Why You Shouldn’t Use Water Only
Using plain water in your BMW’s washer reservoir is not recommended. Here’s why:
- Water can freeze in the lines and nozzles in cold weather
- It lacks cleaning agents to remove bugs and oils
- May lead to mineral deposits that clog the jets
Always use a fluid that’s designed for automotive washer systems.
How to Fill Windshield Washer Fluid in a BMW
- Open the hood and locate the washer fluid reservoir cap (usually blue or black with a windshield symbol)
- Unscrew or flip open the cap
- Pour in your washer fluid slowly to avoid spills
- Fill until just below the top of the reservoir
- Close the cap securely and shut the hood
Most BMWs will display a warning when the fluid is low—don’t ignore it, especially in winter.
Pro Tips for BMW Windshield Care
