Does unauthorized windshield washer fluid additive damage seals?

Hello!

My two windshield washer nozzles for the headlights are probably leaking... and need to be replaced (128 EUR).

My workshop believes that the problem is likely due to a cleaning agent additive from a hardware store. This additive may contain alcohol, which can damage seals in the windshield washer system.

Is this a myth, or is there actually something to it?

Regards,
Felix.

Note
If windshield cleaner with antifreeze is not available, denatured alcohol (the alcohol content must not exceed 15%) can also be used. It should be noted that at this concentration, the antifreeze protection is only effective down to a maximum of -5°C.

Well, my girlfriend has a Skoda Fabia, and we had some issues with it.
'similar' or 'something similar' We had deposits in the hose leading to the front nozzles.
According to the expert, it's likely a combination of products from a hardware store, specifically antifreeze.
...and was likely due to the cleaning concentrate that I added.

I've been wary of ultra-cheap products ever since, at least.
I can definitely imagine that it could be effective when combined with other substances.
because there are 'interesting' side effects.

Yes, it's also known that some cleaning products don't mix well and can cause clumping.

Generally, you shouldn't mix different cleaning products. In the household, this can cause real problems (like chlorine gas!), while in a car, it will just clog the lines.

For vehicles without a strainer in the fuel filler neck, it is recommended to install a fuel filter between the pump and the windshield washer nozzles. With a bit of luck, you might find a cheap filter that consists only of a strainer, otherwise, a regular paper filter will suffice.

'For about a week now, my right side vent on my Passat Variant PD AJM (model from the 2000s, manufactured in 1999) hasn't been working properly.'

Does anyone know if it's possible to verschandeln them, and how to expand them with minimal effort?
The funny thing is, the left button wasn't working properly for a short time before, but now it's working again!

And if a replacement is needed, is there a new version available?

By the way, the windshield washer reservoir has a filter insert, but it could also be due to the winter washer fluid additive!

I only found information about the Michael II from the Golf (2 numbers) under the 'nozzle' category.
Does anyone know if they fit and what the price is?

Golf:
Unheated spray nozzle, part number 6E0 955 985.
Heated spray nozzle, part number 6E0 955 986.


So long

"I'm also aware of the problems. My Golf has Xenon headlights, and unfortunately, that also means it has the nozzles. Since my car comes from the Netherlands, there's also an issue with the winter package: the seat heaters and mirror heaters work, the windshield washer nozzles are heated, but the headlight washer nozzles are not. Because you have to use the lights more often in the winter and verschandeln the windshield more frequently, there are problems up front, as the nozzles tend to freeze, and you risk damaging the entire mechanism when they're forced to operate." Therefore, I (found an unsatisfactory solution) and disabled the headlight cleaning system in the winter by modifying the hardware.

You can get replacements more cheaply from a company in Soest or Lippstadt (I need to find out the exact name, something like "Tunit" or "Tuneline"... something along those lines). They sell the parts individually, as they somehow obtain them from Hella (which is based in Lippstadt).

Really not satisfactory ... In the summer, nobody needs it .

That was also the reason why I decided not to get the winter package with the heated seats, due to the numerous reports of problems with the SRA (likely referring to a specific system or feature). Stupid forced combination !

I think the SRA is brilliant, especially in the winter.

I have the standard version with the horns, without that hub mechanism.

These items have never been frozen before.

How do those ones with the lifting mechanism work?

Best regards, WarLord.

Well...

Basically, it's like a hydraulic cylinder, but the piston rod is hollow and has the spray nozzles at the top. And a small spring pulls the whole thing back down when the oil—or rather, water—pressure is gone.

Have you ever disassembled children's toys?
