5Q1959839 2016-2020 Volkswagen Golf one-button start ignition button

Engine start/stop button switch OE 5Q1959839

This push-button ignition switch is a routine maintenance replacement part, specifically designed to replace a faulty original start/stop button on designated Volkswagen Golf MK7 models equipped with the original keyless entry and start system.

Compatibility Note:

OE Reference Number: 5Q1959839, interchangeable with OE numbers 5G1959839A and 5GG959839. Compatible with 2016-2020 Volkswagen Golf MK7 models. This product is only suitable for vehicles equipped with the original keyless start system; vehicles without the original push-button start system cannot be directly upgraded using this product.

Material and Structure Introduction:

The button housing is made of ABS plastic, with a metal decorative ring and standard "Start/Stop" markings. The main body is made of high-strength engineering plastic, with built-in metal electrical contacts and backlit LED beads. The internal metal contacts undergo basic anti-oxidation treatment; prolonged exposure to high temperature, high humidity, and automotive grease can cause contact delay and backlight dimming.

Main Functions:

Pressing the button sends an electrical signal to the vehicle's ECU, enabling the original one-button start and stop function; the built-in backlight provides good visibility in low-light interior environments.

Note: If the vehicle's ignition failure is caused by a faulty keyless antenna, broken wiring harness, or damaged body control module, replacing this button will not eliminate the problem.

Installation Precautions:

This product conforms to the original vehicle's plug pin definitions and dashboard clip structure, allowing direct replacement of original parts without cutting or rewiring. It is recommended that this be performed by a professional automotive technician to avoid damage due to improper installation. A paper installation manual is not included in the package.

Applicable Scenarios:

Suitable for personal Golf MK7 daily maintenance, used car interior repair, and parts inventory supply for independent automotive repair shops.
