OEM Electric Parking Brake Button 4K0927225B for Audi A6 S6 RS6 A7 S7 RS7

The Electronic Parking Brake (EPB) Switch (Part Number: 4K0927225B) is an essential interior control component engineered specifically for Audi C8-generation vehicles. Designed to replace worn, scratched, malfunctioning, or non-responsive parking brake assemblies, this switch restores full operational safety and reliable electronic handbrake engagement. Manufactured with high-precision internal contacts and premium wear-resistant surface materials, it guarantees factory tactile feedback, clear LED indicator illumination, and perfect integration into the center console trim.

Features

Crafted from automotive-grade ABS polymer and finished with electroplated metallic detailing, this switch is engineered for long-lasting durability, scratch resistance, and OEM interior harmony. It features high-sensitivity micro-switch architecture that provides rapid signal transmission to the rear brake actuator motors, preventing intermittent failures and parking brake error messages on the virtual cockpit. Designed as a 1:1 direct drop-in replacement, it utilizes factory-style locking pins and connector terminals, eliminating the need for wiring modifications, cutting, or custom panel fabrication.

Installation & Coding

Installation follows a straightforward plug-and-play process directly into the center console assembly. After unclipping the center console trim or cup holder surround with non-marring interior pry tools, simply disconnect the factory wiring harness and swap out the old switch unit. As a direct hardware replacement, standard installation requires no coding or software adaptation; however, if your vehicle previously stored EPB fault codes, clearing past fault memories via VCDS or OBD11 diagnostic tools after installation ensures immediate trouble-free operation.

Why Upgrade？

Eliminate Safety Risks and Switch Failure

A failing parking brake switch can cause intermittent brake release errors, accidental brake engagement, or dash warning lights that lock the vehicle in park. Replacing it with the 4K0927225B assembly restores immediate, reliable brake control and total driving confidence.

Restore Factory-Fresh Luxury Interior Aesthetics

Daily wear, rings, and fingernails often scratch or peel the soft coating of factory center console switches. Upgrading to a brand-new unit eliminates worn surfaces and restores the refined, premium look expected of a modern Audi cabin.

OEM Fitment Without Modification

Unlike generic universal switches, this unit is manufactured strictly according to genuine dimensions and connector standards. It clips firmly into place with zero panel gap and connects directly to the OEM harness without splicing wires.

FAQ：

Q1:Does this switch require VCDS or dealer coding to work?

For most replacement applications, no coding is necessary. The unit works directly as plug-and-play hardware. If an existing EPB fault code was triggered on your dash before replacement, simply use an OBD2 diagnostic tool to clear old error logs.

Q2:How do I know if my original parking brake button is failing?

Common symptoms include an illuminated EPB warning light on the instrument cluster, unresponsiveness when pulling or pressing the button, an intermittent hill-hold assist failure, or visible cosmetic peeling and sticky button mechanisms.

Q3:Will this part fit both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) vehicles?

The internal electrical switch module and pin layout are functionally identical for all C8 platform configurations; however, we recommend verifying your vehicle’s specific center console layout and original part number before purchasing to ensure 100% cosmetic bracket compatibility.
