Skoda Integrated Funnel Washer Fluid Cap Seal Ring Replacement
When you open the hood and see the rubber seal ring on your washer fluid cap looking cracked or stretched, you know it’s only a matter of time before every hard stop leaves a puddle of blue liquid sloshing around your engine bay.
TL;DR
The Škoda integrated funnel washer fluid cap (part numbers 6V0955485 or 000096706) is a one-piece rubber design that folds into a funnel . The seal ring is an integral part of this cap, molded into the flexible TPE material—it is not sold as a separate replacement item . If the seal is failing, the entire cap must be replaced. The good news: a new genuine Škoda funnel cap costs around £10–£25, takes five minutes to fit with no tools, and works on virtually every modern VAG vehicle .
Key Takeaways
- The seal ring is molded into the cap—you cannot buy it separately
- Replace the entire funnel cap, not just the seal
- Part numbers: 6V0955485 (funnel design) or 000096706 (Škoda Genuine Accessories version)
- The cap fits Škoda, VW, Audi, and SEAT models with the standard filler neck
- Made from TPE (thermoplastic elastomer), resistant to oil, fuel, and temperatures from -40°C to 90°C
- No tools required—the cap simply pushes onto the filler neck
- The funnel design prevents spills that a separate funnel would cause
What the Integrated Funnel Cap Actually Is
Škoda introduced the integrated funnel washer fluid cap as a Simply Clever feature, first appearing on the Scala in 2019 . The idea is brilliantly simple: instead of a rigid plastic cap that you remove and set aside (and inevitably drop), the entire cap is made from a flexible rubbery material that turns itself inside out into a funnel when you open it .
The whole mechanism relies on the shape of the material, not hinges or springs . When you close it, the funnel folds back down and the cap seals against the filler neck.
This is why there is no separate seal ring to replace. The sealing surface is a molded lip on the cap itself. When that lip wears out—cracks, hardens, or stretches—the cap loses its ability to seal. The only fix is a new cap.
Why the Seal Fails
The cap lives in a brutal environment: engine bay heat, chemical exposure to washer fluid, and constant flexing every time you open it to top up.
Common failure modes:
- Heat hardening: The TPE material becomes stiff and loses its ability to conform to the filler neck
- Chemical degradation: Washer fluid additives and engine bay fumes attack the rubber over time
- Physical wear: Repeated flexing causes micro-cracks at the sealing lip
- Stretching: The cap can deform if it’s forced onto a mismatched filler neck
The result is the same: fluid sloshes out under cornering, or evaporates faster than it should.
The Fix: Replace the Cap, Not the Seal
Since the seal is integral, your only option is a new cap. Here’s what you need to know.

What Owners Actually Report
The VAG community loves this cap. It’s one of those cheap upgrades that makes a genuine difference.
On Opposite-Lock, an owner who fitted the funnel cap said: “This should be OEM on all vehicles” . They noted it costs £8–£25 depending on where you source it.
On The Autopian, the writer praised the design but warned about long-term durability: “a mechanically stressed hinge in an environment that will completely destroy the integrity of the plastic” . However, this criticism applies to the standard plastic caps—the funnel cap is made from flexible TPE that handles flexing much better .
On eBay reviews, buyers confirmed fitment across multiple models: “Fitted Golf 7 GT”, “Great fit on mk2 Tiguan”, “Used it to upgrade the cap on my VW T5.1 Transporter” .
The consensus: if your cap is leaking or the seal looks tired, buy the funnel version. It’s a five-minute job and you’ll never spill washer fluid again.
Always drive responsibly and follow local traffic laws. A leaking washer fluid cap won’t affect driving, but low washer fluid in winter reduces visibility—keep it topped up.
FAQ

A Quick Word on Safety
Always ensure the cap is fully seated after refilling to prevent washer fluid from spilling onto hot engine components. Washer fluid can be flammable in certain concentrations—keep it away from exhaust manifolds and electrical connections. Follow local traffic laws and drive responsibly.
