OVERVIEW
Genuine VW/Audi brake fluid reservoir cap seal
893-611-347 is the individual seal for the assigned brake-fluid reservoir cap arrangement. It is cataloged separately from the cap, fluid-level sender and reservoir.
The listing supplies one seal only. Match the original cap and sealing profile before ordering, particularly when the cap has previously been replaced with another design.
Technical details and supplied quantity
- Manufacturer part number: 893-611-347; compact reference 893611347.
- Brand: Genuine VW/Audi.
- Component: brake-fluid reservoir cap seal / gasket.
- Application: the original cap sealing location assigned this exact part.
- Quantity: one individual seal per purchase.
The cap, sender contacts and reservoir are separate components. This seal is also distinct from the reservoir-to-master-cylinder grommets and the gasket between the brake servo and master cylinder.
Common reasons to replace
- The original cap seal is missing.
- The seal is split, distorted or otherwise damaged.
- Inspection identifies deterioration that prevents the correct cap seal from seating properly.
- Reservoir-cap servicing requires replacement of the assigned separate seal.
Inspect the cap and reservoir sealing surfaces as well. A damaged cap, reservoir neck or fluid-level sender requires its own repair. Brake-fluid loss must be traced to its actual source; this seal does not repair a leaking hydraulic line, master cylinder or caliper.

Installation and service guidance
Follow the factory procedure for the affected reservoir and cap. Keep the opening and surrounding area clean, protect nearby surfaces and prevent contamination of the fluid. Inspect the cap's seal seat and the matching reservoir surface before fitting the replacement.
Seat the correct seal in its prescribed location without twisting or damaging it. Use only separately specified repair materials and avoid introducing unsuitable lubricants or debris into the reservoir.
Reinstall the cap according to the applicable instructions and confirm correct seating. Check the fluid level and any disturbed level-sender connection, then complete the prescribed inspection and brake-system checks before returning the vehicle to service.
