How to Use the Headlight Cleaning Function on Audi A4L?

Audi A4L headlight cleaning tutorial is as follows: 1. The headlight cleaning is a vehicle feature, similar to the windshield wipers, which sprays washer fluid onto the headlights and then wipes them several times. 2. First, you must turn on the high beam of the headlights by pushing the lever on the left side of the steering wheel forward. 3. Operate the lever by pulling it towards yourself (the same action as cleaning the windshield), and then the headlight cleaning function will be activated. 4. It should be noted that when the headlight cleaning function is activated, the windshield cleaning function is also activated simultaneously. Similar to windshield cleaning, the headlight cleaning uses washer fluid instead of other liquids in the vehicle, so you need to pay attention to the level of the washer fluid.
I've been driving an Audi A4L for several years, and the headlight cleaning function is very convenient to use. After getting in the car, first ensure the engine is started, then operate the wiper lever on the steering column. Normally, a gentle pull is enough to clean the windshield; but to clean the headlights at the same time, the headlights must be on, then quickly pull the lever twice or hold it down for a longer time (this varies slightly by model year—my 2019 model requires two quick taps). At this point, the nozzles will spray cleaning fluid to wash the headlight covers. Be careful not to let the cleaning fluid level get too low, as this reduces effectiveness. During each maintenance check, I ask the mechanic to inspect the fluid level. If the headlights are too dirty or covered in mud, it can affect lighting safety. After cleaning, it’s best to wipe them dry with a soft cloth to avoid water stains. Avoid overusing this feature to prevent frequent refills. Audi’s original cleaning fluid works best, but regular windshield washer fluid can also be used—just avoid strong chemical additives. Overall, it’s very simple and takes just a few minutes to complete, keeping the headlights clear for safer nighttime driving.
As a DIY car enthusiast, I find the headlight cleaning design of the Audi A4L quite ingenious. After starting the engine, keep the headlights on (either in auto or manual mode), then operate the wiper control lever next to the steering wheel by quickly pulling or pressing it twice, and the nozzles will spray fluid for automatic cleaning. I regularly check if the nozzles are clogged and gently unclog them with a needle if necessary. When the cleaning fluid runs out, I refill it with genuine replacement fluid or neutral windshield washer fluid into the reservoir under the hood. Avoid using cheap water substitutes to prevent corrosion of the coating. After cleaning, ensure there are no residual liquids on the headlight covers; if there are, wipe them dry to maintain brightness. The key to DIY is patience—avoid damaging the electrical components. Simple tools like a small cloth and fluid reservoir make the process easy and cost-effective.
