Screen Wash Reservoir Level Sender Unit – Restore Accurate Washer Fluid Monitoring
This screen wash reservoir level sender unit is
designed for the classic Porsche 964 and Porsche 993 models. It monitors
the washer fluid level inside the reservoir and communicates with the dashboard
warning system, ensuring the driver is alerted when the fluid level falls too
low.
Fits:
Diagram ref no 6
Over the years, the original sender units can fail due to age, internal corrosion, worn float mechanisms or electrical degradation. When the sender fails, the dashboard may continuously display a low-level warning—or fail to warn at all—creating both inconvenience and a potential visibility hazard during poor weather conditions. Replacing the sender restores reliable fluid level detection and proper operation of the washer system.
What the Screen Wash Level Sender Unit Does
The sender unit:
- Detects
the washer fluid level inside the reservoir
- Triggers
the dashboard warning light when fluid is low
- Ensures driver visibility by prompting timely refills
- Prevents
pump dry-running, which can shorten pump lifespan
- Integrates directly with the washer system wiring harness
This small but critical component keeps the washer system functional and reliable.
Why Washer Reservoir Sender Units Fail
Typical failure causes include:
- Float
mechanism swelling or sticking due to age or contamination
- Internal
corrosion from moisture exposure
- Electrical
contact wear, leading to intermittent signals
- Cracked
housings, allowing fluid entry
- Heat
cycles and vibration, degrading internal components
- Build-up of washer fluid additives, causing float resistance
Symptoms include false dashboard warnings, no warning despite low fluid, erratic indicator behaviour or complete sensor failure.
Why You Should Replace a Faulty Level Sender Unit
Replacing the level sender ensures:
- Accurate washer fluid monitoring
- Restored dashboard warning functionality
- Improved driving safety in wet or dirty conditions
- Prevention of washer pump damage
- Reliable operation of a system essential for road visibility
- Preservation of originality and functionality in 964/993 classics
A new sender unit is a simple but essential upgrade for maintaining the practicality and reliability of older Porsche models.
