Now, it is the washer jets' turn.

The current situation seems to be of indefinite duration. Engaging in various small-scale employment opportunities.

Upon first use of the washer jets, it has been observed that the liquid is being dispensed in a weak and inconsistent manner. I lack the financial resources to bring it to an authorized dealership. Upon doing an internet search, I saw that some filters need maintenance and cleaning.

Furthermore, I came across a suggestion from another individual advocating for the use of vinegar as a means of filling the tank. Is there any veracity to the claim? Has anybody attempted it?

Upon removing the washer pump, it will be seen that the combination seal/gauze filter is obstructed by a buildup of sludge.
I used a high-pressure water jet to cleanse my bottle thoroughly, afterwards attending to the cleaning of the filter. Following this, I adhered only to a singular brand of screenwash.

Thank you, is it readily accessible?

Could you perhaps clarify the specific section you are referring to that need cleaning? The eBay listing has the genuine BMW windshield washer pump grommet strainer with the part number 61667006063.

Indeed, it is the white portion.
The position of the component in question on E6X cars is not readily recalled. However, on E9X vehicles, it is situated inside the driver's wing and may be extracted after removing the wheel and arch liner. It is reasonable to presume that the same placement applies to the 5 series.

If it is possible to remove the tank and thoroughly cleanse it.
The removal of the black residue proves to be challenging using other means.

Upon opening the bonnet, I am able to visually see the uppermost portion of the bottle. When a torch is placed next to the bottle, it becomes apparent that the surfaces of the bottle are coated with a substance that appears dark or black in color.

Is there an effective method for cleaning the bottle without necessitating its removal? For example, might bleach be considered in this context?

[AbdulBMWi3]

One may attempt to engage in such activities; but, the subsequent process of extracting or eliminating the substance, regardless of the outcome, remains unclear.
It is advisable to eliminate the washing bottle.

I attempted many methods, including the use of drain cleaner, but unfortunately, I could not get the desired outcome.
Additionally, I detached the pipe from its connection to the bonnet and lengthened it in order to facilitate pumping into a bucket.
Ultimately, it was a competition involving tanks.

[AbdulBMWi3]

I had apprehension on the matter. Was the process of removing the tank time-consuming? How was the cleaning process conducted after the device was turned off?

After removing the bottle, it is recommended to use a few spoons of baking powder dissolved in warm water for effective cleaning. A bottle brush of satisfactory quality will effectively restore the inside of the object to its original condition.

It is advised to refrain from using the baking powder combination for the purpose of cleaning the pipes. The presence of foreign matter may obstruct the flow of gaseous substances inside the jets.
