is to bend the metal arm the wiper mounts onto.
And give the glass a bloody good clean, it may be the glass that's the problem.

@Harrihealey02; Agree with Andy on cleaning the glass. You may find you have quite a lot of contamination on your rear screen in the form of small tar spots that may have also transferred onto the blade rubber, and a ‘dirty’ screen and blade rubber won’t be good for silent operation.

Claying the rear screen to remove contaminants, and then giving the glass and wiper blade rubber a really good clean with a good glass cleaner would definitely be worth trying before changing the wiper blade.

The front wipers on my vehicle did exactly the same, so annoying. VW also said make sure the windscreen is clean but come on. Anyways, the issue was resolved when I had my vehicle booked in for 45 000KM service and they replaced the "worn" wipers, never had a problem since. Same goes for the mooing of the brakes while reversing, once replaced all was well again.

Sounds a bit daft but try cleaning them with some WD40. It helps clean the grease and muck of the blades.

Unless I'm reading it wrong, the same wipers for 45000KM....?
No wonder they were juddering, they must have been completely fu....

I guess the weather is less favourable your side of the world compared to sunny South Africa
In truth I mentioned it to the dealer within weeks of owning the car and all they would do is apply some cleaning solution to mitigate the judder. I also travel many KM's per day so to get up to 45000KM's didnt take long at all.

I'd guess sunshine is as bad for the wipers as excessive use in rain is.
When I watch car restoration programmes, the damage the sun does to cars is incredible.
Cracked and faded dashboards are not something we have to worry about here!

I have that problem with brand new bosch blades (changed thinking that the problem came from the factory blades).
I think that the motive in my car is the glass cleaned too much... With all my cars in the past I always cleaned the glass with a glass cleaner for cars and a water repellent treatment.

The only solution for me is spraying washer fluid to lubrificante the wiper.

I think it must be something to do with the car glass and wiper tension which causes this issue. I had a VW golf 2021 courtesy car which had horrendous judder with factory Bosch blades. I cleaned the wiper and glass and still hasn’t helped. I’m going to have to buy another brand of blade until I find one which doesn’t judder, currently using Valeo Silento which is the best so far.

Bosch as standard?
Pretty sure they're Valeo on the Polos.
Don't suppose it matters, whichever brand it is they will be the cheapest version they can muster up.

Had the same judder on our Polo and tried everything and nothing worked. Bought some Bosch Aerotwins and the judder went immediately.
