OVERVIEW
Cover the original washer-fluid reservoir filler
1H0-955-455 is the Genuine VW/Audi washer-reservoir cap with an integral retaining collar. The blue molded cover closes the matching filler neck while the collar keeps the cap attached when it is opened.
A missing or broken cap leaves the washer reservoir opening exposed to dirt. The correct cap must match the filler-neck profile and retaining arrangement; it is not a pressurized engine-coolant cap.
Technical details
- Complete factory number: 1H0-955-455.
- Factory specification: washer reservoir filler cap with integral retaining collar.
- Design: blue molded cover with washer symbol, flexible connecting section and retaining ring.
- Quantity supplied: one individual washer reservoir cap.
One cap assembly is supplied. Reservoir, filler neck, pump, washer hoses and washer fluid are separate. Confirm the original cap number and filler profile.
Common reasons to replace
- The cap is missing or will no longer close securely.
- The flexible retaining section is broken.

- The cap is cracked or distorted.
Inspect the filler-neck lip and collar mounting area for damage. A broken neck may require a separate reservoir or filler repair. Check for debris in the reservoir before refitting a cap.

Installation guidance
Clean the filler area, fit the retaining collar in its original position and close the cap evenly over the neck. Avoid stretching the flexible connecting section or trapping it under surrounding components.
Open and close the cover to confirm secure seating and free movement of the tethered section. Check that the filler remains accessible and surrounding parts do not interfere.
