Information
Water reservoir filler neck cap
The Porsche Genuine OE Reservoir Cap (Part No. PAA955455) is an original factory sealing cap for the windscreen washer fluid reservoir. Designed and manufactured by Porsche, this component ensures a secure seal on the washer fluid filler neck, protecting the system from contamination and fluid loss. Also commonly referred to as a washer fluid cap, sealing cap, or end cap, it is a small but essential part of the vehicle’s washer system.
Fits:
Porsche 955 Cayenne 2003 - 2006
Porsche 957 Cayenne 2007 - 2010
Porsche 958 Cayenne 2011 - 2018
Diagram ref no 3
The reservoir cap seals the washer fluid tank filler neck, preventing dirt, debris, and moisture from entering the system while also stopping fluid from splashing or evaporating.
By maintaining a closed system, it ensures reliable operation of the windscreen washer jets, helping maintain clear visibility in all driving conditions.
Functions & Technical Role
• Sealing function: Prevents washer fluid leakage and contamination
• System protection: Keeps debris and moisture out of the washer reservoir
• Fluid retention: Minimises evaporation and spillage
• Easy access: Allows quick opening for refilling washer fluid
• OEM precision: Manufactured to Porsche specifications for exact fit and durability
Fitment / Position on car
• Fitting position: Front – washer fluid system
• Location: On top of the windscreen washer reservoir filler neck
• System: Windscreen washer / cleaning system
Cross Reference / Superseded Numbers
This part cross-references and replaces several related OE numbers: 1K0955455, 3Q0955455, 95552860700, 95552860701, 958955455
Although small, a missing or damaged cap can lead to:
• Washer fluid leaks or evaporation
• Contamination of the washer system
• Reduced washer performance
• Potential blockage of washer jets
Replacing with a genuine Porsche OE cap ensures proper sealing, long-term durability, and reliable operation of the washer system.
