Clogged windshield sprayer

I have searched a lot and all the available videos are for other BMW models that do not have a similar mechanism to my 2014 X1. Can anyone guide me how to take out the windshield washer filter and clean it? Last time the clogging happened BMW dealer quoted me $120 to have it replaced (ridiculous, right?), but they did it for free as a courtesy. I have used windshield washer fluid ever since to avoid this problem, but it seems to be back. Here are some photos of the assembly if it makes explaining easier.

Clogged windshield washers seem to be a seasonal thing, and this - winter coming - is the season.

I make my own WW solution of distilled water (to avoid water spots) and methanol-denatured ethanol (wetting agent, solvent, anti-freeze) ($15 gallon)

The alcohol is a de-naturally for biologics like the slime biofilm that I believe clogs WW strainers, pumps, tubes, and nozzles.

Do not probe the nozzles with hard sharps as they are precision moulded fluidic oscillators and easily destroyed.

Hi,
Had a similar problem recently and ended up having to replace the washer jet. It's an easy job but the part is not cheap £45 (at least not in the UK) but still much cheaper than the quote from your main dealer.

To remove the unit:

1. Rotate black collar on T that connects the unit to the hose by lifting it slightly. Hose should then simply slide off.

2. Press in the clip on the electrical connector and pull off.

3. The unit is clipped into the underside of the bonnet. Push it towards the windscreen and use something flat to pry the back end out.

4. Refitting is just the reverse.

Hope that helps.

Thanks. Could you advise on the part number? Is it #1 here by any chance?
Also, the rear washer is working fine. If the strainers for rear and front share the same tank, doesn't that mean that my problem is also from the washer jet like yours?

Will definitely go with distilled water this time.

Yep, that's the part.
I also had an issue with the pump for my front washers so once I sorted that I knew for sure the washer was kaput as well.

If you have fluid coming from only one of your front washers then it would be safe to say your pump is fine and it's just the washer.

Otherwise you may want to check the pump. You should hear it 'hum' when you activate the washers.

Thanks. Fluid isn't coming from either of the front washers, but I hear the humming.

In that case you could have a blockage at the pump. If you remove the pipe from the first washer in the series and blow down it, you should hear bubbling. In that case you can be confident you need to either clean or replace the washers.
If not you need to rule out a blockage in the pipework and probably pull the tank and pump to inspect.

The pumps have a screen on them, which means if you use anything that has additives it will be clogged. You have to take off the passenger front wheel, liner, and then you can find the tank. You'll have 2-3 pumps there, depending on your options. There is a reason RainX has a lawsuit against them for certain cars.

Protip, at least some windshield fluids will etch concrete.

I make my own WW solution of primarily distilled water (<$1/gallon) and methanol denatured-ethanol ($15/gallon) concentration that varies with the season. Now, winter, about 1:3 ethanol:water.

Distilled water to avoid water spots and the ethanol as antifreeze, wetting agent, surfactant, solvent. Still using CPO OE wiper inserts.

The Rain-X class action was for sensor failures and has been dismissed with prejudice. The original plaintiff repaired his problem for a reported $150. (ClassAction.org)

I would be very interested in a citation to a windshield washer fluid that will etch concrete.

The density of methyl alcohol is less than water so it's going to stay on top but the filter is at the bottom. Not sure how beneficial the alcohol would be.

ALL Alcohols are fully miscible in water.

Because of the strength of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount. Starting with the four-carbon butanol the solubility of alcohols is starting to decrease. After the 7-carbon heptanol, alcohols are considered immiscible. The alcohol solublity in water can be observed below. The amounts are in mol/100g of H2O at 1atm and 25oC.

Alcohol solubility chart

Name Formula Solubility
Methanol CH3OH miscible
Ethanol C2H5OH miscible
Propanol C3H7OH miscible
Butanol C4H9OH 0.11
Pentanol C5H11OH 0.030
Hexanol C6H13OH 0.0058
Heptanol C7H15OH 0.0008

Do you think this is ok?

Also what ratio of this to water do you recommend?

I tried and failed to see what is the denaturant. With that caution, it is probably OK to use in your WW reservoir and system.

I donít measure the concentration that I use. In winter weather it is convenient to add the alcohol to a half empty jug of distilled water for the better Ďspoutí. If the window spray crystallizes ices then I add more alcohol. The weather is warm now and I have spent a couple of months in the south and I can still smell the alcohol when I spray the windshield.

The cost of that brand product is twice what is shown for equivalent product with other brands on AmaXonís compare page.

This product is available at WallyWorld and is a whole lot cheaper than your link even if you mix half a bottle with a gallon of distilled water:

That is the brand that my hardware store carries and that I use. I buy it by the gallon, most recently $15 per gallon.

There's always this BMW product for less than $3 each online. It's concentrated; you dilute it to the level of freeze protection that you want (-25F to 33F):

Vodka or Everclear (100% grain alcohol) works too!
