Audi VW Brake Bleeder Screw - Genuine Audi VW 4M0615273A

Product Information

A brake bleeder screw is a small valve located on each brake caliper or wheel cylinder that allows air and old fluid to be purged from the brake system during servicing. By opening the screw, technicians can bleed trapped air, ensuring the hydraulic system is filled only with brake fluid for proper pressure and braking performance. A functioning bleeder screw is essential for safe, consistent braking.

• Difficulty bleeding brakes, due to a clogged or seized screw.
• Brake fluid leaks around the screw threads.
• Soft or spongy brake pedal, if air remains trapped because of a faulty bleeder screw.

About Genuine VW Audi

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VAG parts box and find an OEM branded part inside, simply with the addition of a VAG logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
